A molybdenum sulfo-oxide/cobalt oxysulfide Z-scheme heterojunction catalyst for efficient photocatalytic hydrogen production and pollutant reduction

Abstract

The existence of heterojunction in catalyst structure improves the efficiency of photocatalytic hydrogen production. The two phases of heterojunction can be adjusted simultaneously by doping sulfur and oxygen to achieve...

Abnormal Concentration Detection Method of Chemical Pollutants Based on Multisensor Fusion

“…Therefore, in order to manage chemicals properly, governments have formulated relevant policies to guide the use of chemicals, established appropriate chemical management systems, and determined the maximum concentration of spraying in actual field spraying. Therefore, strengthening the analysis and detection of chemical pollutant concentration is an urgent need to improve economic benefits and protect the ecosystem and human health from possible harm [12,13].…”

Ultrathin black TiO2 nanosheet-assembled microspheres with high stability for efficient solar-driven photocatalytic hydrogen evolution

“…[1][2][3] Hydrogen energy is regarded as a potential energy with the advantages of being clean and renewable and has a high-combustion value, thus attracting widespread attention. [4][5][6] Solar water splitting is the most natural and reliable approach to producing green hydrogen energy. [7][8][9] The semiconductor photocatalysis technology is an effective strategy for converting abundant solar energy into usable hydrogen energy.…”

Effectively enhanced photocatalytic performance of layered perovskite Bi2NdO4Cl by coupling piezotronic effect

“…To address this problem, numerous strategies have been adopted, including defect engineering, [10][11][12] precious metal modification, 13,14 ion doping 15,16 and heterojunction structures. 17 Despite much effort, the improvement in photocatalytic efficiency is still limited by the material synthesis procedures, material stability, and low quantum efficiency to some extent. Hence, the development of novel photocatalytic materials to improve the charge carrier separation efficiency is highly desirable.…”
