The Photocatalytic reduction of CO2 with water vapor to fuel offers an exciting prospect for reducing atmospheric CO2 level. However, this strategy still impractical because of low yield. Herein, a mesoporous p-type/n-type heterojunction material, CuxO–TiO2 (x = 1, 2), is synthesized via annealing of Cu/Cu2O nanocomposites mixed with a TiO2 precursor (TiCl4). Such an experimental approach in which two materials of diverse bandgaps are coupled provides a simultaneous opportunity for greater light absorption and rapid charge separation because of the intrinsic p–n heterojunction nature of the material. The optimal sample yields methane of 221.63 ppm·g−1·h−1 owing to broaden is light absorption, efficient charge separation, and mesoporosity. This poster is reviewed ACS Omega 2016, 1, 868−875 paper. |
