Methanol from CO 2 : For the hydrogenation of carbon dioxide, a marked increase in the methanol selectivity was observed when the reaction was catalyzed by Cu/rod‐shaped ZnO/CdSe with heterojunction structure. Diffusion reflectance, photoluminescence, and ESR spectroscopies clearly indicated an increase in the electron density because of the incorporation of CdSe in the core–shell morphology of Cu/rod‐shaped ZnO (see picture).
