P-doping optimized d-band center position in MoO2 with enhanced oxygen reduction reaction and oxygen evolution reaction activities for rechargeable Zn-air battery

Construction of Mo-Based p–n Heterojunction with Enhanced Oxidase–Mimic Activity for AOPs and Antibiofouling

“…So, CoMoO 4 /MoS 2 exhibits better oxidase-mimic activity than MoS 2 . For a catalyst, adsorption ability toward substrates can also be described clearly by the d-band center theory . When the d-band center approaches the Fermi energy level, adsorption becomes intensive.…”

Structure preferred spinel ferrite on polypyrrole derived N-doped carbon nanofibers as bifunctional electrocatalyst for Zn-air battery

“…After U adds to 1.23 V, the rst and second steps (O 2 + H 2 O + e = OOH * + OH − and OOH * + e = O * + OH − ) become uphill. 43 It can be observed clearly, CoFe 2 O 4 @NCNF needs lower energy than NiFe 2 O 4 @NCNF to complete the barrier. To evaluate ORR activity in theory, limiting potential (the highest potential to make all elementary reactions exothermic) is an important parameter, which is abbreviated as U L (ORR).…”

Structural and compositional analysis of MOF-derived carbon nanomaterials for the oxygen reduction reaction

“…Recently, carbon nanomaterials have garnered significant attention due to their tunable structure, controllable specific surface area, ease of doping and affordability. [7][8][9] Among these materials, graphene, carbon nanotubes (CNT), and mesoporous carbon have been considered promising alternatives to precious metals for ORR catalysts due to their high electrical conductivity and abundance of active sites. Pyrolysis of carbon-containing precursors is a common method for synthesizing carbon nanomaterials, and the choice of precursor material has a crucial impact on the properties of the final product.…”
