A simple ultrasonic-synthetic route of Cu2Se-graphene-TiO2 ternary composites for carbon dioxide conversion processes

A facial route to synthesize a new composite material that consists of TiO 2 nanoparticles grown over the Cu 2 Se-graphene (Cu 2 Se-G) through ultrasonic techniques was reported, which was characterized through some general analyses. The photoreduction of CO 2 to CH 3 OH performance of the Cu 2 Se-g...

Summary:A facial route to synthesize a new composite material that consists of TiO 2 nanoparticles grown over the Cu 2 Se-graphene (Cu 2 Se-G) through ultrasonic techniques was reported, which was characterized through some general analyses. The photoreduction of CO 2 to CH 3 OH performance of the Cu 2 Se-graphene-TiO 2 (Cu 2 Se-G-TiO 2 ) nanocomposite was tested with GC (GCMS-QP2010 SE) under UV and visible light. Our excellent results indicate strong reduction rates of CO 2 compared to original TiO 2 and binary Cu 2 Se-G. We explain in our study the scavenger effect and the mechanism from CO 2 to CH 3 OH.
