ROLE OF CEO2 IN THE NI/CE02-AL203 CATALYSTS FOR CARBON DIOXIDE METHANATION

摘要

Carbon dioxide fixation has received much attention recently since CO2 anthropogenic emissions, which have drastically increased in the last decades, were believed to directly impact on global wanning[l-4]. Among the viable solutions to mitigate CO2 emissions, two strategies, either its capture or storage [2-3], or its chemical recycling[5-10] are mainly focused. However, modern society strongly relies on fossil fuels such as methane[5, 7, 8], methanol or dimethyl etherfll, 12], which continuously contribute to further greenhouse effect enhancement. Among the possible fuels options, methane was our target as CO2 methanation was the most thermodynamically advantageous reaction to eliminate CO2 and produce fuels, compared to other pathway to formation of hydrocarbons or alcohols production from CO2[1].
