文摘
- •
Facet-coupling NaTaO3/Ta2O5 was obtained by a synchronous etching-growth approach.
- •
The matched etching kinetics of Ta2O5 with the growth rate of NaTaO3 is pivotal.
- •
Facet-coupling NaTaO3/Ta2O5 shows improved light absorption and charge separation.
- •
It exhibits an excellent photocatalytic activity in the absence of any cocatalysts.
