Summary: In this study, a multifunctional and efficient electrocatalyst P-NiFeOxHy was designed for water electrolysis, which consists of crystalline NiFe phosphide nanocrystals, amorphous P-doped FeOOH, and a crystalline/amorphous heterostructure with superhydrophilic and superaerophobic surface. The optimized design of P-NiFeOxHy showed ultralow overpotentials for oxygen evolution reaction, hydrogen evolution reaction, and urea oxidation reaction. The in-situ Raman spectra and ex-situ XPS analysis were used to investigate the catalytic process and surface structure evolution of P-NiFeOxHy under electrochemical oxidation. Furthermore, P-NiFeOxHy was used as both cathode and anode in a urea-assisted water electrolysis device, which could be driven by a low voltage and even by a solar cell.

Summary: Water electrolysis is an efficient strategy to produce green energy and generate hydrogen. However, the slow kinetics of the anodic half-reaction (OER) decreases the system's efficiency. Urea oxidation reaction (UOR) is considered a promising alternative to OER due to its low potential, abundance of urea sources, and harmless by-products. Non-noble metal catalysts such as nickel, cobalt, molybdenum, manganese, iron, and copper play a crucial role in reducing costs and increasing efficiency. This review explores the electrochemical water splitting reaction, urea electro-oxidation, catalyst synthesis methods, performance measurement parameters, and challenges for future improvements.

Summary: The high energy consumption in water electrolysis systems is attributed to the slow kinetics of the oxygen evolution reaction (OER). Substituting thermodynamically advantageous small molecule oxidation reactions for OER can significantly improve energy conversion efficiency. Studying the in-depth reaction mechanism of complex substrates is necessary due to their elemental composition. This review focuses on the electrooxidation mechanism of different substrate molecules, such as ethanol, urea, and hydrazine, and introduces design ideas and strategies for high-performance electrocatalysts in relation to reaction path selectivity. The challenges in achieving industrial transformation in this field are also discussed.

Summary: Ni/Co-based antiperovskite nitrides, with good electrical conductivity, are being explored as alternatives to Ir/Ru-based catalysts and metal-oxide-based materials for the oxygen evolution reaction (OER). However, their intrinsic activities for OER are insufficient. In this study, a preactivation strategy of modifying antiperovskite nitrides with Fe3+ at the surface is demonstrated, resulting in significant enhancements in OER activity. This work provides a general approach for improving the OER activity of conductive nitride-based electrocatalysts.
