Interface engineering of Co2B-MoO3/MOF heterojunction with rich cobalt defects for highly enhanced NaBH4 hydrolysis

A self-sacrificial template strategy was designed to synthesize Co 2 B–MoO 3 /MOF with rich cobalt defects. The high hydrogen generation rate (6893.1 mL min −1 g −1 ) stems from the synergy between Co 2 B and MoO 3 , coupled with rich Co defects.
