제목 Heterojunction p-n-p Cu2O/S-TiO2/CuO to photocatalytic reduction of CO2 to hydrocarbon
초록 The photocatalytic conversion from CO2 to fuel is currently of great interest. The problem is a challenging one, requiring a stabile, industrially-scalable, broad light-absorbing semiconductor, the energy bands of which align with the CO/CO2 and H2O/O2 potentials. Here we report the synthesis of a unique p-n-p heterojunction material architecture, Cu2O/S-doped TiO2 micro-blocks covered with CuO nanowires using an anodizing and annealing process. Photocatalytic materials excel in photocatalytic conversion of CO2 and water vapor to CH4 in AM 1.5G illumination. The heterojunction material architecture exhibits a methane yield of 2.31 μmol m-2 h-1, a rate approximately ten times higher than TiO2 nanotube array films.
