| description | An aerosol‐spray‐assisted approach (ASAA) is proposed and confirmed as a precisely controllable and continuous method to fabricate amorphous mixed metal oxides for electrochemical water splitting. The proportion of metal elements can be accurately controlled to within (5±5) %. The products can be sustainably obtained, which is highly suitable for industrial applications. ASAA was used to show that Fe6Ni10Ox is the best catalyst among the investigated Fe‐Ni‐Ox series with an overpotential of as low as 0.286 V (10 mA cm−2) and a Tafel slope of 48 mV/decade for the electrochemical oxygen evolution reaction. Therefore, this work contributes a versatile, continuous, and reliable way to produce and optimize amorphous metal oxide catalysts.
Spraying out catalysts: An aerosol‐spray‐assisted route with metal salts is a reliable route to identify amorphous metal oxide catalysts for electrochemical water splitting. The composition of the products can be precisely controlled from the precursor solution. The catalysts can be continuously collected at a rate of about 0.1 g h−1 from a single home‐made device, and this method is thus scalable and suitable for industrial applications. |
