Their prototype, presented February 7 in the journal Chem , purified pathogen-rich water in 30 min, killing over Unlike metal-based photocatalytic disinfectants, it achieved this standard without leaving behind secondary pollution or heavy-metal-ion residues, offering a promising alternative to less eco-friendly technologies. Unlike traditional water-purification processes using ultraviolet light, chlorination, or ozone disinfection, photocatalytic methods offer environmentally safe water treatment -- as long as they use the right catalyst. But unfortunately, these greener catalysts tend to be less efficient than metal-based varieties. Widely studied carbon-based catalysts, such as carbon nanotubes and graphene oxide, aren't quite effective enough for practical water-treatment purposes because they fail to produce enough reactive oxygen to overcome pathogens. They utilize nanosheets of graphitic carbon nitride, an ultra-thin two-dimensional material with the right electronic properties to absorb the light and generate reactive oxygen. The removal of the heavy metals depends on the concentration of the heavy metals. if the concentration is too high usually by varying the pH the heavy metals .
