“…In their results, the highest glycerol conversion reached 36.96% at 1073 K and the H 2 : CO ratios of syngas were constantly lower than 2.0. Batista et al 63 applied sodium and activated vermiculites as catalysts for glycerol pyrolysis. Their results showed that the use of catalysts increased the conversion of the glycerol pyrolysis process.…”

“…Pharmaceuticals and their metabolites, even at low concentrations, have potentially fatal effects on natural ecosystems and human health (He et al, 2020 ; Keshvadi et al, 2020 ). For example, the occurrence of antibiotics in an aquatic environment can develop antibiotic resistance (Ben et al, 2019 ; Walsh, 2013 ; Wang, Chen, et al, 2020 ). In addition, it has been shown that 58%–68% of consumed common mild analgesic medicine acetaminophen (ACE) is released into the environment, which may transform to N‐acetyl‐p benzoquinone‐imine causing protein denaturation, lipid peroxidation, and DNA damage to organisms (Behravesh et al, 2020 ; Tobajas et al, 2017 ).…”

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.
