Abstract

Abstract A melt infiltration strategy allows the encapsulation of transition metal (oxide) nanoparticles in the intra‐wall pores of SBA‐15 supports, providing ultrafine particles that are stable at high temperatures (up to 900 °C, oxidizing–reducing atmospheres). Selective localization of transition metal (oxide) precursor in the secondary pores is achieved in the presence of organic structure‐directing agent occluded in the intra‐wall pores, and by applying an intermediate diffusion step during preparation.
