Ion-exchange synthesis of a micro/mesoporous Zn2GeO4 photocatalyst at room temperature for photoreduction of CO2

Micro/mesoporous Zn2GeO4 with crystalline pore-walls was successfully synthesized via a simple ion exchange method at room temperature. This structure showed enhanced activity in photoreduction of CO2 in comparison with Zn2GeO4 prepared by a solid state reaction.
