Summary: Co3O4/CN-x%CeO2 (x = 0, 3, 6) composites were prepared by hydrothermal-calcination method for enhanced photocatalytic degradation of formaldehyde (HCHO). The structure, microstructure, and surface functional groups of the samples were investigated using various techniques. The results showed that the Co3O4/CN-3%CeO2 sample exhibited superior degradation performance, with a degradation rate 190% higher than that of the CN sample and maintaining its effectiveness for 24 hours. The sample had an irregular block-based flake and particle structure, with a specific surface area 2.5 times larger than that of the CN sample and contained various functional groups and a mesoporous structure.

Summary: Misuse and overuse of antibiotics have led to the rise of antimicrobial resistance. In agricultural soils, antibiotics and antibiotic resistance genes (ARGs) are mostly found due to the application of livestock and organic wastes. Cattle manure, chicken manure, swine manure, and sewage sludge are the primary sources of antibiotics and ARGs in agricultural soils. Sulfonamides, tetracyclines, fluoroquinolones, and corresponding ARGs are the major types of pollution. Land-use type, soil, and climatic factors affect the concentrations of antibiotics and abundances of ARGs. Mobile genetic elements (MGEs), especially the sul1 gene, play a vital role in promoting the dissemination of ARGs. Better management of antibiotic and ARG contamination in agricultural soils is important for human health.

Summary: Tubular carbon-covered cobalt-doped bi-crystalline phase In2O3 (CoInO-x) was synthesized from cobalt-doped MIL-68(In)-NH2 precursor through one-step calcination. CoInO-x showed significantly higher photocatalytic activity in the degradation of tetracycline hydrochloride (TCH) compared to In2O3. The reaction rate constant of CoInO-500 was 11.02 times higher than that of In2O3 and maintained better photocatalytic performance after four cycles. The enhanced photocatalytic performance can be attributed to cobalt doping creating impurity energy levels, narrowing the forbidden bandwidth of In2O3, and carbon covering serving as a bridge for charge transport.

Summary: A bifunctional material, consisting of Pd-Cu alloy nanocrystals on carbon oxygen co-doped BN, was fabricated to capture and photocatalytically reduce CO2. The CO2 was adsorbed in the form of bicarbonate on the surface of elemental doped BN, and the CO2 molecules were converted to CO at the interfaces of BN and Pd-Cu alloys. The uniform distribution of smaller Pd-Cu nanocrystals on BN created more effective interfaces and led to a higher CO production rate.

Summary: Recently, there has been increasing interest in metal-organic framework (MOFs) based materials for photocatalysis in the fields of energy and environmental remediation. This review focuses on the engineering aspects, morphological developments, and efficiency enhancement of MOFs-based photocatalysts for CO2 reduction and hydrogen production. The review discusses the characteristics, band structures, morphological development, and visible light responsiveness of MOFs, as well as recent developments in MOF semiconductors and enhancement strategies for photocatalytic performance. The applications of MOFs in photocatalytic CO2 reduction and hydrogen production are also systematically discussed.

Summary: In this study, a series of 0D boron carbon nitride quantum dots (BCNQDs) modified 2D Bi4O5I2 (0D/2D Bi4O5I2/BCNQDs) composites were synthesized and applied to photodegradation of tetracyclines (TCs), including tetracycline (TC) and oxytetracycline (OTC). The optimal composite Bi4O5I2/BCNQDs (1 mL BCNQDs) exhibited the highest photocatalytic performance, with degradation rate constants for TC and OTC being 4.95 and 2.17 times higher than that of Bi4O5I2, respectively. This can be attributed to the narrow bandgap property of Bi4O5I2 as an electron acceptor, and the oxygen-containing functional group with negative charge on BCNQDs promoting the formation of photoexcited holes for effective carrier separation.

Summary: Antibiotics pollution in lakes has been widely reported worldwide, but there are limited studies on the distribution of antibiotics in lake water, groundwater, and sediment systems. This study found that the concentration of antibiotics in groundwater decreases with increasing distance from the lake, and during the dry season, most antibiotics showed a significant decline. The distribution of antibiotics varies in different sedimentary environments, with dissolved oxygen and temperature being the main factors influencing their distribution.

Summary: In this study, BN-BiVO4 composites with visible-light response were prepared and used for the degradation of TCs. Results showed that 4BN-BiVO4 displayed superior photocatalytic performance under visible light irradiation, with 3.6 and 2.3 times higher degradation efficiency for TC and OTC compared to BiVO4. The combination of BN and BiVO4 effectively promoted the separation of photogenerated electrons and holes, enhancing the photocatalytic activity. The dominant reactive species were found to be center dot OH radicals and holes. Based on the experiments and characterization analysis, a possible photocatalytic mechanism for TCs degradation was proposed.

Summary: In this study, an efficient Z-scheme heterojunction photocatalyst N-BiFeO3/NH2-MIL-53(Fe) was fabricated, which showed enhanced separation of photogenerated carriers and broadened absorption range of visible light. The catalyst acted as a heterogeneous Fenton-like catalyst and achieved high degradation efficiency for organic pollutants. The photocatalytic experiments demonstrated that the composite exhibited higher degradation efficiency compared with pure N-BiFeO3 and pure Fe-MOF. The effects of catalyst dosage, coexisting ions, and other factors on the degradation performance were investigated, and good stability was shown.

Summary: Heterostructures photocatalysts constructed by boron nitride quantum dots (BNQDs) and MIL-100(Fe) (MNB) were successfully fabricated, showing large surface area, mesoporous structure, and enhanced visible light absorption. The MNB photocatalysts exhibited excellent photocatalytic activity for tetracycline hydrochloride (TC-HCl) degradation, with a photodegradation rate 5.3 times higher than that of pure MIL-100(Fe). The close contact of MIL-100(Fe) with BNQDs and the synergistic effect between them were the main reasons for the improved photodegradation performance.

Summary: Visible-light-driven type II BiVO4/NH2-MIL-53(Fe) (BNMF) heterostructures were successfully synthesized through a facile stepwise hydrothermal method. The BNMF-30 sample showed enhanced photocatalytic activity, attributed to the tight joint interface between BiVO4 and NH2-MIL-53(Fe) which facilitates charge carrier separation and extends light absorption range. Additionally, NH2-MIL-53(Fe) component aids in pollutant adsorption, accelerating oxidation-reduction kinetics at the interface. The main active radicals for enhanced catalytic performance were identified as (OH)-O-center dot, O-center dot(2)-, and h(+).

Summary: A novel Fe-based bi-MOFs heterojunctions material NH2-MIL-88B(Fe)@MIL-100(Fe) was prepared, exhibiting excellent photocatalytic degradation of tetracycline (TC) under neutral conditions with 99.9% removal achieved in 90 min. The enhanced separation and transfer of h(+) and e(-) by the bi-MOFs structure, along with sufficient visible light absorption, contributed to this high performance. Synergistic effects of center dot O-2(-), h(+), and center dot OH in the photodegradation process were observed, with high stability of the Fe-based bi-MOFs demonstrated after five cycles.

Summary: A novel BiPO4/NH2-MIL-53(Fe) composite was synthesized and exhibited better photocatalytic performance compared to pure BiPO4 and NH2-MIL-53(Fe) catalysts individually, with an optimal ratio of 3:1 showing the highest photocatalytic activity of 80% and 94% removal of TCH and IC. Enhanced photocatalytic activity was attributed to more efficient visible light absorption and effective charge separation, making the photo degradation process easier.
