BiVO is considered as one of the important candidate materials for photoelectrochemical water splitting technology. However, the low efficiency of charge separation and poor kinetics of water oxidation limit its performance in PEC water splitting. In this work, a BiVO/MIL-53(FeNiCo) photoanode was constructed by a facile hydrothermal deposition method, exhibiting excellent water oxidation ability under AM 1.

Currently, to deal with the increasingly severe energy crisis and environmental consequences, photocatalytic technology is considered as a promise solution, and the construction of Z-scheme heterostructures are important strategies to maximize the utilization of solar energy and improve photocatalytic performance. Herein, a novel full spectrum-responsive Z-scheme Bi-BiVO-BiTiO heterojunction was constructed by a facile hydrothermal method without any templates or surfactants. A series of detailed analyses revealed that the novel Bi-BiVO-BiTiO heterojunction catalyst were prepared successfully.

This study focuses on achieving high photocatalytic activity using MoS/TiO heterostructures (MOT). To this end, MoS and TiO were synthesized by employing hydrothermal synthesis techniques, and then MoS/TiO heterostructures were synthesized by using 1:1, 1:2, 1:3, and 1:4 ratios of MoS and TiO, respectively. While the structural and electronic changes for the 1:2 and 1:3 ratios were relatively minor, significant modifications in bandgaps and morphology were observed for the 1:1 and 1:4 ratios.

Precise detection of ultralow-level antibiotics, such as picomole, in aqueous environments is significant for human health, however, it presents a great challenge to the adsorption capacity and electrocatalytic ability of sensing materials. Here, we used a one-step hydrothermal method to in situ grow spindle-like CoFe-based metal-organic frameworks (MOFs) with a size of about 50 nm in the region of hydrophilic MXene-loading hydrophobic carbon paper. By combining MOFs with abundant adsorption sites and MXene with high conductivity, the problems of adsorption and electrons transfer of ultralow-level antibiotics have been solved, and achieving precise detection of picomole-level antibiotics.

Dissolved gas analysis (DGA) is an effective method for diagnosing potential faults in oil-immersed power transformers. Metal oxide semiconductor (MOS) gas sensors exhibit excellent performance. However, high operating temperatures can accelerate device aging, thereby reducing the reliability of online monitoring.
