Copper-ceria solid solution with improved catalytic activity for hydrogenation of CO2 to CH3OH

Highly Active and Selective Multicomponent Fe–Cu/CeO2–Al2O3 Catalysts for CO2 Upgrading via RWGS: Impact of Fe/Cu Ratio

“…In fact, copper can be easily incorporated into the ceria lattice, improving the redox properties of CeO 2 −Al 2 O 3 supported catalysts by means of the presence of redox pairs (i.e., Cu 2+ /Cu + , Cu 2+ /Cu 0 , and Ce 4+ /Ce 3+ ). 12,24 Moreover, the mixed framework of support provides better active metal dispersion when compared to bare alumina supports. 12 Under these premises, this study presents a series of multicomponent Fe−Cu/CeO 2 −Al 2 O 3 catalysts with various Fe/Cu oxide ratios to deliver an optimal RWGS catalytic formulation.…”

The highly efficient removal of HCN over Cu8Mn2/CeO2 catalytic material

“…7(5) were 0.27 nm, 0.31 nm and 0.23 nm, corresponding to the (200) and (111) lattice planes of CeO 2 and (111) lattice planes of CuO. 31 However, there no MnO x phase observed in Fig. 7(5) , this could be explained by the high dispersion of MnO x due to the low loading.…”

“…When introduced MnO x or Fe 2 O 3 , the diffraction peaks of CuO disappeared, indicating the CuO species were dispersed well as amorphous oxides or some Cu species doped into the lattice of CeO 2 and formed Cu–Ce–O solid solution. 31 CuO and MnO x species could strengthen the synergy between CuO and CeO 2 support to restrain the growth of CuO particles. Combined with catalytic activity test results, it could be deduced the bimetal synergistic effect could improve samples' activity by strengthening the interaction between metal oxides and supports.…”

Sonochemical Fabrication of s‐Scheme Hierarchical CdS/BiOBr Heterojunction Photocatalyst with High Performance for Carbon Dioxide Reduction

“…The control CO 2 in the atmosphere is a serious problem. Recently, converting CO 2 into organic fuels, such as formate, [ 1 ] CH 3 OH, [ 2 ] CH 4 , [ 3 ] and HCHO, [ 4 ] is considered as a exploitable solution to improve the pollution of the environment purification and energy demanded.…”

“…This study provides a mild hydrolysis-ultrasonic method for environmental remediation and converting energy using cost-effective semiconductor materials. Recently, converting CO 2 into organic fuels, such as formate, [1] CH 3 OH, [2] CH 4 , [3] and HCHO, [4] is considered as a exploitable solution to improve the pollution of the environment purification and energy demanded.Up to now, numerous methods such as photocatalytic reduction, electrocatalytic reduction, biological transformation,…”
