- W2805192016 abstract "Due to the large-scale consumption of fossil fuel, the increased CO2 concentration in the atmosphere are associated with greenhouse effect and climate change, which have gained increasing research attention [1,2]. Therefore, the possibly captured CO2 can be a potentially useful feedstock if it is converted into other hydrocarbon products. Electrochemical reduction is one of efficient methods for CO2 utilization and recycling, which may be carried out at moderate temperature and atmospheric pressure. It also shows relatively high product selectivity compared with other reduction methods, such as chemical and thermochemical methods. However, the high over-potential for the electroreduction of CO2 is the critical bottleneck. By now, various electrocatalysts have been shown to enable CO2 reduction at low overpotentials, which include metals, metal compounds, and other nanostructures, especially for copper based catalysts. The main conversion products are CO, CH4, HCOOH, and C1-related chemicals. The higher carbon-containing products have only been found in case of copper-related electrocatalysts used. Herein, we firstly reported a novel catalyst of cobalt/graphene nanocomposites for the electrochemical reduction of CO2 to ethanol with a high selectivity and a low overpotential. The XRD, TEM, XPS, Raman characterizations were used to confirm the chemical structure and morphology. The electrochemical performance of the cobalt/graphene catalyst was investigated systematically. A high efficiency towards CO2 electroreduction to ethanol has been found, which is attributed to the synergistic effect of two components. This work highlights the importance of combination of non-copper nanoparticles with carbon on its catalytic activities. It also provides a strategy to design efficient catalysts for CO2 electroreduction to higher carbon products in the future." @default.
