Photothermal CO2 Hydrogenation to Methanol over Ni-In2O3/g-C3N4 Heterojunction Catalysts

Year: 2024

Type: article

Abstract: Selective CO2 hydrogenation faces significant technical challenges, although many efforts have been made in this regard. Herein, a Ni-doped In2O3 catalyst supported by g-C3N4 was prepared using the co-precipitation method, and its composition, morphology, specific surface area, and band gap were characterized using TEM, XPS, BET, XRD, CO2-TPD, H2-TPR, UV-Vis, etc. The catalytic hydrogenation reduction of CO2 to produce methanol was tested. Under low-photothermal conditions (1.0 MPa), the hydrogenation of carbon dioxide to methanol is stable, effective, and highly selective, with a spatiotemporal yield of 86.0 gMeOHh−1 kgcat−1, which is 30.9% higher than that of Ni-In2O3 without g-C3N4 loading under the same conditions.
