“…The hydride pathway exhibits a barrier of 0.4 eV lower than the hydroxyl recombination pathway. The formation of Ti-H species was also proposed to enhance the photocatalytic water splitting to produce H 2 [117,118]. Koocher et al [119] calculated dissociative adsorption of water on a highly reduced reconstructed surface of BaTiO 3 (001) and proposed the formation of surface hydride species, accompanied with surface oxidation.…”

Hydride species on oxide catalysts are widely involved in oxide-catalyzed reactions, and relevant fundamental understanding is important to establish reaction mechanisms and structure-performance relations of oxide catalysts. In this topical review, recent progresses on the formation and reactivity of hydride species on the surface or in the bulk of oxides are briefly summarized. Firstly, characterization techniques for hydride species are introduced. Secondly, formation of hydride species on the surface or in the bulk of various oxides and their reactivity in oxide-catalyzed hydrogenation and dehydrogenation reactions are reviewed. Finally, short summary and outlook are given.

“…The synthesis of NP semiconductor materials is a major challenge in photocatalysis research. Synthesis methods have a significant impact on photocatalysts' morphology, structure, and performance (Sahu & Biswas, 2011;Sun et al, 2019;Taherinia et al, 2019).…”

“…The sol-gel method has a large scope of application in the preparation of inorganic ceramic and glass materials (Czok & Golonka, 2016;Jones, 2013;Wang et al, 2014). Due to its wide range of advantages, including high chemical purity, good uniformity, and controllable morphology (Taherinia et al, 2019;Wetchakun et al, 2012), it has become a common method for photocatalysts synthesis. It is important to mention that a change in molar ratios may lead to different hydrolysis speeds and further different structures and properties (Lu et al, 2013;Wang et al, 2014;You et al, 2012).…”

Organic water pollutants are ubiquitous in the natural environment arising from domestic products as well as current and legacy industrial processes. Many of these organic water pollutants are recalcitrant and only partially degraded using conventional water and wastewater treatment processes. In recent decades, visible light active photocatalyst has gained attention as a non‐conventional alternative for the removal of organic pollutants during water treatment, including industrial wastewater and drinking water treatment. This paper reviews the current state of research on the use of visible light active photocatalysts, their modified methods, efficacy, and pilot‐scale applications for the degradation of organic pollutants in water supplies and waste streams. Initially, the general mechanism of the visible light active photocatalyst is evaluated, followed by an overview of the major synthesis techniques. Because few of these photocatalysts are commercialized, particular attention was given to summarizing the different types of visible light active photocatalysts developed to the pilot‐scale stage for practical application and commercialization. The organic pollutant degradation ability of these visible light active photocatalysts was found to be considerable and in many cases comparable with existing and commercially available advanced oxidation processes. Finally, this review concludes with a summary of current achievements and challenges as well as possible directions for further research. Practitioner Points Visible light active photocatalysis is a promising advanced oxidation process (AOP) for the reduction of organic water pollutants. Various mechanisms of photocatalysis using visible light active materials are identified and discussed. Many recent photocatalysts are synthesized from renewable materials that are more sustainable for applications in the 21st century. Only a small number of pilot‐scale applications exist and these are outlined in this review.

“…A reduced photocatalytic activity of doped-TiO2 was observed at the higher levels of temperature. This is due to the fact that the nanoparticles accumulate together, which leads to reduced surface area [68].…”

Providing clean water all over the world at low cost to meet human needs is a big challenge in the current century. As the world strives to keep pace with the increasing demand for clean water as quickly as possible due to the permanent increase in population density and the deterioration of the state of water and its quality in addition to climate changes. The requirement for developing technological innovations incorporated water managing can't be exaggerated. As reached by previous researchers, nanotechnology possesses vast capabilities to improve water treatment and purify it from organic and inorganic pollutants through the safe use of unconventional water sources. This review covers the methods that have been examined both laboratory and commercially in purifying and treating water. This research provides a discussion of the used methods, advantages and their limitations and also covers a study of nanomaterials used as photocatalysts, whether manufactured or under study. This is done by studying and reviewing the chemical and physical properties of these nanomaterials and their applications in treating water pollution.
