“…In the raw EPS, no apparent crystalline Cr-based compounds are observed, possibly due to the amorphous nature of the precursor derived from the mild pretreatment of raw sludge. 37 XRF was performed to determine the elemental composition of the raw EPS. As shown from the elemental analysis results of the EPS (Figure 1c), the main element of the EPS was chromium (about 63%), in addition to Fe (12%), Zn (6%), Ni (4%), Cu (3%), Pb (2%), Si (1%), and P (9%).…”

The recycling of heavy metals from solid wastes and transforming these metals into useful materials, such as metal oxides, nanocomposites, and metal–organic frameworks (MOFs), are beneficial for both sustainable development and environmental protection. MOFs are promising for adsorptive desulfurization, owing to their extremely high surface areas and tunable structures. In this paper, for the first time, MIL-53(Cr) was successfully fabricated from electroplating sludge (EPS) as a metal source through a facile hydrothermal method with and without HF. Our synthetic method is novel, green, scalable, and time-efficient. The obtained MIL-53(Cr) was employed as an adsorbent for adsorptive dibenzothiophene removal from liquid fuel. MIL-53(Cr) with HF exhibits a higher desulfurization capacity (40.11 mg g–1) than that of MIL-53(Cr) without HF (32.80 mg g–1). The improved adsorption performance of MIL-53(Cr) with HF is attributed to adding a small amount of HF, which produces highly crystalline and relativity pure MIL-53(Cr) microrods with a high surface area and porosity, and is due to a robust metal–sulfur interaction. Furthermore, the regenerated adsorbent can retain 94% of its initial sulfur adsorption capability even after 5 cycles, implying that MIL-53(Cr) prepared from Cr-EPS is an efficient adsorbent for fuel desulfurization. This study provides new insight for the production of high-value-added MOF materials from solid wastes following the principle of “resource reuse”.

“…The as-prepared nanoparticles exhibited stable electrochemical Li-storage performances, such as a reversible capacity of 317 mA h/g at 0.5 A/g and a long cycle life exceeding 100 cycles, with nearly no capacity decay (LIB). 95 In another investigation, an electrodeposition method was used to deposit nickel−iron hydroxide (NiFe LDH) nanosheets on chemical-oxidated waste Cu wires. This electrocatalyst exhibited an efficient OER performance with a low overpotential of 275 mV and 390 mV at 20 and 100 mA/ cm 2 , respectively, with excellent stability.…”

Innovation in the field of electrochemistry usually depends on the development of new electrodes, which are still based on natural resource consumption. Until recently, little work focused on the green and sustainable development of electrochemical materials. In this work, we put forward a closed-loop strategy for utilization of biowastes and industrial solid wastes in electrochemical applications. In order to obtain effective electrochemical catalysts, waste components and structures had to be regulated. If one biowaste was used to produce the electrode, the focus was generally put on controlling a specific surface area, pore size distribution, graphitization degree, and surface chemical characteristics. As for one industrial solid waste, controlling factors were metal doping and morphology/crystallinity. After one metal–carbon hybrid was combined by the above two wastes, it was transformed to metal oxide again by thermal treatment. Similarly, the obtained oxide combined with biowaste again to form another hybrid. A closed loop was thus fabricated. After all, waste-derived materials showed reasonable electrochemical performances, which were in favor of developing a “zero-waste” concept.

“…Recently, more attempts have been made in materials to explore high-performance anodes for LIB beyond traditional graphite and analogues, including carbon materials [ 2 , 3 ], transition metal oxides [ 4 , 5 ], silicon materials [ 6 , 7 ], and even alloy materials [ 8 ]. In particular, spinel structured oxides (AB 2 O 4 ) exhibit superior electrochemical performance compared with the corresponding single-component oxides due to the synergy between different metal ions, unique crystal structure, multiple oxidation states, and other characteristics [ 9 , 10 , 11 , 12 ]. However, spinel AB 2 O 4 also has shortcomings such as poor conductivity and volume expansion during charging and discharging, which lead to the problems of large irreversible capacity and poor cycle performance in LIB [ 13 , 14 ].…”

At present, lithium-ion batteries (LIBs) have received widespread attention as substantial energy storage devices; thus, their electrochemical performances must be continuously researched and improved. In this paper, we demonstrate a simple self-template solvothermal method combined with annealing for the synthesis of NiFe2O4 yolk-shell (NFO-YS) and NiFe2O4 solid (NFO-S) nanospheres by controlling the heating rate and coating them with a carbon layer on the surface via high-temperature carbonization of resorcinol and formaldehyde resin. Among them, NFO-YS@C has an obvious yolk-shell structure, with a core-shell spacing of about 60 nm, and the thicknesses of the NiFe2O4 shell and carbon shell are approximately 15 and 30 nm, respectively. The yolk-shell structure can alleviate volume changes and shorten the ion/electron diffusion path, while the carbon shell can improve conductivity. Therefore, NFO-YS@C nanospheres as the anode materials of LIBs show a high initial capacity of 1087.1 mA h g−1 at 100 mA g−1, and the capacity of NFO-YS@C nanospheres impressively remains at 1023.5 mA h g−1 after 200 cycles at 200 mA g−1. The electrochemical performance of NFO-YS@C is significantly beyond NFO-S@C, which proves that the carbon coating and yolk-shell structure have good stability and excellent electron transport ability.
