Abstract Hydrogen is a promising alternative fuel for efficient energy production and storage, with water splitting considered one of the most clean, environmentally friendly, sustainable approaches to generate hydrogen. However, meet industrial demands electrolysis‐generated hydrogen, development low‐cost catalyst oxygen evolution reaction (OER) critical, while conventional catalysts are mostly based on precious metals. Many studies have thus focused exploring new nonprecious‐metal catalytic systems improving understandings OER mechanism, resulting in design superior activity compared that catalysts. In particular, use multimetal rather than single‐metal demonstrated yield remarkable performance improvement, as metal composition these can be tailored modify intrinsic properties affecting OER. Herein, recent progress accomplishments systems, including several important groups catalysts: layered hydroxide, spinel, amorphous oxides along theoretical principles enhancement reviewed. Finally, this concluded by discussing remaining challenges achieve further improvements activities.

Carbon dioxide (CO2) electroreduction could provide a useful source of ethylene, but low conversion efficiency, production rates, and catalyst stability limit current systems. Here we report that copper electrocatalyst at an abrupt reaction interface in alkaline electrolyte reduces CO2 to ethylene with 70% faradaic efficiency potential -0.55 volts versus reversible hydrogen electrode (RHE). Hydroxide ions on or near the surface lower reduction carbon monoxide (CO)-CO coupling activation energy barriers; as result, onset evolution -0.165 RHE 10 molar potassium hydroxide occurs almost simultaneously CO production. Operational was enhanced via introduction polymer-based gas diffusion layer sandwiches between separate hydrophobic conductive supports, providing constant selectivity for initial 150 operating hours.
