Platinum Single Atoms Strongly Promote Superoxide Formation in Titania-Based Photocatalysis – Platinum Nanoparticles Don't
Original language description
The selective reduction of molecular oxygen to superoxide is one of the key reactions in electrochemistry and photocatalysis. Here the effect of Pt co-catalysts, dispersed on titania, either as single atoms or as nanoparticles, on the photocatalytic superoxide (center dot O2-) formation in O2 containing solutions is investigated. The center dot O2- formation is traced by nitroblue tetrazolium (NBT) assays and in detail by EPR measurements using TEMPO as center dot O2- radical scavenger. The results show that the photocatalytic formation rate of center dot O2- on titania can strongly be enhanced by using Pt single atoms as a co-catalyst, whereas Pt nanoparticles hardly exhibit any accelerating effect. This finding is of considerable significance regarding photocatalytic degradation and photocatalytic oxidative synthesis processes.
