“…Reusability tests were conducted for several times, and as shown in Figure 7, the photocatalytic activities of BiVO 4 /RGO‐TNT‐10 towards imidacloprid were relatively stable after 6 times reuse, and the relative degradation efficiency was about 90 % compared with the first experiment, indicating that the catalyst had desirable stability. Other researches have also proved that when BiVO 4 composited with other materials, such as g‐CN or carbon fibers, outstanding durability would be reached [57,58] …”

“…At present, the popular reported bismuth semiconductor photocatalysts mainly include bismuth oxide, [32] bismuth halide oxide, [33] bismuth vanadate, [34] and some complex bismuth containing catalysts [35] . Bismuth vanadate (BiVO 4 ) is a monoclinic and tetragonal phase that exhibiting a higher photocatalytic activity due to a lower band gap (2.4 eV) [36–37] . However, the carrier conduction of BiVO 4 was low, and plenty of photo‐generated electrons will gather in the surface of the catalyst, thus increasing the probability of recombination of electrons and holes, and affecting its photocatalytic activity.…”

The photocatalytic composites based on BiVO4, TiO2 nanotubes (TNT) and reduced graphene oxide (RGO) were synthesized by a one‐step hydrothermal synthesis method. The properties and structures of the samples were characterized by SEM, XRD, UV‐Vis DRS, Raman spectroscopy, photoluminescence spectroscopy and XPS. The effects of RGO‐TNT loading, pH, and dosage of catalysts on degradation efficiency were tested. The best removal results were occured on the condition that loading amount of RGO‐TNT was 10 %, solution pH 10, and catalyst dosage was 1.4 g L−1. The obtained ternary composite with 10 wt% RGO‐TNT exhibited a significant enhancement in photocatalytic efficiency due to the lower band gap with enhanced light absorption and a suppression in the recombination rates of the photogenerated charge carriers, and about 73 % of imidacloprid was degraded within 30 min under UV irradiation. Furthermore, BiVO4/RGO‐TNT‐10 can be reused for 6 times without obvious catalysis loss. Trapping experiments showed that hydroxyl radicals were the main active species in the imidacloprid photocatalytic degradation, and a possible photocatalytic mechanism was proposed based on the results of trapping experiments.

An Efficient photocatalysts for environmental remediation have generated much interest in recent times with a significant emphasis on natural light source. In the present study, activated carbon (AC) incorporated BiVO4 (BV) were synthesized using hydrothermal method and their photocatalytic properties were studied through the photodegradation of Rhodamine B (Rh-B) as a model pollutant under sunlight irradiation. The structural and morphological characteristics of BV and AC-BV nanoparticles have been ascertained, which reveals BV crystallizes in pure monoclinic phase at 120 °C, whereas the modification with AC leads to hexagonal shaped particles. In an effort to develop highly active visible light photocatalysts, small particle size, extended visible absorption in solar spectrum, narrow bandgap and increased surface area were achieved. The inclusion of AC into BV nanoparticles assists the bandgap tuning from 2.4 eV to 1.9 eV which effectively improves the visible light activity of BiVO4. The AC-BV nanoparticles possess mesoporous structure with high surface area of 68.10 m 2 /g which is 9 times greater than that of BV nanoparticles (7.34 m 2 /g). The synthesized AC-BV nanoparticles degrade the pollutant about 98% within 60 minutes whereas BV nanoparticles degrade 47% at same condition. The influence of AC on BV triggers the rate of degradation, due to the narrow bandgap and porosity of the carbon. This study provides a promising photocatalyst to be used for treatment of effluents in large scale.
