Synthesis and enhanced photocatalytic performance of WO3 nanorods @ graphene nanocomposites

Synthesis of hierarchical ZnO–reduced graphene oxide nanocomposites with enhanced adsorption–photocatalytic performance

“…It can apply as promising support material to stabilize inorganic nanoparticles. Many studies have described combination of semiconductor photocatalysts and graphene could result in formation of the graphene-based composites with superior photocatalytic activity [6][7][8][9][10][11][12]. The advance of the photocatalytic activity of the graphene-based composites is attributed to the efficient separation of photoinduced charges and inhibition of electron-hole recombination in carrier transfer processes [13][14][15].…”

Hydrothermal preparation and supercapacitive performance of flower-like WO3·H2O/reduced graphene oxide composite

“…Amongst, graphene, a flat monolayer of carbon atoms arranged in a 2D honeycomb lattice, has been confirmed to be an ideal candidate to fabricate composites due to its fascinating properties such as superior electrical conductivity, large surface area and excellent mechanical flexibility [31]. To date, a variety of WO 3 /graphene composites have been successfully synthesized and their photo/electrochemical and catalytic properties have been widely studied [32][33][34][35][36][37][38]. However, the incorporation of hierarchical WO 3 nanostructures with graphene sheets to prepare composites and their electrochemical performances as supercapacitor electrodes have been few investigated [26].…”

Hybrid nanocomposites with enhanced visible light photocatalytic ability for next generation of clean energy systems

“…Among the visible active semiconductor nanoparticles, the optical [39] and electronic properties, [40] small band gap (2.4 eV-2.8 eV), [41,42] high oxidation power in the valence band, [43] low production cost, reduced toxicity and increased stability [41,42] make tungsten trioxide (WO3) a potential candidate for catalyticbased applications [43][44][45][46][47][48] to be used for water treatment [47] or clean energy generation. [46,49,50] However, because of its low conduction band, [43] high and fast recombination of photo generated electron-hole pairs, pure WO3 does not show high photocatalytic ability which limits its implementation.…”

“…Using liquid phase photoreduction, [44] we designed WO3-based nanoparticles/ GO heterostructure and evaluated their efficiency for stable photocatalysis. WO3 was chosen as starting material based on its above properties and catalytic promises as well as its increased charge separation efficiency [51] and remote oxidation activity when under visible light irradiation.…”
