Ag nanoparticles immobilized over highly porous crystalline organosilica for epoxidation of styrene using CO2 as oxidant

Recent Developments on the Catalytic and Biosensing Applications of Porous Nanomaterials

“…Periodic mesoporous organosilicas (PMO) grafted with different transition metals, such as Ti, V, Cr, and Mo, have been used in various chemical reactions [82][83][84]. In 2022, Chatterjee et al prepared a novel PMO using a Schiff base precursor synthesized by the condensation of p-terphenyl-4,4 -dialdehyde and APTMS [85]. The PMO was grafted with Ag NPs to form Ag@PMO, which has been shown to be an excellent catalyst for the oxidation of styrene to styrene oxide using CO 2 as an oxidant under mild reaction conditions (Figure 5) [85].…”

A thiol-containing zirconium MOF functionalized with silver nanoparticles for synergistic CO2 cycloaddition reactions

“…79 Silver-based materials are well known for CO 2 fixation reactions. [80][81][82][83][84][85][86] In particular, for catalytic conversion of terminal epoxides to cyclic carbonates, different silver complexes, 87 silver-based MOFs, 85 and silver nanoparticle incorporated materials have been utilized. 83,84,86,88 In a recent report Li et al demonstrated that silver active sites surrounded by gold nanoclusters show efficiency in the ring-opening of epoxides, and the incorporation of CO 2 can act as a driving force for the conversion.…”
