Abstract

An anion exchange strategy is explored to synthesize Bi₂WO₆ hollow microspheres based on the microscale Kirkendall effect. The as-prepared Bi₂WO₆ hollow microspheres display high CO₂ adsorption capacity and visible light photocatalytic conversion efficiency of CO₂ into methanol without the aid of any co-catalyst.
