Ultraviolet-assisted preparation of mesoporous WO3/reduced graphene oxide composites: superior interfacial contacts and enhanced photocatalysis

Efficient conversion of fructose into 5-hydroxymethylfurfural over WO3/reduced graphene oxide catalysts

“…[21][22][23] Therefore, graphene-based materials have become the focal points in the growing eld of carbocatalysis in recent years. [24][25][26] Our previous study proved that Pd@PdO-NDG 27 and Cu NPs@RGO 28 could act as an effective catalyst in organic reactions. In addition, tungsten oxide (WO 3 ), as an acidic catalyst, had been used for biomass conversion.…”

Graphene in Photocatalysis: A Review

“…Lee et al first fabricated the GO wrapped amorphous TiO 2 NPs, followed by a one‐step GO reduction and TiO 2 crystallization via hydrothermal treatment (as shown in Figure B) . Similarly, the composite photocatalysts between graphene/GO and other inorganic metal oxides, such as ZnO, WO 3 , Fe 2 O 3 , BiVO 4 , BiOI, Ag 2 CrO 4 , Cu 2 O, and Ag 3 PO 4 , can also be prepared through the in situ or ex situ synthesis procedures. It should be noted that the interfacial interactions in the in situ synthesized samples are usually stronger than those in the ex situ synthesized ones due to the formation of chemical bonds in some cases, which might be beneficial for the transfer and separation of charges and the reduction of band gaps.…”

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].…”
