“…First, for chalcogenides, some exemplary catalysts are CoMoNiS-nickel foam-31 (CoMoNiS-NF-31), [206] MoS 2 , [207] TaS 2 , [207] Ni 4 Fe 5 S 8 , [208] and Mo-Co 9 S 8 @C. [54] Second, tremendous efforts have been devoted to transition metal pnictides, including phosphides (M x P y , such as Ni 2 P, [209] NiFeP phosphides, [210] porous Mn-doped FeP/Co 3 (PO 4 ) 2 [211] ) and nitrides (such as FeN 4 /NF/EG, [212] N-WC, [213] metallic NiConitrides/NiCo 2 O 4 /GF [214] ). Third, transition metal borides such as TiB 2 [215] were reported by Dasog and co-workers to catalyze OER in acid electrolyte. Note that these compounds are unstable under OER cycling condition and some of them can even decompose/dissolve immediately if contact with acid electrolytes.…”

Water oxidation, or the oxygen evolution reaction (OER), which combines two oxygen atoms from two water molecules and releases one oxygen molecule, plays the key role by providing protons and electrons needed for the hydrogen generation, electrochemical carbon dioxide reduction, and nitrogen fixation. The multielectron transfer OER process involves multiple reaction intermediates, and a high overpotential is needed to overcome the sluggish kinetics. Among the different water splitting devices, proton exchange membrane (PEM) water electrolyzer offers greater advantages. However, current anode OER electrocatalysts in PEM electrolyzers are limited to precious iridium and ruthenium oxides. Developing highly active, stable, and precious‐metal‐free electrocatalysts for water oxidation in acidic media is attractive for the large‐scale application of PEM electrolyzers. In recent years, various types of precious‐metal‐free catalysts such as carbon‐based materials, earth‐abundant transition metal oxides, and multiple metal oxide mixtures have been investigated and some of them show promising activity and stability for acidic OER. In this review, the thermodynamics of water oxidation, Pourbaix diagram of metal elements in aqueous solution, and theoretical screening and prediction of precious‐metal‐free electrocatalysts for acidic OER are first elaborated. The catalytic performance, reaction kinetics, and mechanisms together with future research directions regarding acidic OER are summarized and discussed.

Hydrogen is a clean and renewable energy carrier for powering future transportation and other applications. Water electrolysis is a promising option for hydrogen production from renewable resources such as wind and solar energy. To date, tremendous efforts have been devoted to the development of electrocatalysts and membranes for water electrolysis technology. In principle, water electrolysis in acidic media has several advantages over that in alkaline media, including favorable reaction kinetics, easy product separation, and low operating pressure. However, acidic water electrolysis poses higher requirements for the catalysts, especially the ones for the oxygen evolution reaction. It is a grand challenge to develop highly active, durable, and cost‐effective catalysts to replace precious metal catalysts for acidic water oxidation. In this article, an overview is presented of the latest developments in design and synthesis of electrocatalysts for acidic water oxidation, emphasizing new strategies for achieving high electrocatalytic activity while maintaining excellent durability at low cost. In particular, the reaction pathways and intermediates are discussed in detail to gain deeper insight into the oxygen evolution reaction mechanism, which is vital to rational design of more efficient electrocatalysts. Further, the remaining scientific challenges and possible strategies to overcome them are outlined, together with perspectives for future‐generation electrocatalysts that exploit nanoscale materials for water electrolysis.
