With the world facing a future of climate change and water scarcity, finding an environmental way to cleanse drinking water is paramount. Researchers in China contend they are working on a method to remove bacteria from water that’s both highly efficient and environmentally sound. By shining ultraviolet light onto a two-dimensional sheet of graphitic carbon nitride, the team’s prototype can purify two-and-a-half gallons of water in one hour, killing virtually all the harmful bacteria present. This technique of photocatalytic disinfection is an alternative to current eco-unfriendly water filtration systems such as chlorination or ozone disinfection.
