Published: Feb. 28, 2024

Constructing a p–n heterojunction is an efficient strategy to mitigate the charge-carrier recombination in semiconductors, thereby enhancing photocatalytic activity. This study designed and fabricated core–shell structured photocatalyst β-Ga2O3@CoGa2O4 nanorods, using situ self-template-etched chemical route. The experimental results revealed that CoGa2O4 nanoparticles could be intimately grown on surface of β-Ga2O3 thickness shells easily adjusted by optimizing Co/Ga ratio. Notably, when employed as for conversion CO2 with H2O, without requiring additional sacrificial reagents, nanorods showed improved activity reduction CO yield 21.1 μmol g–1 h–1 compared isolated or CoGa2O4. presence promotes transportation separation through internal electric field caused n-type p-type Consequently, this enhanced during continuous operation. would offer feasible method achieving effective rational design heterojunctions at nanoscale.
