The Z-scheme LaCoO3/ZnO (LCZ) heterojunction photocatalyst was designed and prepared using the hydrothermal method. In photocatalytic degradation of tetracycline hydrochloride, LCZ exhibited highest activity with a rate constant 0.0179 min−1,which is 3.2 2.3 times higher than those pure ZnO LaCoO3, respectively. This study presents promising approach potential applications in field degradation. Further theoretical studies reveal that existence can prevent recombination electron-hole pairs, leading to enhanced performance.

Abstract Icing of wind turbine blades will seriously hinder the development power industry, and use biomass resources to solve icing problem is conducive promoting synergistic energy. In this study, ice-phobic coatings with photothermal anti-corrosion properties were prepared by surface modification pyrolysis hydrothermal reaction rice straw biogas residue as raw material. The erosion KOH MoS 2 produced a rough structure material, high-temperature promoted dehydrogenation decarboxylation reactions, which reduced number oxygen-containing functional groups decreased energy coating has superhydrophobic contact angle 158.32°. Due small area in water, was able significantly reduce adhesion strength 53.23 kPa. tunnel test results showed that mass 10.54% 30.08%, respectively, when speed 10 m s −1 temperature − °C. Photothermal performance tests -loaded material had light absorption properties, could rapidly warm up 58.3 ℃ under xenon lamp irradiation cycle stability. loading acts physical barrier, reducing corrosive media substrate, thus improving coating. This study practical application value significance for anti-icing field complex environmental conditions. Graphical

Abstract Increasing the active site of redox reactions on surface photocatalysts and accelerating separation transfer photogenerated electron‐hole pairs are effective methods to improve hydrogen evolution composite photocatalysts. Non‐precious metal Ni photo‐deposition is anchored in situ ZnIn 2 S 4 generate cocatalyst Ni(OH) , which improves photocatalytic performance sample. Under visible light irradiation, semiconductor stimulates photon‐generated carriers. 2+ acts as defect center promote It serves capture light‐generated holes reduce carrier recombination rate so that electrons H + reduction . provides for oxidation reaction materials, allowing be consumed faster improving stability materials. The addition wt% resulted a 10 066 µmol·g −1 ·h /Ni(OH) was 2.5 times higher than pure This paper presents reference case enhancing sulfide its evolution.
