Seminar / Research
On October 27, 2022
Saint-Martin-d'Hères - Domaine universitaire
Professor Ken Sakai from Kyushu University will give a lecture entitled "Advanced Aspects on the Mechanisms of Catalytic Water Splitting and CO2 Reduction". This lecture will be followed by the interventions of Jonathan De Tovar from CBM laboratory and Jérôme Fortage from DCM laboratory.
Title of the Talk:
Advanced Aspects on the Mechanisms of Catalytic Water Splitting and CO2 Reduction
Name and Affiliation:
Ken Sakai, Department of Chemistry, Faculty of Science, Kyushu University, Fukuoka, Japan
Short Abstract:
Among various approaches attempting to develop renewable energy cycles, solar hydrogen production via water splitting still receives continued attention in relation to the recent advancement in the hydrogen fuel cell technology. Moreover, there is an increasing demand to develop human technology on the carbon dioxide capture and reduction to value-added chemicals to prevent the global warming and the disastrous climate changes associate with it. With these perspectives in mind, our recent interests still concentrate on the basic studies in order to gain important insights as well as rational strategies to develop truly active systems for water oxidation and reduction together with CO2 reduction using various transition metal molecular to heterogeneous catalysts. In the beginning, the concept of two-electrode solar water splitting systems which permit H2 separation at a dark cathode will be discussed. The talk will further introduce (i) some of our recent progresses made in the development of highly active Co-NHC HER catalysts, (ii) the environmentally friendly photocatalytic CO2 reduction by Co-porphyrins operated in fully aqueous media , (iii) the mechanism of O-O coupling pathway for a monocobalt polymolybdate CoPOM(Mo) water oxidation catalyst, and (iv) the theoretical studies on the electrocatalytic HER by platinum subnanoclusters with an implication of its relevance to the HER catalyzed by standard platinum electrodes.
