Conversely, non-metallic impurities narrow the band gap of Titanium dioxide by shifting the absorption edge toward the visible spectrum. Enhancing catalyst performance in visible/sunlight can be achieved through various strategies such as doping, composites with other metal oxides, surface heterojunction formation, plasmonic decoration using metal particles, and tuning the shape or porous structure of the catalyst.In particular, metal/non-metal doping is receiving a lot of attention because it causes physical and chemical modifications in catalysts. The physical transformation results in smaller crystal size, higher anatase phase content/crystallinity, and larger surface area. Below a certain level of B dopant concentration (1 at%), B appears to occupy interstitial positions, thereby facilitating efficient separation of photogenerated charges. The formation of B-O-Ti bonds contributes to reducing the band gap. Above this level, B occupies both insertion and replacement positions in the grid. The alternative position promotes absorption of visible light. This increase in the absorption edge in visible light is due to hybridization of the boron p orbital with the oxygen 2p orbital. Additionally, B is an excellent disinfectant. In the literature, the additional additives B and Ce have been studied quite extensively for dye degradation and disinfection. Among various additives, Ce has excellent redox properties and offers improved adsorption capacity, providing better contact between catalyst and contaminants for efficient photocatalytic activity. The literature reports that the band gap decreases as new energy levels appear below the conduction band. B showed excellent photocatalytic activity due to its location in the Titanium dioxide lattice. Diaz-Sánchez and co-workers also insightfully noted that photocatalytic activity appears to be enhanced at copper dopant concentration levels in the range of 0.1-2%. However, it is unclear whether the dopant concentration value refers to at% or another unit of measurement. Initial studies on monodoped B/Ce Titanium dioxide catalysts identified 1 at% Ce-TiO2 (higher adsorption capacity) and 1 at% B-TiO2 (significant disinfection activity) as better catalysts, which is consistent with Diaz's observations. I see it. Sanchez and his colleagues. However, the dopant concentration levels in these studies are very arbitrary and there is no understanding of the basis for selecting the dopant concentration, which plays an important role in achieving higher photocatalytic activity. As mentioned in the literature, above a certain/optimal level of impurity concentration, the photocatalytic activity decreases, which is explained by the recombination of photogenerated electron-hole pairs. Excessive impurities block the active centers of Titanium dioxide and reduce the adsorption capacity of contaminants. Therefore, it would be interesting to study the interaction between dopant B and Ce while maintaining the total dopant concentration at 1 at% to determine the synergistic effect leading to improved photocatalytic performance. To date, no such studies have been reported using controlled amounts of boron and cerium as dopants for antibiotic degradation and microbial disinfection. In this study, another additive, silver, was introduced at 0.06 and 0.1 atomic percent to help improve the performance of the photocatalyst. Although this approach has been used to develop perovskite-type oxide catalysts for soot oxidation, it has been relatively less studied for photocatalytic materials. This method helps determine appropriate concentrations of three dopants -boron, cerium, and silver -to solve specific problems and minimizes the amount of chemicals synthesized on a large scale. This issue is very important in the upcoming context of AMR. In this study, a series of bifunctional (degradation and disinfection) catalysts, BxCeyAgzTiO2, were synthesized using an environmentally friendly complexation method of citrate-ethylenediaminetetraacetic acid. The concentration of dopant B was indicated by "x" as it was a relatively high concentration (about 1 at%). The EDTA citrate method provides higher catalyst yields and helps mix metal ions at the molecular level by forming ring structures. The synthesized co-doped photocatalyst was evaluated for ampicillin degradation (reservoir concentration range = 25-420 μg/L, PNEC = 0.5 μg/L) in simulated sunlight and real water matrix. Due to the prevalence of AMR in the Ganga, disinfection of E. coli was also studied using a strain (MTCC 9541) obtained from the Ganga River.
