Composite of Rh (y) Cr2-y O-3/(Ga1-x Zn (x) )(N1-x O (x) ) Photocatalysts with Hydrophobic Polytetrafluoroethylene (PTFE) Membranes for the Fabrication of Novel Reaction Sites for Water Vapor Splitting Under Visible Light
Rh (y) Cr2-y O-3/(Ga1-x Zn (x) )(N1-x O (x) ) photocatalysts immobilized in polytetrafluoroethylene (PTFE) membranes has been investigated for the design of novel reaction sites. In the case of hydrophobic PTFE membranes, the Rh (y) Cr2-y O-3/(Ga1-x Zn (x) )(N1-x O (x) ) photocatalyst simultaneously evolved both H-2 and O-2, even from an aqueous AgNO3 solution as sacrificial reagent. This indicates that water vapor was split into H-2 and O-2 by the Rh (y) Cr2-y O-3/(Ga1-x Zn (x) )(N1-x O (x) ) photocatalyst particles in the hydrophobic pores of PTFE.
