This brief article reports on the fabrication of a prototype novel semiconductor digital device, a microwave-discharge light-emitting diode (MDLED), consisting of an LED and a Schottky barrier diode encapsulated in a quartz ampoule. Coating the surface of this ampoule with TiO2yielded a new photocatalytic TiO2unit (MDLED-TiO2) for use in treating contaminated wastewaters. To the extent that this MDLED-TiO2is driven only by microwave energy, there is no need for electric wires or electrical AC power. As much of the activity of TiO2photocatalyst is enhanced and ultraviolet light emission is generated only by irradiating with microwaves, the MDLED-TiO2affords a simple water treatment device as demonstrated in the present study. The digital device consisted of 14 pieces of MDLED-TiO2units immersed into a model contaminated wastewater toward the decomposition of organic pollutants and sterilization of natural bacteria-contaminated wastewaters performed in an energy-saving manner simply by irradiating the wastewaters with microwaves.Graphical abstract
