Plasma-Photocatalytic Reduction of CO2 by Hybrid-DBD Reactor

Abstract

Plasma-catalytic conversion of mixed CO2 and N2 gas flow over TiO2 photocatalysts was investigated in planar dielectric barrier discharge (DBD) reactor. The synergistic method from the combination of DBD with photocatalysts was proved empirically. Current treatment contributes to a significant enhancement of both CO2 reduction and energy efficiency In order to obtain a solid knowledge of the non-thermal plasma assisted photocatalytic CO2 conversion significant attention shall be paid to the effects of certain external and internal factors. In this regard, thorough outlook on synergistic NTP-catalytic process mechanisms is obtained by means of assessment of both catalytic and NTP characteristics from both practical engineering and theoretical science points of view.

Importance of greenhouse gas decomposition and emissions control is vital in terms of preventing air pollution and consequent risks to human health and environment. Invention and design of technologies directed to utilize atmospheric CO2 and produce value-added chemical closely refers to sustainability concepts and climate change mitigation solutions and also represent huge potential for development.
