Direct selective gas-phase epoxidation of propene with commercially viable conversion has been achieved with catalysts consisting of gold nanoparticles (3–5 nm) supported on large-pore (>7 nm) silylated mesoporous titanosilicates with Ba(NO3)2 as a promoter. The picture provides a plausible mechanism for the synergetic cooperation of the Au and Ti sites, which is superimposed onto a TEM image of the material.
