Abstract
Nitrogen oxides (NOx) emission from the combustion of fossil fuels and biomasses is a major global environmental issue. It contributes to acid rain, formation of ground level ozone and yellow smog, which could lead to serious damages to human health and our ecosystem. The selective catalytic reduction (SCR) has been proved to be one of the most effective methods for post combustion denitration (de-NOx). It converts NOx in flue gases to harmless N2 and H2O. Among many low-temperature catalysts reported in the literature, manganese oxide (MnOx) has been proved highly active at low temperature between 75oC and 225oC. However, single MnOx catalysts are unstable, easy to be poisoned and deactivated by SO2 and their operation temperature window is narrow. To overcome the drawbacks of pure MnOx, we modified the TiO2 supported MnOx (MnOx- TiO2232O32O32222Biography

Chen Gao received his Bachelor’s degree of Electrical Engineering and he is pursuing his PhD degree at Xi’an Jiaotong University under the guidance of Prof. Chunming Niu and Associate Prof. Jian-Wen Shi. His research interests are in air pollution control techniques and environmental catalysis for removing NOx at low temperature.
