Abstract
Nanostructured photocatalysts commonly offered opportunities to solve issues scrutinized with the environmental challenges caused by steep population growth and rapid urbanization. This photocatalyst is a controllable characteristic, which can provide humans with a clean and sustainable ecosystem. Over the last decades, one of the current thriving research focuses on visible-light-driven CeO 2 -based photocatalysts due to their superior characteristics, including unique fluorite-type structure, rigid framework, and facile reducing oxidizing properties of cerium's tetravalent (Ce 4+ ) and trivalent (Ce 3+ ) valence states. Notwithstanding, owing to its inherent wide energy gap, the solar energy utilization efficiency is low, which limits its application in wastewater treatment. Numerous modifications of CeO 2 have been employed to enhance photodegradation performances, such as metals and non-metals doping, adding support materials, and coupling with another semiconductor. Besides, all these doping will form a different heterojunction and show a different way of electron-hole migration. Compared to conventional heterojunction, advanced heterojunction types such as p-n heterojunction, Z–scheme, Schottky junction, and surface plasmon resonance effect exhibit superior performance for degradation owing to their excellent charge carrier separation, and the reaction occurs at a relatively higher redox potential. This review attends to providing deep insights on heterojunction mechanisms and the latest progress on photodegradation of various contaminants in wastewater using CeO 2 -based photocatalysts. Hence, making the CeO 2 photocatalyst more foresee and promising to further development and research. • Recent efforts concerning ceria (CeO 2 ) as a single photocatalyst were reviewed. • Several strategies modifications of CeO 2 -based and heterojunction were reviewed. • The modified CeO 2 -based photocatalyst exhibits high-performance than pure CeO 2 . • The modification of CeO 2 play a vital role in obtaining desired heterojunction. • Several challenges and strategies for development have been proposed.
