“…A reaction can also occur between the electrons and the organic pollutants to produced reduction products (equation 5). This mechanisms have been discussed extensively in literature [44][45][47][48] and a summary is shown below using g-C 3 N 4 as an ideal photocatalyst. Furthermore, Table 6 shows the summary of some g-C 3 N 4 based photocatalysts and their organic pollutant removal rates.…”

The scientific community globally have sought for alternative energy generation approaches and environmental remediation techniques to address the changes in consumption patterns of fossil fuel. Semiconductor photocatalysis has been reported as a potential technique to address the aforementioned challenge with graphitic carbon nitride (g-C 3 N 4 ) identified as one of the novel nanomaterial exploration and applications in diverse fields. Many reviews have been reported on g-C 3 N 4 focusing on photocatalysis principles, preparation techniques, photocatalytic enhancement strategies and various photocatalytic applications. However, in this study, a scientometric assessment was conducted to detail the research status on g-C 3 N 4 semiconductor for photocatalytic reduction of CO 2 and visualization of the future research trends. The scientometric review covers 504 published articles retrieved from the SCOPUS database online spanning from 2010 to May 2021. The articles were analysed using the VOSviewer mapping tool software using 10 scientometric indices. The results show 461 authors globally contributed to the topic with 333 articles from China and progressive increase in published articles in diverse journals from 1 in 2010 to 88 in May 2021. Collaborations exist between authors and co-authors from various countries and institutions. The new trending areas for g-C 3 N 4 photocatalysts include nanomedicine, biomedical systems, toxicological industries, food safety monitoring and mathematics.

“…The prepared BiPO 4 , CdS-BiPO 4 , ZnS-BiPO 4 , and CdS-ZnS-BiPO 4 nanocomposites were used to degrade MB under visible light irradiation in a PCX-50A multichannel photochemical reaction system equipped with an LED disc (400-800 nm, 0.42 W/cm 2 , Beijing Perfectlight Technology Co., LTD., Beijing, China) (Figure A1) [35][36][37], and their photocatalytic activity was evaluated based on our earlier reports with modifications [23,[30][31][32][33][34]. Prior to irradiation, 50 mL of 20 mg/L MB (20 ppm) aqueous solution containing 0.20 g of nanocomposites was stirred in the dark for 30 min.…”

In this study, a ternary CdS-ZnS-BiPO4 nanocomposite, synthesized by a solvent-assisted heating method, demonstrated the highest visible light-induced photocatalysis towards the degradation of methylene blue (MB) when comparing with BiPO4, CdS-BiPO4, and ZnS-BiPO4. Transmission electron microscopy (TEM), X-ray powder diffraction (XRD), and UV-Vis diffuse reflectance spectroscopy (UV-vis DRS) were used to characterize the prepared nanocomposites. From UV-DRS results, the energy band gap of the prepared BiPO4 structures was 4.51 eV. When CdS nanoparticles were deposited on BiPO4 surface by a solvent-assisted heating method, the prepared nanocomposites exhibited visible light-responsive photocatalytic degradation toward MB (20 ppm). At a molar ratio of Cd to Zn as 1:7, the prepared CdS-ZnS-BiPO4 nanocomposites exhibited the best photocatalytic activity in degrading 95% of MB dyes, out-performing pure BiPO4, CdS-BiPO4, and ZnS-BiPO4 due to its enhanced charge separation efficiency and the lowered carrier recombination from the efficient p-n junction of unprecedented ternary composites. The investigations on mechanism conclude that the major reactive species responsible for MB degradation are holes and oxygen radicals. For practicality, the degradation efficiency for different dyestuff (Fast Green FCF, Rhodamine 6G, Acid Blue 1, methyl orange, and methyl red) degradation in the different water matrix samples (pond water, seawater, and lake water) by the prepared CdS-ZnS-BiPO4 nanocomposites was evaluated.
