RETRACTED: Investigation of reaction mechanisms of CO2 reduction to methanol by Ni-C80 and Co-Si60 catalysts

Abstract

The CO 2 reduction on Ni-C 80 and Co-Si 60 are investigated and compared with various metal catalysts. In this work, the pathways to reduction of CO 2 to CH 3 OH are examined. In this study, the desorption energy of CH 3 OH on Ni-C 80 and Co-Si 60 are ca −0.318 eV. The over potentials on Ni-C 80 and Co-Si 60 are lower than various metal catalysts. The Ni-C 80 and Co-Si 60 can be proposed as efficient catalyst for reduction reaction of CO 2 . • Potential of Ni-C 80 and Co-Si 60 for RR- CO 2 was examined by theoretical method. • The pathways to reduction of CO 2 to CH 3 OH on Ni-C 80 and Co-Si 60 are examined. • The over potentials on Ni-C 80 and Co-Si 60 are 0.773 and 0.853 V that lower than metal catalysts. • The Ni-C 80 and Co-Si 60 can be suggested as acceptable catalysts for RR- CO 2 . The CO 2 reduction on Ni-C 80 and Co-Si 60 are investigated and compared with various metal catalysts. In this work, the pathways to reduction of CO 2 to CH 3 OH are examined. The ΔE ad of metals on Ni-C 80 and Co-Si 60 indicated that studied metals have strong bonds with around atoms in Ni-C 80 and Co-Si 60 . In this study, ΔE ad of CO 2 adsorption on Ni-C 80 and Co-Si 60 are higher than ΔE ad to capture the CO 2 on surfaces of various metal catalysts ca −0.156 eV. In this study, the desorption energy of CH 3 OH on Ni-C 80 and Co-Si 60 are ca −0.318 eV. The over potentials on Ni-C 80 and Co-Si 60 are lower than various metal catalysts. The Ni-C 80 and Co-Si 60 can be proposed as efficient catalyst for reduction reaction of CO 2 .
