“…The MnFe 2 O 4 /AC main diffraction peak at 2θ = 33.25° is considered a measurable degree of its crystallinity [42], and its sharpness indicates that the MnFe 2 O 4 /AC possesses a higher crystallinity [29] [43] (ICDD: 04-006-6580). Upon the deposition of different TMOs on the AC surface, the intensity of carbon peaks decreased due to the decrease in graphitization degree, and this proves the combination of metal oxides with AC [5].…”

“…Among them, the microbial fuel cell (MFC) as a bio-electrochemical apparatus has gained researchers' interest owing to its capability of directly harvesting electrical energy during the wastewater treatment process [2,3]. However, the MFCs' widespread application is hindered by the high overpotentials that arise from the sluggish kinetics of the cathode oxygen reduction reaction (ORR) at neutral pH conditions [4,5]. Although platinum (Pt) is the most efficient and widely used electrocatalyst for ORR, its commercial applicability in fuel cells is limited due to its scarcity and high cost [6].…”

For more sustainability and marketing of microbial fuel cells (MFCs) in wastewater treatment, the sluggish kinetics of cathode oxygen reduction reaction (ORR) and platinum scarcity (with its high cost) should be swept away. So, this work aimed to synthesize metal ferrite (MFe2O4; M = Mn, Cu, and Ni) -based activated carbon composites as inexpensive ORR cathode catalysts. The composites were synthesized using a facile modified co-precipitation approach with low-thermal treatment and labeled as MnFe2O4/AC, CuFe2O4/AC, and NiFe2O4/AC. The as-synthesized catalysts are physicochemically characterized by X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared microscopy (FTIR), Barrett-Joyner-Halenda (BJH), scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HR-TEM), and electron spin resonance (ESR). The electrochemical catalytic performance toward ORR was studied in a phosphate buffer solution (PBS) at neutral media via cyclic voltammetry (CV) and linear sweep voltammetry (LSV). MnFe2O4/AC has the highest onset potential (Eonset) value of − 0.223 V compared to CuFe2O4/AC (− 0.280 V) and NiFe2O4/AC (− 0.270 V). MnFe2O4/AC also has the highest kinetic current density (jK) and lowest Tafel slope (− 5 mA cm−2 and − 330 mV dec−1) compared to CuFe2O4/AC (− 3.05 mA cm−2 and − 577 mV dec−1) and NiFe2O4/AC (− 2.67 mA cm−2 and − 414 mV dec−1). The ORR catalyzed by MnFe2O4/AC at pH = 7 proceeds via a 4e− -kinetic pathway. The ESR is in good agreement with the electrochemical analysis due to the highest ∆Hppvalue for MnFe2O4/AC compared to CuFe2O4/AC and NiFe2O4/AC. Thus, MnFe2O4/AC is suggested as a promising alternative to Pt- electrocatalyst cathode for MFCs at neutral conditions. Graphical Abstract

“…Meanwhile, the larger line slope in the low-frequency region confirms that MoS 2 -NPC has a smaller diffusion resistance, resulting in faster reaction kinetics and better HER performance. [26,51] The effect of porous carbon content on electrocatalytic activity was also studied. In the preparation process of the composite, the mass of molybdenum disulfide remained unchanged, 8, 7, 6, and 5 mg of porous carbon was added into the MoS 2 precursor solution, respectively.…”

Special attention is devoted to develop lowcost and highly efficient energy conversion and storage technologies to meet the needs of society development. [3][4][5][6] LIBs and electrocatalytic water splitting for hydrogen evolution reaction (HER) have been considered to be two promising alternatives because of their environmental friendliness, high power density, and availability. [7][8][9] Nevertheless, the scarcity and high price of the HER electrocatalysts (e.g., platinum and other noble metals materials), as well as the low theoretical specific capacity of LIBs, hinder their further development. [10][11][12] Consequently, it is of great significance to explore advanced LIBs electrode materials and water splitting electrocatalysts with low cost, excellent stability, and high activity. [6] As a typical transition metal dichalcogenides (TMDs), MoS 2 has earned considerable attention either as an anode material in battery applications or as HER electrocatalyst owing to its layered structure analogous to graphite, high theoretical capacity (670 mAh g −1 ) and unique sandwich structure with large interlayer spacing (6.2 Å) to facilitate intercalation of alkaline ions. [13,14] Nevertheless, some undesirable disadvantages, such as low conductivity, volume expansion, restacking, and self-aggregation, hinder the direct practical application in electrochemical energy storage and conversion systems. [15,16] To alleviate these problems, one of the valid strategies is incorporating various carbon matrixes including graphene, [17] carbon nanotubes, [18] carbon polyhedra, [19] porous carbons, [20] or carbon sheets, [21] etc. Previous reports have demonstrated that 2D MoS 2 combined with carbon materials could not only increase the conductivity of MoS 2 but also help to stabilize the electrode structure by accommodating the volume variation during cycling, thus enhancing the electrochemical performance. [22][23][24][25] Among the various carbon precursors, natural bio-masses are the most popular candidates because of their low cost, availability, and biodegradable nature. [26] Agar is a biopolymer material derived from marine red algae. It is a mixture of agarose and agaropectin and has been widely used in food, cosmetics, pharmaceutical, and biological media. In recent years, it was also employed to fabricate carbon material for sorbent or supercapacitors. For instance, Zhang and Hu synthesized N-doped hierarchical porous carbon materials for supercapacitor electrodes by MoS 2 has been explored as a potential material for hydrogen evolution reaction (HER) and lithium-ion batteries (LIBs). However, the limited number of active sites and poor conductivity restrain its applications. Herein, a facile method is reported to construct MoS 2 nanosheets (MoS 2 NSs) grown on agar-derived 3D nitrogen-doped porous carbon (MoS 2 -NPC). The as-prepared MoS 2 -NPC composite exhibits good stability and HER electrocatalytic properties with a low overpotential of 209 mV at 10 mA cm −2 and a small Tafel slope of 41 mV dec −1 . Furthermore, as ...

“…The earth-abundant biomass-based carbon sources have thus drawn extensive attention, , as they bear the advantages of being inexpensive, readily accessible, and unique structures. Various biomass materials, such as soybean, shrimp shells, leather, reed waste, and wood, which are rich in cellulose components, have been used as carbon precursors to prepare ORR catalysts. Moreover, carbon support with appropriate porous structure, e.g., a rational ratio of micropore to macropore, greatly favors the electrocatalytic kinetics.…”

The efficiency of the oxygen reduction reaction (ORR) plays a pivotal role in determining the performance of electrochemical energy storage devices, such as rechargeable zinc-air batteries (ZABs). Economical and active electrocatalytic materials are highly desired to drive efficient ORRs. Carbon-nanostructure-based catalysts derived from natural biomass or waste, featuring distinct low cost and sustainability, have been deemed as a promising candidate to substitute expensive noble-metal-based catalysts for ORR. In this work, we report a green and cost-effective strategy to produce nanoporous Fe-NC single-atom electrocatalysts (SACs) for efficient ORRs, using both iron-containing industrial spent acid (SA) residue and the natural biomass of the lotus seedpod (LS) as the main raw materials. The SA features two unique advantages for the SAC synthesis: the Fe3+ acts as a Lewis acid “scissor” to generate rich nanopores, and the HCl can remove aggregates to purify the catalyst. The synthesized Fe-NC SAC shows an improved electrocatalytic activity of the ORR with a high half-wave potential up to 0.866 V versus RHE, as compared to the standard 20% Pt/C one, assigned to its favorable surface area, hierarchically nanoporous structure, and accessible single atomic active sites. The ZAB assembled using the Fe-NC SAC exhibited high-power density (140.2 mW cm–2) and long-term durability. The study demonstrates a sustainable ambition of reusing industrial wastes and converting biomass into low-cost and high-value materials for energy conversion technology.
