The increasing demand for green hydrogen is driving the development of efficient and durable electrocatalysts for the hydrogen evolution reaction (HER). Nickel-molybdenum (NiMo) alloys are among the best HER electrocatalysts in alkaline electrolytes, and here we report a scalable solution precursor plasma spraying (SPPS) process to produce the highly active NiMo electrocatalysts directly onto metallic substrates. The NiMo coating coated onto inexpensive Ni mesh revealed an excellent HER performance with an overpotential of only 26 mV at -10 mA cm with a Tafel slope of 55 mV dec.

- Robust electrocatalysts for the oxygen evolution reaction (OER) are essential for efficient sustainable hydrogen production, and a new family of quaternary mixed-oxides (X-Sn-Mo-Sb) has been developed to address this need.
- These mixed oxides form a stable rutile-type crystal structure with a unique atomic arrangement, leading to beneficial cation vacancies and local disorder that enhance their properties.
- The mixed oxides show remarkable stability in both acidic and alkaline conditions, remaining structurally unchanged during extensive electrochemical tests, making them promising candidates for supporting active metals in OER applications.
