STUDY OF A TI02 PHOTOCATALYTIC COATING FOR USE IN PLASMA CATALYSIS

摘要

The incorporation of non-thermal plasma (NTP), e.g. corona discharge, in an electrostatic precipitator (ESP) offers a unique way to induce gas phase reactions and remove pollutants, but there are still some disadvantages. Primarily, there is the formation of by-products, like ozone that is a powerful oxi-dans and which upon inhaling could react with the body's internal tissues. Secondly, the occurrence of irreversible deposition on the collector surface results in the decline of removal efficiency. This irreversible deposition can be avoided by improving the discharge mode, including the lay-out of the reactor, by decreasing the frequency and the voltage of the power supply or by the combination of the discharge unit with a catalyst [ 1 ].
