Carbon dioxide (CO2), an economical, safe, environmentally friendly, and renewable carbon source, is an ideal one-carbon building block for organic chemicals, including carbohydrates and fuels. However, its thermodynamic and kinetic stability presents a fundamental obstacle to the use of CO2 in both academia and industry. High-energy reagents, harsh reaction conditions, and special activation m...

Hydrogenation of carbon dioxide to methanol using a homogeneous ruthenium–Triphos catalyst: from mechanistic investigations to multiphase catalysis

The hydrogenation of CO2 to methanol can be achieved using a single molecular organometallic catalyst. Whereas homogeneous catalysts were previously believed to allow the hydrogenation only via formate esters as stable intermediates, the present mechanistic study demonstrates that the multistep transformation can occur directly on the Ru–Triphos (Triphos 1⁄4 1,1,1-tris(diphenylphosphinomethyl) ...

Recyclability of water-soluble ruthenium‒phosphine complex catalysts in multiphase selective hydrogenation of cinnamaldehyde using toluene and pressurized carbon dioxide

The recyclability of water-soluble ruthenium – phosphine complex catalysts was investigated in water – toluene and in water – pressurized carbon dioxide systems for selective hydrogenation of trans-cinnamaldehyde (CAL). For the first hydrogenation run, the selectivity for cinnamyl alcohol (COL) is high for both toluene and dense CO2, because of interfacial catalysis in which the reaction mainly...

Direct synthesis of formic acid from carbon dioxide by hydrogenation in acidic media

The chemical transformation of carbon dioxide into useful products becomes increasingly important as CO2 levels in the atmosphere continue to rise as a consequence of human activities. In this article we describe the direct hydrogenation of CO2 into formic acid using a homogeneous ruthenium catalyst, in aqueous solution and in dimethyl sulphoxide (DMSO), without any additives. In water, at 40 °...

Simulation of methanol synthesis by hydrogenation of carbon dioxide recovered from combustion gases of Fluid Catalytic Cracking Unit of Abadan Refinery

Refineries produce about four percent of the global carbon dioxide emissions, close to one billion tons per year. Globally, the refining sector is the third largest producer of carbon dioxide after the electricity generation and cement industry.This greenhouse gases is a major cause of global warming and climate change and is a serious threat to human health and the environment. One way to redu...
