Reasons for the deactivation of Pt0/TiO2 photocatalyst treated by inert gas N2
Source abstract
Abstract
Abstract The effect of N 2 treatment on the photocatalytic activity of Pt 0 /TiO 2 was investigated. The results showed that after treatment at 500 °C in N 2 , 70% of the photocatalytic activity of 1.0 wt.% Pt 0 /TiO 2 was lost by the evaluation of photocatalytic oxidation reaction of C 3 H 6 . Transmission electron microscopy (TEM) and Ar + ion sputtering tests revealed that in the course of high-temperature N 2 treatment, the size of Pt 0 particles on TiO 2 increases and a strong interaction between metal and support, i.e. Pt 0 particles encapsulated by Ti x O y , happens, which are the reasons for the deactivation of Pt 0 /TiO 2 photocatalyst treated by high-temperature N 2 .
