Research Progress on Carbon Dioxide Hydrogenation for Methanol Production
With the continuous growth of global energy demand and serious environmental pollution issues,some research is focused on seeking a clean and efficient approach to carbon dioxide utilization.Be-ing an important and widely used chemical raw material,methanol also acts as a new type of clean energy with promising prospects.The conversion of carbon dioxide into methanol by catalytic hydrogenation can both reduce carbon dioxide emission and effectively implement the recycle & utilization of carbon re-sources,which is of great significance to alleviate the energy shortage and environmental problems.The art-icle reviews the research progress on the reaction mechanisms and catalysts for hydrogenation of carbon di-oxide to produce methanol.It summarizes the impact of active sites,supports,and structures on catalytic performance in different catalysts.It points out that further in-depth research is needed on improving the dispersion of active metals,regulating the interaction between active metals and supports,and the H/C ratio at active sites.Future research can focus on introducing new supports,optimizing preparation processes,and synthesizing methanol at low temperatures.
