“…In order to overcome the strong surface-passivation issue, we introduce a controlled pulsed-electrodeposition (PED) technique to achieve PEI incorporation. The PED technique controls the potential or current swiftly between two different values and it can be used to enhance the passage and distribution of ions, 39,40 and also provide removal/etching in the reverse cycle. 41,42 PED has demonstrated its ability to tune hydrophilicity/hydrophobicity, 43–45 expand the surface area and increase the active sites for electrocatalysis.…”

“…The electrodeposition method is a type of plating by depositing material on a substrate through electrochemical reduction (Hasan et al, 2019) and has been applied in photocatalyst preparation. Reactive materials developed using this method include Au/ZnO film (da Silva et al, 2013), TiO 2 film (Hachisu et al, 2016), and TiO 2 on a silicon wafer surface (Basheer et al, 2020).…”

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.

“…39 The electrodeposition of Mo is limited by the aqueous electrolyte conditions and is performed by inductive co-deposition with an iron group metal. 62,63 Because the Mo composition of the NiMo alloy catalyst produced by electrodeposition reaches saturation of approximately 30% or more, the Mo composition in this study is limited. 64 For Ni-P composition, electrodeposition at room temperature limits the composition of P up to 28%.…”

Summary Proton‐exchange membrane water electrolyzers with active and stable non‐precious catalysts are necessary to produce cheap and efficient hydrogen from water electrolysis. In this study, Ni‐Mo‐P ternary alloy catalysts with a wide composition range are fabricated by electrodeposition. Their activity and stability as hydrogen evolution catalysts are evaluated at the level of both half and single cells. We prove that the morphologies, crystalline structures, and electronic status of the electrodeposited catalysts, which play important roles in the catalytic activity and stability, significantly vary with the compositions of the ternary system. The best performing NiMoP catalyst with an optimal composition exhibited a half‐cell performance of 28 mV overpotential at −10 mA cm−2 and a single‐cell performance of 2 Vcell at 1.87 A cm−2, which is superior to the previously reported NiP‐ and MoP‐based electrolyzers. Due to the addition of corrosion‐resistant P, the NiMoP catalyst exhibited exceptional stability of 3 mV h−1 for 48 hours at 1 A cm−2. As a result, the novel ternary Ni‐Mo‐P catalyst prepared by a simple and low‐cost synthesis method is a strongly promising candidate for non‐precious hydrogen evolution catalysts in proton exchange membrane water electrolyzers.
