The silica structure and the shape of a as-prepared Pd0.04Au0.96 RCT-SiO2 are indistinguishable from those exposed to b O2 at 773 K for 30 min and to c H2 at 673 K for 1 h as shown by in situ TEM images. d The silica structure is intact and e, f the particles do not sinter after more than 10 cycles of high-temperature treatments and catalytic flow reaction at 363 K. Only a slight increase of the average particle size diameter is observed by TEM measurements of the nanoparticles in used Pd0.04Au0.96 RCT-SiO2.
