This article addresses a topic of global interest: the decontamination of water through the action of photocatalysts. Currently, there are persistent pollutants in almost all the world’s water resources that cannot be cleaned with conventional treatments, mainly due to their high chemical stability. For this reason, advanced processes such as photocatalysis are used, where a material known as a photocatalyst is the main actor. However, photocatalytic processes are still far from reaching their maximum efficiency, so the search for alternative methods to improve performance is a current concern, especially considering the use of sunlight and the way in which photocatalyst and contaminated water interact. With the help of the materials chemistry, we tell you how it is that thin layers of such common oxides as iron oxide and zinc oxide could work as a photocatalyst with high potential to decontaminate water more efficiently and with less impact to the environment.
