Summary: Tetracyclines (TCs) antibiotics are widely used in human and veterinary medicines, but their active residues released into the environment pose risks to ecosystems and human health. Photodegradation using graphitic carbon nitride (g-C3N4) as a photocatalyst provides a promising solution for complete antibiotic degradation. Doping g-C3N4 with elements improves its activity, broadens its light-responsive range, and reduces electron-hole recombination. This review discusses the design and efficiency of doped g-C3N4 for TCs degradation in aquatic environments.

Summary: Graphite carbon nitride (g-C3N4) is a promising photocatalyst with high catalytic activity, low cost, and high biosafety. However, its application in water purification is limited due to the complexity of underwater photochemical reaction conditions and the disadvantages of g-C3N4 itself. To improve its underwater photocatalytic performance, researchers prepared a g-C3N4/carbon nanotubes (CNT-CN) composite photocatalyst with high specific surface area and enhanced light absorption capacity, which showed significantly improved photodegradation efficiency under different underwater transmission light.

Summary: In this study, MoSe2-NiSe dual co-catalysts with abundant active sites and interfacial electronic structures were assembled on g-C3N4 nanosheets through a solvothermal reaction process. The MoSe2-NiSe/g-C3N4 composite showed improved light absorption and photoelectrochemical properties, achieving a photocatalytic H2 production rate that is 99.25, 1.44, and 3.67 times higher than that of pure g-C3N4 nanosheets, MoSe2/C3N4, and NiSe/C3N4, respectively. The apparent quantum efficiency of MoSe2-NiSe/g-C3N4 reached 4.07% under light at λ = 370 nm. These results indicate that 2D ultrathin g-C3N4 nanosheets with a large surface area and short charge-transfer distance can facilitate light scattering and the transport of photoexcited electrons, while MoSe2-NiSe, as a dual co-catalyst, exhibits strong electronic synergistic interaction between the interfaces, thus improving the conductivity and promoting the electron transfer process.

Summary: The emergence of widespread microbial contamination and drug-resistant bacteria in the water environment poses a severe threat to public health. Photocatalysis using metal-free O-doped g-C3N4/carbon dots (O-CN/CDs) nanosheet photocatalysts has proven to be effective in disinfecting water and improving bacterial disinfection performance. The photocatalysts achieved improved disinfection activity through O-doping, morphology modulation, and loading of carbon dots (CDs) onto the nanosheets. Under visible light irradiation, the optimized O-CN/CDs showed significantly higher inactivation efficiency against methicillin-resistant Staphylococcus aureus (MRSA) compared to bulk g-C3N4 (B-CN), and super-oxide anions radicals (.O2-) and photogenerated holes were identified as the main active species inactivating bacteria.

Summary: Photocatalytic water splitting using g-C3N4 as a photocatalyst is a promising strategy for hydrogen production. However, the poor intrinsic activity of g-C3N4 limits its practical application. In this study, a high-performance porous g-C3N4 photocatalyst with anchored Cu single atoms (CuSAs) was synthesized. The obtained Cu1.5-PCN showed an excellent hydrogen evolution rate under visible light, which was significantly higher than that of PCN and bulk g-C3N4. The results suggest that the Cu-N charge bridge in Cu1.5-PCN extends the light absorption band to the visible-light region, contributing to its high performance in solar energy conversion.

Summary: In layered materials, the stacking sequence can affect ion transport and storage properties. However, the relationship between the stacking sequence and anion transport and storage properties is not well understood. In this study, we found that the stacking sequence influences the nitrate-storage properties of layered double hydroxides. The 2H1 polytype has a higher nitrate-storage capacity compared to the 3R1 polytype. The difference in nitrate-storage capacity is attributed to the soft nature of the 2H1 polytype, which allows minimal lattice changes, while the rigid lattice of the 3R1 sequence requires a larger lattice expansion, hindering ion storage.

Summary: This study investigated the effect of silica loading on the mechanical properties of natural rubber (NR) composites. Results showed that the tensile strength of NR composites reached its maximum value at 20 phr but decreased at high loading due to silica agglomeration. Hardness and modulus increased with increasing silica loading, while elongation at break and abrasion resistance slightly decreased. These findings suggest that NR composites filled with silica become stiffer and harder at higher silica loading, inhibiting the mobility of rubber chains.

Summary: Morphological control of gold nanoparticles (AuNPs) synthesized via solution plasma sputtering (SPS) in sodium chloride (NaCl) solutions has been investigated. The size, distribution, and stability of AuNPs were examined over 30 days of storage. The results show that the NaCl concentration and storage time critically influence the morphological evolution and stability of AuNPs. High NaCl concentration leads to coalescence and sedimentation of AuNPs. Additionally, oxidative etching affects the size and distribution of AuNPs, with larger particles observed at higher NaCl concentrations.

Summary: In order to achieve high-performance lithium-air batteries, a catalyst material that promotes the redox reaction of oxygen needs to be developed. Perovskite-type oxides and hydroxides have been identified as catalyst materials for accelerating the oxygen evolution reaction (OER). CoSn(OH)(6) (CSO) is a promising perovskite-type hydroxide catalyst for the OER. This study reports the synthesis and characterization of CSO using a solution plasma process. The synthesized CSO exhibited highly crystalline structure and showed superior catalytic properties for the OER.
