제목 Strategies to design p-n heterojunction CuxO-TiO2 photocatalysts for CO2 Reduction into Methane
초록 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.
