Halloysite nanotubes supported BiVO4/BaSnO3 p-n heterojunction photocatalysts for the enhanced degradation of methylene blue under visible light

Xingyu Chen et al.

Summary: A novel BiVO4/BaSnO3@HNTs composite was constructed using a facile precipitation method, and the photocatalytic performance was evaluated by the degradation efficiency of methylene blue (MB) dye. Results showed that the BiVO4/BaSnO3@HNTs photocatalyst exhibited significantly enhanced catalytic efficiency for MB degradation under visible light. The improved performance can be attributed to the rapid carrier separation induced by BiVO4/BaSnO3 p-n junctions and the large specific surface area and adsorption capacity provided by HNTs.

Fabrication of CuMn2O4/Co3O4 nanocomposite heterojunctions for efficacious visible light-induced degradation of antibiotics

Sumaya H. Almenia et al.

Summary: The synthesis and design of heterojunction nanocomposites with remarkable photocatalytic performance remain a challenge. In this work, CuMn2O4/Co3O4 nanocomposite heterojunctions were fabricated using a sol-gel strategy with soft template assistance. The CuMn2O4/Co3O4 nanocomposites exhibited significant enhancement in degradation efficiency and achieved 100% degradation of tetracycline within 75 min. The enhanced photocatalytic ability was attributed to the construction of heterojunction, synergistic effect between CuMn2O4 and Co3O4, enlarged surface area, strengthened effective charge mobility, and narrowed bandgap energy.

Ta3N5/CdS Core-Shell S-scheme Heterojunction Nanofibers for Efficient Photocatalytic Removal of Antibiotic Tetracycline and Cr(VI): Performance and Mechanism Insights

Shijie Li et al.

Summary: Ta3N5/CdS core-shell S-scheme heterojunction nanofibers were prepared by growing CdS nanodots on Ta3N5 nanofibers via a wet-chemical method. These nanofibers exhibit excellent photocatalytic degradation and mineralization performance for tetracycline, as well as efficient photocatalytic reduction performance for Cr(VI). The formation of a favorable core-shell fiber-shaped S-scheme heterostructure with tightly contacted interface and maximum interface contact area ensures effective photo-carrier disintegration and optimal photo-redox capacity, leading to superior photo-redox ability. Furthermore, critical environmental factors and the degradation products of tetracycline were evaluated, and the decrease in eco-toxicity of TC intermediates was confirmed.

A CuMn2O4 spinel oxide as a superior catalyst for the aerobic oxidation of 5-hydroxymethylfurfural toward 2,5-furandicarboxylic acid in aqueous solvent

Xiaoyue Wan et al.

Summary: A CuMn2O4 spinel oxide prepared via a freezing-assisted sol-gel method was used as a catalyst for the aerobic oxidation of 5-hydroxylmethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) in aqueous solvent, achieving a high FDCA yield. Kinetic studies showed the primary reaction route and the rate-determining step over the CuMn2O4 spinel. Characterization measurements indicated that the enrichment of Mn species and appropriate metal ratios on the catalyst surface facilitated oxygen mobility and enhanced FDCA formation through synergistic effects between Mn and Cu.
