Interface charge density modulation of a lamellar-like spatially separated Ni9S8 nanosheet/Nb2O5 nanobelt heterostructure catalyst coupled with nitrogen and metal (M = Co, Fe, or Cu) atoms to accelerate acidic and alkaline hydrogen evolution reactions

Recent strategies for activating the basal planes of transition metal dichalcogenides towards hydrogen production

“…14,166,167 Here, we would discuss the synergistic effect 168,169 and the interfacial charge transfer [170][171][172] originating from heterostructures. So far, the synergistic effects have also been frequently observed in hydroxide/TMDC, [173][174][175][176] TMDC/ TMDC, [177][178][179][180] oxide/TMDC, [181][182][183] and others. [184][185][186][187] As discussed in Section 2, the high adsorption energy of H 2 O hinders the generation of H ad intermediates, leading to sluggish kinetics in alkaline solution.…”

Developments and Perspectives on Robust Nano‐ and Microstructured Binder‐Free Electrodes for Bifunctional Water Electrolysis and Beyond

“…To address these challenges, and inspired by the advantages of the nano‐ and microstructured architectures, researchers have integrated a range of nano‐ and microstructures with substrates to optimize the electrocatalytic performance from the laboratory scale to the commercial level. [ 28,55,77,78–81 ] These have included foams (Ni, Fe, and Cu), stainless steel (SS), foils (Cu, Ti, and Al), Si wafer, transparent conductive substrates (ITO and FTO) and carbon‐based materials such as graphene foam (GF), highly oriented pyrolytic graphite (HOPG), carbon cloth (CC), carbon paper (CP), carbon fibers (CF), carbon nanotubes (CNTs), and GC.…”

Understanding the role of Cl doping in the oxygen evolution reaction on cuprous oxide by DFT

“…Commonly, doping is an essential way to adjust the electrical properties of metal oxides through the introduction of a new element [22][23][24][25] and previous experimental studies have shown that the resistivity of Cl-doped Cu 2 O is much lower than that of Cu 2 O. [26][27][28][29] Recently, Yu et al found that Cl-doped Cu 2 O can drive the OER coupled with CO 2 reduction under visible light. 30 Compared to pristine Cu 2 O, Cl-doped Cu 2 O demonstrates superior stability and better photocatalytic activity for the OER.…”
