A series of four PdO/SBA-15 catalysts with 1, 2, 4, 5% (by weight) loading of PdO have been prepared by a conventional impregnation method and are characterized by N 2 -adsorption, low-angle and wideangle XRD, XPS and TEM techniques. The catalysts exhibited very high conversion of cyclohexene and high selectivity of cyclohexenone with 70% t-BuOOH in CH 3 CN. The structural and textural characteristics of catalysts play a crucial role in high conversion and selectivity.

Oxidative coupling of benzylamines to N-benzylbenzylimines under base- and additive-free conditions is achieved over AuNPs/SBA-NH2. Facile preparation, high activity, ease of separation and good reusability are the credentials of AuNPs/SBA-NH2 catalyst.

Ni nanoparticles supported on various mesoporous silicas with 2D (COK-12) and 3D architectures (KIT-6 and SBA-16) exhibited superior catalytic performance in the vapor-phase hydrocyclization of biomass-derived levulinic acid at atmospheric pressure.
