Integrate Microwave – UV sources for photocatalytic reaction

F Microwave assisted chemistry is performed using special reactors of dielectric materials placed inside a microwave oven fed with high voltage magnetron sources emitting continuous or pulsed power (ca. 2450 MHz). 1-3

F This technique has been used both in gas-solid system for the photodegradation of many organic molecules (carboxylic acids, aldehydes, phenolic substrates, etc.) adsorbed on TiO2 (T=20÷200°C) and in liquid-solid systems for the photo- degradation of cationic rodhanine-B in aqueous TiO2 dispersion.

F CNR (Italian National Centre of Research) took patents of new devices consisting of microwave-UV integrated electrodeless sources.4
