: Ever-increasing societal and industrial stress on the environment has made water and wastewater one of the most precious natural resources, as reminded to us in a recent UNESCO report entitled “Wastewater: The Untapped Resource”. Recognizing this trend, numerous countries, and in particular Singapore, have embarked in programs to widely utilize water recycled from wastewater, especially in the industry, which represents about 20% of total water usage, a number expected to increase by 80% by 2030. This is accompanied by growing research activities in order to develop efficient and affordable technologies for industrial water purification, usually consisting of a combination of physico-chemical and biological technologies. Among physico-chemical technologies, electrochemical advanced oxidation processes (EAOPs) show promises because they can break down a variety of hazardous compounds. This seminar will showcase some of the latest advances in terms of EAOP processes, electrode materials and prospective applications. The focus of the seminar will be on electro-Fenton, powered up by superior cathode materials such as graphene, a one-atom-thick fabric of sp2-hybridized carbon atoms arranged in a honeycomb structure that combines extreme mechanical strength, exceptionally high electronic and thermal conductivities. By making use of transparent electrodes such as fluorine-doped tin oxide (FTO) it is further possible to combine the power of photons and electrons in a photoelectron-Fenton process, which can be further be augmented by the phototcatalytics properties of titanium dioxide (TiO2). The seminar will end up with prospective applications for industrial wastewater treatment and a reflexion on scale-up options and how to make EAOPs more cost-effective by coupling them with biological treatment options.
