“…To date, materials such as carbon nanotubes, graphene, carbon nanofibers and activated carbon, were successfully applied as electrocatalysts for energy conversion/storage reactions [145,[148][149][150][151][152][153][154][155]. However, it should be noted that the production of these materials is complex and expensive, which limits their practical application [156]. Additionally, these are produced from petrochemical products via energy-intensive or harsh synthetic processes.…”

“…During hydrogen evolution reaction (HER), H 2 molecules are generated in acidic electrolyte via the reduction of H + ions (Equation ( 15)) [141,156]. The overall process occurs through two steps: the first one involves the adsorption of a hydrogen atom (Volmer step), followed by the combination of two adsorbed hydrogens (Tafel step) or the reaction with a proton (Heyrovsky step) [141].…”

“…On the other hand, in M-BCH electrocatalysts, Pt is usually replaced with non-precious materials, namely transition metal NPs [198] or metal phosphides [169], carbides [147,199] or sulfides [156]. For instance, Min et al decorated a porous carbon membrane derived from biomass with Co NPs by mixing pomelo peels with Co(NO 3 ) 2 and annealing the mixture in air at 260 • C, followed by carbonization at 800 • C in N 2 atmosphere [198].…”

Metal-Supported Biochar Catalysts for Sustainable Biorefinery, Electrocatalysis, and Energy Storage Applications: A Review

Biochar (BCH) is a carbon-based bio-material produced from thermochemical conversion of biomass. Several activation or functionalization methods are usually used to improve physicochemical and functional properties of BCHs. In the context of green and sustainable future development, activated and functionalized biochars with abundant surface functional groups and large surface area can act as effective catalysts or catalyst supports for chemical transformation of a range of bioproducts in biorefineries. Above the well-known BCH applications, their use as adsorbents to remove pollutants are the mostly discussed, although their potential as catalysts or catalyst supports for advanced (electro)catalytic processes has not been comprehensively explored. In this review, the production/activation/functionalization of metal-supported biochar (M-BCH) are scrutinized, giving special emphasis to the metal-functionalized biochar-based (electro)catalysts as promising catalysts for bioenergy and bioproducts production. Their performance in the fields of biorefinery processes, and energy storage and conversion as electrode materials for oxygen and hydrogen evolutions, oxygen reduction, and supercapacitors, are also reviewed and discussed.

“…The performance of Au/MoS 2 QDs hybrid was compared with MoS 2 QDs, Au NPs and 20% Pt/C. The overpotential corresponding to the current density at 10 mA•cm −2 is related to synthesis of solar fuel, so it is very meaningful to compare the overpotential at 10 mA•cm −2 [24]. As shown in In Fig.…”

Ultra-small MoS 2 quantum dots (QDs) with an average size of 2.48 nm coated on Au nanoparticles with a core-satellite structure (Au/MoS 2 QDs) are successfully prepared by a self-assembly strategy through the strong bonding between Au and S. Benefited from the unique structure, the Au/MoS 2 QDs hybrid exhibits outstanding electrocatalytic performance toward hydrogen evolution reaction (HER). The Au/MoS 2 QDs hybrid needs overpotentials of 112, 146, and 206 mV to approach current densities of 10, 20, and 50 mA•cm −2 in 0.5 mol•L −1 H 2 SO 4 (pH = 0.3), respectively. And a low Tafel slope (83 mV•dec −1) is obtained. The catalyst also displays satisfactory stability and durability, indicating a negligible current density loss after 20 h of electrolysis. The high hydrogen generation activities and stability are attributed to the great number of active sites, high conductivity and synergistic effects between gold nanoparticles (Au NPs) and MoS 2 QDs. Last but not least, this strategy opens up a favorable way to combine MoS 2 QDs with other metals.

As part of ongoing efforts to realize a low‐carbon and hydrogen‐based society, there is an increasing demand for high‐performance electrocatalysts, which are key materials for fuel cells and water electrolysis systems. Although platinum group metals exhibit high catalytic activity, increasing production costs due to resource constraints, limited countries of production, and geopolitical supply issues are threatening their use. Therefore, it is crucial to make substantial changes in resource utilization for the sustainable production of electrochemical catalysts. Herein, the preparation of trifunctional biomass‐derived electrocatalysts for the oxygen reduction reaction and oxygen/hydrogen evolution reactions by the pyrolysis of cellulose nanofibers from ascidian tunicates, dried blood meal, and cyanocobalamin is reported. The combination of N, P, FeN4, and CoN4 structures incorporated in the carbon network leads to high electrochemical performance comparable with rare‐metal‐based electrocatalysts and other carbon alloy electrocatalysts. This work provides a possible strategy for fabricating high‐capacity energy storage devices from biomass resources such as industrial waste without the need for rare metals or other harmful heavy metals.
