Nanocubes phase adaptation of In2O3/TiO2 heterojunction photocatalysts for the dye degradation and tracing of adsorbed species during photo-oxidation of ethanol

lIn2O3 nanorods combined with TiO2 nanoparticles promote the electron-hole transfer rate.lThe heterojunction of In2O3/TiO2 nanocubes (ITNC) effectively degrades the MG dye.lThe H2O and O2 are the main reactive species induced from the nanocube phase for the efficient degradation.lThe photooxidation of ethanol was evaluated by the DRIFT study in In2O3 implanted with TiO2 nanoparticles.
