3D Co3O4‐RuO2 Hollow Spheres with Abundant Interfaces as Advanced Trifunctional Electrocatalyst for Water‐Splitting and Flexible Zn–Air Battery

“…The ever-increasing global energy demand, as well as environmental pollution, have inspired researchers to exploit sustainable energy and equipment, for example, water electrolysis, fuel cells, and rechargeable metal-air batteries. [1][2][3][4][5][6][7][8] Nevertheless, the electrolyte. [38][39][40] Moreover, the rich channels favor the rapid release of generated gas bubbles, exposing abundant active sites timely.…”

“…The ever‐increasing global energy demand, as well as environmental pollution, have inspired researchers to exploit sustainable energy and equipment, for example, water electrolysis, fuel cells, and rechargeable metal–air batteries. [ 1–8 ] Nevertheless, the sluggish reaction kinetics of hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR) lower their operational capability in practical applications, which urges the exploitation of highly efficient electrocatalysts to accelerate the reactions. [ 9–17 ] At present, noble metals present super electrocatalytic performances for HER (Pt), ORR (Pt), and OER (Ir), but the poor multifunctional electrocatalytic properties increase the cost of sustainable energy and assemblies.…”

In situ phase-reconfiguration to synthesize Ru, B co-doped nickel phosphide for energy-efficient hydrogen generation in alkaline electrolytes

“…In contrast, electrocatalytic hydrogen production by combining renewable energy with water splitting is considered one of the most promising methods for hydrogen production. [4][5][6][7] The overall water splitting consists of the HER on the cathode and the OER on the anode. [8][9][10][11] However, the sluggish reaction kinetics of the two halfreactions, particularly for the OER, severely limits the efficiency of hydrogen production, and then hinders the practical applications of hydrogen energy owing to the high cost.…”

Ru, B Co-doped hollow structured iron phosphide as highly efficient electrocatalyst toward hydrogen generation in wide pH range

“…[5][6][7] Among the various available approaches, electrocatalytic water splitting is considered as an efficient and green route for hydrogen generation. [8][9][10][11] As a half reaction, the catalytic activity of HER affects the energy conversion efficiency of water electrolysis. Until now, Pt-based noble-metal catalysts are still the optimal catalysts for HER, but the high cost and scarcity limit their large-scale applications.…”
