In situ and Operando Spectroscopies in Photocatalysis: Powerful Techniques for a Better Understanding of the Performance and the Reaction Mechanism
Autor: Houeida Issa Hamoud, Lukasz Wolski, Ilia Pankin, Miguel A. Bañares, Marco Daturi, Mohamad El-Roz
Publikováno v: Topics in current chemistry (Cham). 380(5)
In photocatalysis, a set of elemental steps are involved together at different timescales to govern the overall efficiency of the process. These steps are divided as follow: (1) photon absorption and excitation (in femtoseconds), (2) charge separatio
