Liquid phase in situ spectroscopic investigations of heterogeneous catalysts

Thibault Xavier Florian Fovanna

In this work, we have studied various aspects of catalysts and catalytic processes at the solid-liquid interface, e.g. the reduction of supported PdO, the formation of Pd hydrides, their quantification, the their reactivity in a transient in time-resolved ...

Toward time-resolved laser T-jump/X-ray probe spectroscopy in aqueous solutions

Majed Chergui, Oliviero Cannelli, Giulia Fulvia Mancini, Camila Bacellar Cases Da Silveira, Dominik Kinschel, Rebecca Ann Ingle

Most chemical and biochemical reactions in nature and in industrial processes are driven by thermal effects that bring the reactants above the energy barrier for reaction. In aqueous solutions, this process can also be triggered by the laser driven tempera ...
