Accelerated Electron Transport and Improved Photocatalytic Activity of Ag/AgBr Under Visible Light Irradiation Based on Conductive Carbon Derived Biomass

Influence of Synthesis Approach on Controlled Microstructures and Photocatalytic Properties of Ag/AgBr-Activated Carbon Composites on Visible Light Degradation of Tetracycline

“…The addition of IPA had a minimal contribution, while the mixture of all the scavengers highlights the ROS contribution in TC degradation in this study. The ˙O2 − significantly enhanced the TC degradation, which aligned well with previous studies [30,63]; thus, the significant role of superoxide anion radical is further explored in this study. The formation rate of superoxide anion radical (˙O2 − ) through the nitroblue tetrazolium (NBT) photocatalytic degradation conversion into diformazan [64] under visible light irradiation was conducted.…”

The ˙O2 − significantly enhanced the TC degradation, which aligned well with previous studies [30,63]; thus, the significant role of superoxide anion radical is further explored in this study. In the scavenging experiment, the degradation rate of TC significantly inhibited around 9-12%, and 29-35%, with the addition of BQ and EDTA-Na2, respectively (Figure 10).…”

“…The Ag NPs (JCPDS file: 071-3762) [27] revealed four diffraction peaks at around 38. , which were all assigned to (111), ( 200), (220), and (311) planes of Ag, [28] respectively. In addition, the peaks of metallic Ag and AgBr, for the AABR-ACK nanocomposites, shifted by 0.2 • , thus being attributed to the interfacial interaction between the AABR nanoparticles and ACK catalyst support [29][30][31]. These attributes for TP-AABR-ACK and DP-AABR-ACK nanocomposites will further promote fast separation of photogenerated charge carriers, thus resulting in high catalytic activities on the removal of TC antibiotics.…”

“…Activated carbon produced from the microwave heating of impregnated pinecone biomass has been reported [25,30].…”

Enhanced degradation of dye mixtures: physicochemical and electrochemical properties of titania dispersed on clinoptilolite, synergistic influence

“…Among the semiconductor materials, titanium dioxide (TiO 2 ) is extensively employed as a photocatalyst for the degradation of toxic and recalcitrant pollutants in wastewater due to its chemical stability and nontoxicity [20,21]. However, the efficiency of pure TiO 2 for degradation of organic pollutants is hindered for practical applications due to its high aggregation tendency, the wide bandgap energy (3.2 eV), the fast recombination rate of photogenerated charge carriers, and post-separation from aqueous solution [22][23][24]. To enhance the efficiency of pure TiO 2 , many studies have been carried out with the incorporation of TiO 2 with inert support materials, since heterogeneous catalysis is a surface-based process [25][26][27], that requires adsorption of pollutant by the support material towards the catalyst surface.…”
