Advances in catalytic homogeneous hydrogenation of carbon dioxide to methanol

Recent Developments in the Modelling of Heterogeneous Catalysts for CO2 Conversion to Chemicals

“…Understanding of elementary processes on atomic scale is important to design novel catalysts with outstanding activity and selectivity towards specific compounds. Here, a review of the current understanding of CO 2 catalytic hydrogenation to fuels and chemicals including CO, CH 4 , CH 3 OH and HCOOH and mechanisms with different reaction pathways and elementary steps is presented.…”

“…In the case of chemical CO 2 utilization, CO 2 is typically converted by thermochemical processes such as homogeneous [3,4] and heterogeneous hydrogenation; [5,6] and by biochemical, [7] electrochemical, [5,[8][9][10] photochemical [11] and photoelectrochemical reduction processes. [12,13] The use of specific catalysts is key to overcome high activation energy barriers, to extend the electrode life and stability or to capture solar radiations that generate excitons (e À + hole) for CO 2 reduction.…”

Homogeneous Catalytic Hydrogenation of CO2 to Methanol – Improvements with Tailored Ligands

“…Although several heterogeneous materials are known for the direct conversion of CO 2 to methanol, similar homogeneous approaches with organometallic complexes are still at an early stage. [10] The majority of these molecularly-defined systems work under basic conditions. For instance, basic pre-activation of CO 2 with amines and subsequent hydrogenation of the intermediate to methanol in a second step was demonstrated by the groups of Milstein, [11] Sanford, [12] Olah/Prakash, [1b,13] and Wass, [14] as well as Martins and Pombeiro.…”

Location Planning for the Production of CO2‐Based Chemicals Using the Example of Olefin Production

“…Major advances in the commercialization of CO 2 ‐based syntheses are currently evident in methanol synthesis. Techno‐economic studies on the operation of CO 2 ‐based methanol synthesis can be found, among others, in Abdelaziz et al, Atsonios et al, Kar et al, and Belotti et al . In addition to methanol, processes for converting CO 2 and H 2 into alcohols (C 2 –C 4 ) are also being developed.…”
