Visible light assisted production of methanol from CO2 using CdS@CeO2 heterojunction

The production of methanol from CO2 is highly desirable in present scenario due to the excessive CO2 emission. Several photocatalytic materials have been developed for reduction of CO2 into methanol under mild conditions, but things need to be developed soon. In the present work, the solvothermal process had synthesized high surface area CeO2 supported CdS nanocomposite. The catalytic amount of [email protected]2 heterojunction materials was highly active to produce methanol and CO from CO2. [email protected]2 heterojunction demonstrated a good formation of methanol (1534 μmol-g−1) and CO (213 μmol-g−1) under similar conditions. [email protected]2 heterojunction materials were studied using several characteristic techniques, such as XRD, XPS, HR-TEM, UV–vis, FTIR, PL, and Raman spectroscopy, physisorption and EIS analysis. [email protected]2 nanocomposite demonstrated excellent activity and stability with no leaching of metal content at the end of the sixth run.
