Pharmaceutical residues in aquatic environments have the potential to induce bacterial resistance, subsequently complicating disease treatment and posing a substantial hazard public health. This study demonstrates production of carbon dots from Cassia fistula flowers using hydrothermal process. The obtained were then mixed with zinc oxide create CDs@ZnO-H400. heterojunction photocatalyst exhibited notable enhancement photocatalytic performance due improved charge separation efficiency at interface. CDs@ZnO-H400 catalyst effectively removed two medications, ciprofloxacin paracetamol. Ciprofloxacin showed maximum efficiency, 99.8 % degradation, while paracetamol degradation 75.1 %. stability synthesized was evaluated across four usage cycles EDX-SEM, FTIR, XRD techniques. heterostructure maintained strong photoactivity even after fourth cycle usage.

The photocatalytic oxygen evolution of bismuth oxybromide (BiOBr) is greatly hindered by its low visible-light response and high electron–hole recombination. Nonmetal doping can effectively alleviate these issues, leading to improvement in performance. Herein, Bi2Te3 was introduced as both the Te source morphology-control template improve performance BiOBr. Appropriate amounts are critical maintain ultrathin plate-like structure BiOBr, whereas excessive results formation a flower-like architecture. Oxygen activity disclosed that essential for realizing higher owing sufficient light utilization efficient charge separation. An optimal rate 368.0 μmol h–1 g–1 achieved Te-doped sample, which 2.3-fold undoped BiOBr (158.9 g–1). Theoretical calculations demonstrated induce impurity levels above valence band slightly narrowed gap strengthened absorption range 400–800 nm. More importantly, dopants could act shallow traps confining excited electrons, thus prolonging carrier lifetime. This work provides novel strategy prepare highly photocatalysts simultaneously morphology manipulation nonmetal doping.

CO2 photoreduction into carbon-based chemicals has been considered as an appropriate way to alleviate the energy issue and greenhouse effect. Herein, 5, 10, 15, 20-tetra (4-carboxyphenyl) porphyrin cobalt(II) (CoTCPP) integrated with BiOBr microspheres formed CoTCPP/BiOBr composite. The as-prepared CoTCPP/BiOBr-2 shows optimized photocatalytic performance for conversion CO CH4 upon irradiation 300 W Xe lamp, which is 2.03 2.58 times compared that of BiOBr, respectively. introduced CoTCPP significantly enhanced light absorption properties, promoted rapid separation photogenerated carriers boosted chemisorption molecules. metal Co2+ at center molecules also acts adsorption molecules, boosting convert CH4. possible mechanism was explored by in-situ FT-IR spectra. This work offers a new possibility preparation advance photocatalysts.
