Abstract

Un catalizador que comprende partículas de metales nobles y partículas que contienen titanio. Las partículas de metales nobles y las partículas que contienen titanio están dispuestas sobre una superficie exterior de un soporte. Al menos 20 % en peso del peso total de partículas de metales nobles están adyacentes a al menos una partícula que contiene titanio. Las partículas de metales nobles tienen un diámetro promedio menor que 15 nm y el catalizador tiene un diámetro promedio de al menos 200 micrones. También se describe un método para preparar metacrilato de metilo a partir de metacroleína y metanol usando el catalizador.
