Efficient photocatalytic degradation of doxycycline by coupling α-Bi2O3/g-C3N4 composite and H2O2 under visible light

Facile Synthesis of Gold Nanoparticles for Anticancer, Antioxidant Applications, and Photocatalytic Degradation of Toxic Organic Pollutants

“…Then, on increasing the concentration of H 2 O 2 to 50, 75, and 100 mM, the removal efficiency was enhanced to 87.88, 90.38, and 91.42%, respectively. Therefore, the positive effect of H 2 O 2 addition was proven through the improvement of MG removal by increasing the concentration of H 2 O 2 that could be accredited to the release of hydroxyl groups that led to the provision of more hydroxyl radicals to the photodegradation system …”

“…Therefore, the positive effect of H 2 O 2 addition was proven through the improvement of MG removal by increasing the concentration of H 2 O 2 that could be accredited to the release of hydroxyl groups that led to the provision of more hydroxyl radicals to the photodegradation system. 40 When the stability and recycling of Zi-AuNPs as a photocatalyst was investigated (Figure 7d) within 100 min of photocatalytic degradation of 25 ppm MG under pH 6, it was observed that the efficiency diminished from 81 to 69.2% after five recycling times, signifying the high applicability of Zi-AuNPs regeneration. The kinetics study of MG removal with the concentration of 25 ppm by Zi-AuNPs is presented in Figure 7e, in which the rate constant (K) was found to be 0.0129 min −1 .…”

The Use of a Novel Graphitic Carbon Nitride/Cerium Dioxide (g-C3N4/CeO2) Nanocomposites for the Ofloxacin Removal by Photocatalytic Degradation in Pharmaceutical Industry Wastewaters and the Evaluation of Microtox (Aliivibrio fischeri) and Daphnia magna Acute Toxicity Assays

“…To overcome the low-efficiency problem of the photocatalysis, the development of a more efficient catalyst system that would effectively improve the catalytic oxidation efficiency and overcome the existing limitations is important. The catalytic activity of the catalyst can be effectively improved by modulating its surface area, preparation method, and changing its properties and structures [42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57].…”

Excellent Photocatalytic Activity of a Novel Hydroxyapatite Based Composite (ZnFe2O4/HAp‐Sn2+) Towards Degradation of Ofloxacin and Norfloxacin Antibiotics

“…al synthesized α-Bi 2 O 3 / g-C 3 N 4 composite for the degradation of doxycycline. [25] The process involves the utilization of H 2 O 2 to enhance the activity. However, here we have applied natural solar light irradiation to carry out the experiment and the photocatalytic process does not involve any oxidizing or reducing agent.…”
