Abstract
The growing concentration of CO(2) in the atmosphere is a serious problem, and efforts to counter this issue are thus highly important. One of the possible approaches to solving this problem is the conversion of waste CO(2) into products with added economic value. Methanol is one of these products with vast potential usage. In this study, indium oxide prepared by a simple precipitation method and modified by nanoparticles of metals from the iron triad were tested as possible catalysts to produce methanol by the method of CO(2) hydrogenation. The prepared catalysts demonstrated a strong dependence of their catalytic activity on used metal. The best selectivity for the production of CH(3)OH was observed for the Fe/In(2)O(3) catalyst at the value of 54.7% at 300 °C. However, due to the higher value of CO(2) conversion, the highest CH(3)OH formation rate was observed at a value of 11.3 mmol/(h*g) at 300 °C for a composite of Ni/In(2)O(3).
