AI Technical Summary
Existing catalysts tend to agglomerate during hydrogen production, making it difficult to expose active sites and resulting in poor improvement in hydrogen production efficiency.
The electrocatalyst employs a heterogeneous structure, comprising a monodisperse transition metal compound support and a noble metal. The transition metal compound support and the noble metal form a heterogeneous structure with sizes controlled within 20 nm and 3 nm, respectively. It is prepared by a hot-injection process to ensure that the catalyst is not prone to agglomeration, and the noble metal and the transition metal compound support exert a synergistic effect.
It improves the exposure rate of active sites of electrocatalyst, enhances hydrogen production efficiency, reduces energy consumption, and achieves efficient hydrogen production in methanol and water co-electrolysis with good byproduct selectivity, thus avoiding CO2 emissions.
