Due to the severe harmful impacts of industrial dyeing wastewater on ecosystems and human health, proper treatment is crucial. Herein, the use of modified graphite as an adsorbent for dyeing wastewater treatment was investigated in this study. The graphite was oxidized and intercalated using a phosphoric acid-nitric acid-potassium permanganate system and then thermally treated at high temperatures to optimize its structure.

Photocatalytic reduction of CO into valuable hydrocarbon fuels is one of the green ways to solve the energy problem and achieve carbon neutrality. Exploring photocatalyst with low toxicity and high-efficiency is the key to realize it. Here we report a lead-free halide perovskite-based 0D/2D CsBiBr/BiWO (CBB/BWO) S-scheme heterojunction for CO photoreduction, prepared by a facile electrostatic self-assembly approach.

However, spent SCR catalysts pose a potential hazard to the environment due to the presence of heavy metals. This problem continues to plague countries with predominantly thermal power generation, and landfills as the dominant disposal method wastes significant metal resources.

However, there is a limited amount of literature on superhydrophobic coatings whose wettability and adhesion can be adjusted by UV irradiation and calcination at the same time. In this study, amorphous SiO microspheres (A-SiO) and nano-TiO particles (N-TiO) were used to fabricate A-SiO/N-TiO composites by wet grinding, and then, they were modified with polydimethylsiloxane (PDMS) and sprayed onto substrate surfaces to obtain a tunable adhesive superhydrophobic A-SiO/N-TiO@PDMS coating.

The designed core-shell TiO(B)/anatase photocatalysts exhibit excellent performance by compared with pure TiO(B) and anatase phase. With the participation of CoP particles, there is drastically enhanced photocatalytic activity of TiO(B)/anatase, and the H-production rate can be up to 7400 μmol·g, which is about 3.
