The inactivation effects and mechanisms of Karenia mikimotoi by non-metallic elements modified TiO2 (SNP-TiO2) under visible light

Lijun Hu et al.

Summary: As an advanced oxidation technology, photocatalytic treatment of red tide algae pollution has great research prospects. This study investigated the effects of non-metallic elements (S, N, and P) modified TiO2 on the inactivation of Karenia mikimotoi under visible light. The modified TiO2 showed excellent photocatalytic activity and a reduced band gap, making it a potential treatment for red tide outbreaks.

Synergistic effects of interface coupling and defect sites in WO3/InVO4 architectures for highly efficient nitrogen photofixation

Chen-Yang Pei et al.

Summary: This study systematically investigates the nitrogen photofixation over well-designed oxygen vacancies and interface coordinately modulated WO3/InVO4 samples. The results show that interface modulation can significantly enhance catalytic activity for nitrogen photofixation, especially in the optimized 70 wt% WO3/InVO4 hybrid system with oxygen vacancies.

Improving photocatalytic hydrogen production via ultrafine-grained precipitates formed nearby surface defects of NiFe-LDH nanosheets

Chunlang Gao et al.

Summary: New types of photocatalytic systems formed by combining large-sized NiFe-LDH nanosheets with small-sized TiO2 nanosheets can effectively separate photo-generated electrons and holes, leading to a higher efficiency in photocatalytic hydrogen production. In-situ annealing transmission electron microscopy was used to investigate the microstructural evolution of large-sized NiFe-LDH nanosheets at different annealing stages, revealing the characteristic microstructures of the optimized system. Electrochemical and spectroscopic techniques confirmed the Z-scheme mechanism for fast electron transfer in the system.

Efficient photocatalytic inactivation of Microcystis aeruginosa by a novel Z-scheme heterojunction tubular photocatalyst under visible light irradiation

Yu Chen et al.

Summary: A novel Z-scheme heterojunction tubular photocatalyst, Ag2O@PG, was synthesized and demonstrated efficient algal inactivation under visible light. The optimal algae inactivation efficiency of 99.1% was achieved using Ag2O@PG-0.4 at a dosage of 0.2 g/L. The study also investigated the mechanism of its effect on algal cells. Moreover, the potential application of Ag2O@PG-0.4 in real algal bloom environments was validated.

In situ synthesis of Ag3PO4/C3N5 Z-scheme heterojunctions with enhanced visible-light-responsive photocatalytic performance for antibiotics removal

Hongfei Yin et al.

Summary: The study focused on Ag3PO4/C3N5 nanocomposites with Z-scheme band alignment for the removal of tetracycline hydrochloride. It was found that these nanocomposites exhibited superior photocatalytic activity and photochemical stability, while the performance did not increase with the increasing amount of Ag3PO4. The Z-scheme heterojunctions formed between Ag3PO4 and C3N5 were identified as the main reason for the enhanced photocatalytic activities.

Biochemical and Physiological Responses of Harmful Karenia mikimotoi to Algicidal Bacterium Paracoccus homiensis O-4

Ning Ding et al.

Summary: This study investigated the biochemical and physiological responses of Karenia mikimotoi to the algicidal bacterium Paracoccus homiensis O-4. It was found that O-4 inhibited K. mikimotoi cell growth by inducing oxidative stress and impairing photosynthesis, ultimately leading to algal death. Additionally, the bacterium caused the activation of antioxidant defenses in K. mikimotoi cells to mitigate ROS, while also resulting in lipid peroxidation and reduced photosynthetic pigments.

PtO nanodots promoting Ti3C2 MXene in-situ converted Ti3C2/TiO2 composites for photocatalytic hydrogen production

Jiu-Xiang Yang et al.

Summary: By growing TiO2 nanosheets on Ti3C2 MXene and depositing PtO nanodots, the PtO@Ti3C2/TiO2 photocatalyst effectively enhances hydrogen production efficiency. The photogenerated electrons and holes flow in opposite directions into PtO and Ti3C2 within the composite material, leading to efficient separation of photogenerated carriers.

Siqi Sun et al.

Summary: This study identified and isolated six potential allelopathic substances from marine brown algae Sargassum fusiforme, including ALA and 24-hydroperoxy-24-vinylcholesterol, which showed significant inhibitory effects on the growth of Heterosigma akashiwo. The research also investigated the allelopathic mechanism between ALA and H. akashiwo, revealing a gradual decrease in SOD and POD activities and a reduction in photosynthetic pigments with increasing ALA concentration, suggesting the potential of macroalgae in red tide control.
