Catalyst sintering is a major cause of catalyst deactivation, which yearly causes billions of dollars of extra cost associated with catalyst regeneration and renewal. In order to develop more sintering-resistant catalysts, a detailed under?standing of the sintering kinetics and mechanisms is required. It is therefore of great importance to investigate sin?tering in situ, in real time and under realistic catalyst operation conditions (i.e. at high temperatures and pres?sures in reactive gas atmospheres). Today there is a lack of available techniques that allow such studies. Using Pt/SiO2 as model catalyst, this Application Note illustrates that Indi?rect Nanoplasmonic Sensing (INPS) has the potential to fill this gap and provide novel real time data at low cost and with high throughput.
