Enhanced photocatalytic performance of Ga3+-doped ZnO

Application of an Au/B-ZnO/PET–GR flexible composite structure in photocatalysts and supercapacitor electrodes

“…This problem is solved by the following effective paths, including the combination of different species of semiconductor photocatalysts, ZnO nanoparticles modied by doping transition metal ions, the establishment of metalsemiconductor, semiconductor-semiconductor, multiheterojunction semiconductor and other multi-level structure. 4,5 Among them, taking n-ZnO/p-substrate heterojunction as a photocatalyst is a hotspot of research. Moreover, as a member of the family of transition metal oxide, ZnO has high electrochemical activity, pseudo-capacitive and is able to undergo rapid reversible oxidation/reduction, insertion/ deinsertion and adsorption/desorption reactions in the electrochemical environment, which is deemed to be the supercapacitor material with bright prospect.…”

Ga-Promoted Photocatalytic H2 Production over Pt/ZnO Nanostructures

“…Therefore, Ga-doped ZnO materials are good candidates for photocatalysis because of the influence of the dopant on the structural and electronic properties that promote the separation of photoinduced charges. Several works have reported Zn 2 GaO 4 structures as active catalysts for CO 2 photoreduction or H 2 production. − However, Ga-doped ZnO materials have been tested in the degradation of organic dyes in aqueous solutions. − In view of this and of the inherent interest in these kinds of photocatalysts, we have chosen to study their application to alcohol-based sacrificial H 2 production. For this purpose, methanol appears as an ideal model alcohol because of its simplicity and its known reactivity …”

ZnO nanorod arrays on cubic Ag3PO4 microcrystals with enhanced photocatalytic property

“…Besides, the high recombination rate of photo-excited electron-hole pairs limits its photocatalytic property. Therefore, efforts have been paid to improving the photocatalytic performance via various strategies, such as synthesis of one-dimensional (1D) ZnO nanorods, ZnO nanorod arrays, and coupling with other components [10][11][12][13][14][15][16]. Recently, Ag 3 [18].…”
