Reduction on reactive pore surfaces as a versatile approach to synthesize monolith-supported metal alloy nanoparticles and their catalytic applications

Synthesis of hierarchically porous metal oxides and Au/TiO2 nanohybrids for photodegradation of organic dye and catalytic reduction of 4-nitrophenol

“…The tungsten oxide nanowires provided enhanced adsorption of the target molecules, and the gold nanoparticles increase the lifetime of the photogenerated electron-hole pairs. Although many efforts have been made to develop hybrid catalysts consisting of porous metal oxide and Au nanoparticles [30][31][32], a general and economical route to fabrication of such nanohybrids with large-scale hierarchically macro-/mesoporous structures is still a challenge and of particular significance. Many of the reported methods either lack control over the morphology and pore size of oxide supports or require complex preparation processes.…”
