Role of graphene on the band structure and interfacial interaction of Bi₂WO₆/graphene composites with enhanced photocatalytic oxidation of NO

Abstract

Bi2WO6/graphene exhibited higher photocatalytic activity and improved selectivity through the modification of band structure and interfacial interactions.

Hydrothermal synthesis of FeWO4-graphene composites and their photocatalytic activities under visible light

“…FeWO 4 /graphene composites exhibited high capacity and excellent cyclic stability for both Li-ion and Na-ion batteries, using FeCl 3 ·6H 2 O, and Na 2 WO 4 ·2H 2 O as precursors [13]. Graphene-based composite materials have shown significant improvement in the electronic conductivity and transportation, resulting in good photocatalytic properties [14][15][16][17][18][19][20][21]. However, no literature has reported the photocatalytic properties of FeWO 4 -graphene composites as far as we know.…”

Visible-light-driven BiOBr nanosheets for highly facet-dependent photocatalytic inactivation of Escherichia coli

“…The result demonstrates that the work electrode of B001 has higher conductivity, which can facilitate kinetic charge transfer. 47 Thus, the highly facet-dependent bacterial inactivation were attempted in the different amount of system, so that only 6.5-log bacterial cells can be inactivated even within 6 h VL irradiation. Based on the above results, the VLD photocatalytic mechanism for the obviously different bacterial inactivation activities is proposed for B001 and B010 nanosheets (Fig.…”

Influence of interface combination of RGO-photosensitized SnO 2 @RGO core-shell structures on their photocatalytic performance

“…Although, there have been several works on the graphene-photosensitized semiconductor photocatalysts so far, the charge transfer between graphene and semiconductors of graphene-photosensitized composites under ultraviolet (UV) light irradiation was still debatable [20,21]. In addition, the interface combination between graphene and semiconductor (such as electrostatic interaction, chemical bonding) will affect charge transfer efficiency [22][23][24]. Therefore, an investigation of the interface combinations in the graphene/semiconductor composites is important to understand the influence of the structural properties of the composites on their photocatalytic performance [25,26].…”
