Utilization of renewable energy sources is future solution for providing the word energy demand and to solve the problems of climate changes. Carbon dioxide is greenhouse gas and major contributor to the global warming. Hydrogenation process of carbon dioxide with renewable hydrogen will not only mitigate the problem of global warming but will also produce valuable products and renewable energy. The hydrogenation of carbon dioxide to value-added chemicals and fuels is a promising route, providing products such as ...

The alternative way to solve the greenhouse gas emission problems is carbon dioxide (CO2) capture and utilization. CO2 hydrogenation is one of the routes to obtain valuable chemicals and fuels such as methanol. The effect of indium (In) promoter on catalytic system Cu/Zn/SBA-15 has been studied. 1%In/Cu/ZnO/SBA15 and 6%In/Cu/ZnO/SBA15 catalysts have been synthesized by impregnation method and compared with Cu/Zn/SBA-15 catalyst (the content of Cu 30 wt.% and the content of Zn 1.4 wt.%). All catalysts have been cha...

The hydrogenation of carbon dioxide (CO2) to methanol in presence of nanocatalysts has been reported as the one of the most economical and effective ways to reduce CO2 emissions. Over the past several decades, numerous efforts have been made to develop effective catalysts for CO2 hydrogenation to methanol. Among these, the CuO and ZnO based catalysts were highly active for methanol synthesis. Many studies have shown that SBA-15 (Santa Barbara Amorphous or mesoporous silica has good application prospects as a catal...
