Summary: Bi0/BiVO4 was synthesized using ascorbic acid, and its microstructure, morphology, optical properties and photogenerated carriers separation behavior were investigated. The photocatalytic degradation of RhB by Bi0/BiVO4 under visible light irradiation was studied, showing that the photocatalytic performance of Bi0/BiVO4 is significantly improved compared to BiVO4. This enhancement is mainly attributed to the surface plasmon resonance effect of Bi0 deposited on the surface of BiVO4, which expands the light response range and accelerates the separation of photogenerated carriers. This study provides valuable insights for the preparation of excellent catalysts.

Summary: A novel BiVO4 photocatalyst decorated with boron nitride quantum dots (BNQDs), designated as BQBVO, was synthesized via a simple deposition approach. The 0.3BQBVO catalyst exhibited a 5.3-fold enhancement in its ability to degrade naproxen (NPX) under visible light irradiation compared to pure BiVO4. The incorporation of BNQDs accelerated charge carrier transference and O-2(-) played a critical role during NPX degradation. Potential NPX degradation pathways were deduced by analyzing the transformation products via HRAM LC-MS/MS. This research provides theoretical guidance for designing a promising strategy for NPX-contaminated water degradation using BiVO4.

Summary: CdS/Ti3C2/g-C3N4NS Z-scheme composites were prepared and showed enhanced visible light photocatalytic activity compared to Ti3C2/g-C3N4NS and CdS alone, with the degradation capacity for orange II approximately 3.2 and 10.7 times higher, respectively. The use of Ti3C2 as an electron transfer medium in the heterostructure led to improved separation ability of photoinduced e(-)-h(+) pairs, thereby enhancing visible light-driven photocatalytic activity. This study provides new insights for constructing high efficiency Z-scheme heterostructure photocatalysts.

Summary: The corrosion behavior of Ti alloy TA8-1, Cu alloy B19, and Cu under simulated early deep geological conditions in Beishan, China have been studied. The results show that Ti alloy TA8-1 exhibits the lowest corrosion current density and low pitting susceptibility due to the formation of a thin passive film. Cu has a relatively high corrosion current density and low pitting susceptibility. Severe localized corrosion occurs on the surface of Cu alloy B19, leading to a noticeable deterioration in corrosion resistance during the immersion test.

Summary: This study evaluated the effects of adding biochar to lincomycin fermentation dregs (LFDs) composting and found that it can increase compost temperature, enhance organic matter decomposition and remove residual antibiotics. It also reduces the quantity of antibiotic resistance genes and mobile genetic elements, as well as the abundance of persistent ARGs hosts and related metabolic pathways and genes. At the same time, compost decomposition is improved due to enhanced metabolism of carbohydrates and amino acids. Overall, adding biochar to LFDs compost is a simple and efficient way to reduce the risks associated with LFDs composting.

Summary: In this study, nitrogen-doped biochar was used as an activator in a persulfate oxidation system to effectively degrade tetracycline, inactivate antibiotic resistant bacteria, and remove antibiotic resistant genes. The reactive sites for persulfate activation were found to be defects and edge pyridinic nitrogen generated during the nitrogen doping process. Singlet oxygen was the major mechanism for persulfate activation, while sulfate and hydroxyl radicals played minor roles. Tetracycline was degraded through hydroxylation, demethylation, and decarboxylation, and the NLBH/PDS system efficiently inactivated antibiotic resistant bacteria and reduced intracellular antibiotic resistant genes. This study highlights a promising alternative technique for the removal of antibiotics, antibiotic resistant bacteria, and intracellular antibiotic resistant genes in future advanced wastewater treatment systems.
