Silica-embedded metal oxide nanoparticles as epoxidation catalysts: batch and c...
Gomes, Diana M.; Yao, Xingyu; Neves, Patrícia; Antunes, Margarida M.; Pinna, Nicola; Russo, Patrícia A.; Valente, Anabela A.Catalytic epoxidation of olefins gives epoxide chemicals for several end-user products. With the technological advancements of these processes (especially for light olefins), which have importantly contributed to the epoxides market expansion, challenges remain in developing adequate heterogeneous catalysts for converting bulkier olefins, using simple catalyst synthesis procedures, and, on the other hand, study...
Chemical valorisation of biomass derived furanics and carboxylic acids over nio...
Antunes, Margarida M.; Cabanelas, Pedro S.; Skrodczky, Kai; Pinna, Nicola; Russo, Patrícia A.; Valente, Anabela A.Furfural is an industrial renewable platform chemical, which can be converted to useful furanics such as -angelica lactone, carboxylic acids such as levulinic acid and valeric acid, or to higher carbon content via condensation routes for producing drop-in fuel replacements and chemicals with diverse applications. These important conversion processes may be carried out in selective fashions, albeit require adeq...
Single-Step Formation of Metal Oxide Nanostructures Wrapped in Mesoporous Silic...
Skrodczky, Kai; Antunes, Margarida M.; Zhu, Qingjun; Valente, Anabela A.; Pinna, Nicola; Russo, Patrícia A.The integration of metal oxide nanomaterials with mesoporous silica is a promising approach to exploiting the advantages of both types of materials. Traditional synthesis methods typically require multiple steps. This work instead presents a fast, one-step, template-free method for the synthesis of metal oxides homogeneously dispersed within mesoporous silica, including oxides of W, Ti, Nb, Ta, Sn, and Mo.
