“…To improve the activity, selectivity, thermal stability, and resistance to poisoning, the Raney copper catalysts consisting of 50% aluminum and 50% copper-zinc mixture by precipitation with NaOH (Marsden et al, 1980). These catalysts were active for methanol production comparable to that of the commercial copper-based methanol synthesis catalyst, but selective to small amounts of dimethyl ether (DME) by-product.…”

Heterogeneous catalytic hydrogenation of carbon dioxide (CO2) to methanol is a practical approach to mitigating its greenhouse effect in the environment while generating good economic profits. Though applicable on the industrial scale through the syngas route, the catalyst of Cu/ZnO/Al2O3 suffers from a series of technical problems when converting CO2 to methanol directly, which include low single-pass conversion, low methanol selectivity, requiring high pressure and fast deactivation by the reverse water gas shift reaction. Over the years, intensive research efforts have been devoted to proffering solutions to these problems by modifying the existing catalyst or developing new active catalysts. However, the open question is if this type of widely used industrial catalyst still promising for CO2 methanolizing reaction or not? This paper reviews the history of the methanol production in industry, the impact of CO2 emission on the environment, and analyzes the possibility of the Cu/ZnO-based catalysts for the direct hydrogenation of CO2 to methanol. We not only address the theoretical and technical aspects but also provide insightful views on catalyst development.

“…One variation is a catalyst based on Raney copper. These catalysts are produced by caustic leaching of copper/zinc/aluminium alloys (Friedrich et al , 1983a(Friedrich et al , , 1983bMarsden et al , 1980). Recent developments of the route claim very high activity and hence lowering the pressure or increasing the pass conversion (Kokubu, 2000).…”

“…Other basic types of catalyst systems have also been investigated: Raney copper catalysts, copper alloys with thorium or rare-earth oxides, and supported precious-metal catalysts [101][102][103][104][105][106]. Only copper alloy catalysts are reported to have a higher activity than conventional copper -zinc oxide -alumina catalysts [107].…”
