Summary: In this study, a facile strategy was proposed to achieve efficient degradation of antibiotics by peroxymonosulfate (PMS) activation through in-situ growth of single cobalt atoms on polymeric carbon nitride (pCN). The prepared single-atom cobalt catalyst effectively catalyzed the degradation of tetracycline, with CoN/O sites serving as the active site for generating active radical species (singlet oxygen) from PMS activation. This work may expand the strategy for constructing single-atom catalysts and extend its application for the advanced oxidation process.

Summary: Under visible light conditions, bacteria produce superoxide, which is the main reason for the rapid removal of BPA, contributing to 57% of the total removal rate. Bacteria degrade BPA at a higher rate under visible light compared to dark conditions, reaching a total removal rate of 85% within 8 days, which is 4.7 times higher. In addition, the bacteria also showed good degradation ability to pharmaceutical compounds such as diclofenac and fluoxetine.

Summary: In this study, a fast and facile two-step technique to synthesize Ru/RuO2 aerogels for catalyzing overall water-splitting under alkaline conditions is reported. The Ru/RuO2 aerogel exhibits low overpotential for oxygen evolution reaction (189 mV) and hydrogen evolution reaction (34 mV), surpassing RuO2 (338 mV) and Pt/C (53 mV), respectively. When applied at the anode and cathode, the Ru/RuO2 aerogels result in a low potential of 1.47 V at 10 mA cm(-2), exceeding the commercial Pt/C||RuO2 standard (1.63 V).

Summary: To address the sluggish oxygen evolution kinetics of bismuth vanadate (BiVO4) photoanodes, a vanadium oxide (VOx) with enriched oxygen vacancies was grown on BiVO4 photoanodes using a photo-assisted electrodeposition process. The optimized BiVO4/VOx photoanode showed a significantly enhanced photocurrent density of 6.29 mA cm(-2) at 1.23 V, which was 385% higher compared to the pristine counterpart. The presence of oxygen vacancies in VOx improved the adsorption of water molecules and promoted charge transfer during the oxygen evolution reaction, resulting in excellent photoelectrochemical (PEC) water splitting performance.

Summary: The construction of p-n heterojunction structure is an effective method for enhancing electron-hole pair separation in photocatalysts. ZnIn2S4/CoFe2O4 photocatalysts with p-n heterojunctions were prepared using ultrasonication and calcination. The synthesized photocatalysts were analyzed and tested, and their hydrogen evolution rates were evaluated. The ZIS/CFO composite showed improved photocatalytic hydrogen production performance due to the formation of p-n junctions and the internal electric field, leading to enhanced separation of electron-hole pairs and improved hydrogen evolution rate. The composite also exhibited excellent stability and magnetic properties for magnetic recoverability.
