Boosting eco-friendly hydrogen generation by urea-assisted water electrolysis using spinel M2GeO4(M = Fe, Co) as an active electrocatalyst

To enhance the efficiency of hydrogen production, bimetallic oxides with spinel structures, M 2 GeO 4 (M = Fe, Co), were synthesized via a facile one-pot hydrothermal method and were used as electrocatalysts for urea-assisted water electrolysis.
