“…The HER kinetics significantly relies on the H + concentration in the electrolytes. In acidic media, rich H + are provided to adsorb onto the reaction sites and engage in the following steps, while an additional water dissociation is needed to produce protons in neutral and alkaline media for the subsequent steps, which generally serves as the rate-determining step for the neutral and alkaline HER. , As another vital half reaction, OER is the bottleneck of water splitting due to the more complicated electron transfer process and much larger reaction energy barrier than the HER. The adsorbate oxygen evolution mechanism is widely accepted . Four consecutive proton–electron transfer steps occur on the metal active site in alkaline media: OH + * OH * + normale OH * + OH O * + normalH 2 normalO + normale O * + OH OOH * + normale OOH * + OH normalO 2 + * + normalH 2 normalO + normale …”

“…[170] Heat treatment metal oxides in an H 2 and/or N 2 environment generate the same types of imperfections as in air, indicating that the N 2 in air functions as a reduction gas. [170] To control the electrochemical performance of transition-metal dichalcogenides (TMDs), including MoS 2 and WS 2 , [171] imperfection manipulation is widely applied. Temperature and time variations are discovered to influence the imperfection density in an electrocatalyst.…”

“…For the electrochemical catalysts, great efforts have been made for the edge-rich nanostructures, efficient electron transfer interfaces, and the selection of good intrinsic catalysts with strong thermodynamic adsorptions [11][12][13][14][15][16][17]. However, high-performance PEC water splitting is far more difficult because of the requirement of the Z-scheme junction device structures, the matching absorption with sunlight spectrum, carriers' generation and separation [15,[18][19][20][21][22]. Therefore, it is still necessary to search the new materials system and devices structures for finding robust and efficient PEC catalysts to solve the above challenges [23,24].…”
