Recent advances in semiconductor heterojunctions: a detailed review of the fundamentals of photocatalysis, charge transfer mechanism and materials

“…Depending on the duration of illumination, either fragments or complete mineralization of the organic pollutants can be achieved. [18][19][20][21][22][23][24] For further details on ROS generation mechanisms and detection methods, the reader is encouraged to review the comprehensive survey by Nosaka et al 25 What is a heterojunction?…”

“…The salient mechanistic steps in the photodegradation of an organic pollutant are listed below.Photoexcitation: Photocatalyst + hν → e CB − + h VB + Electron–hole recombination: e CB − + h VB + → heat/lightFormation of hydroxyl radical: − OH + h VB + → ˙OHFormation of superoxide anion radical: (O 2 ) Ads + e CB − → − O 2 ˙Formation of hydrogen peroxide: − O 2 ˙ + H + → ˙O 2 H˙O 2 H + e CB − → HO 2 − HO 2 − + H + → H 2 O 2 Photodegradation: Organic pollutant + ROS → Fragments/CO 2 + H 2 OOrganic pollutant + h + → Fragments/CO 2 + H 2 ODepending on the duration of illumination, either fragments or complete mineralization of the organic pollutants can be achieved. 18–24 For further details on ROS generation mechanisms and detection methods, the reader is encouraged to review the comprehensive survey by Nosaka et al 25…”

Controlled morphological synthesis of temperature-dependent CuO nanostructures and their effect on photocatalytic performance

“…In past decades, the synthesis and properties of metal oxide nanostructures with controllable sizes and shapes have attracted increasing attention due to their potential applications in electronchemistry, water purification, and photocatalysis under visible light [8][9][10][11]. As a promising material, copper oxide (CuO), an important p-type semiconductor with a narrow band-gap of 1.4 eV, has many excellent characteristics, such as that it is an abundant resource, non-toxic, and can be easily prepared in diverse shapes of nano-sized dimensions.…”

In2S3 Growth Templated by Aluminogermanate Double‐Walled Imogolite Nanotubes Toward Efficient Visible Light Photocatalysts

“…[5][6][7] Apart from possessing interesting optical properties, In 2 S 3 is also appealing because of its low toxicity and stability under ambient settings. [8,9] One of the strategies for improving the performance of In 2 S 3 is to combine it with other materials. For instance, composites with graphene, [10] ZnO, [11] and MnS [12] have shown improvement in photocatalytic performance over pristine In 2 S 3 .…”
