Dispersed GaOOH rods loaded on the surface of ZnBiNbO₅particles with enhanced photocatalytic activity toward enrofloxacin

Abstract

A GaOOH/ZnBiNbO5 composite was constructed by loading dispersed GaOOH rods on the surface of ZnBiNbO5 particles and characterizations, including SEM-EDS, XRD, FT-IR spectroscopy, XPS, and UV-Vis DRS were performed.

Mixed phases of GaOOH/β-Ga2O3 and α-Ga2O3/β-Ga2O3 prepared by high energy ball milling as active photocatalysts for CO2 reduction with water

“…With increasing the ball milling time, the absorption in the shorter wavelength region (under 220 nm) characteristic of GaOOH became appreciable, while the absorption in the longer wave region given by b-Ga 2 O 3 having a narrower band gap than GaOOH decreased. 23 Thus, from the XRD and UV-vis results, it can be concluded that Ga UV-Vis spectra for the calcined samples are compared in Fig. 3(B).…”

Fabrication of Al doped α-GaOOH nanorod arrays on FTO for self-powered photoelectrochemical solar-blind UV photodetectors

“…Al-O and Ga-O bonds show the similar positions at ∼531.5 eV[25- 27]. The peak at 532.6 eV mainly corresponds to OH bonds in Al doped α-GaOOH and from surface-adsorbed hydroxides[27][28][29]. Besides, O 2 in oxygen-deficient regions at room temperature also partly contributes to the high-energy peak[19,24,30].…”
