Recently, the team of Associate Professor Li Xiang from the School of Energy and Power Engineering and collaborators have made important progress in the field of continuous emissions pollutant control. The relevant research result, under the title of "Plasma-assisted manipulation of vanadia nanoclusters for efficient selective catalytic reduction of NOx", was published online in the journal Nature Communications.

Selective Catalytic Reduction (SCR) is the most effective NOx control technology, and commercial V2O5-WO3/TiO2 catalysts have been used in the field of denitrification in coal-fired power plants for more than 40 years. However, its high operating temperature makes it difficult to apply to low-temperature emissions purification in industrial kilns such as cement and steel. This study presents a plasma-assisted treatment strategy to achieve supported metal oxide nanoclusters from a rapid transformation of monomeric dispersed metal oxides.

Aiming at the forefront of scientific research, Li Xiang's team has been committed to the theory and application of multi-pollutant control of coal-fired emissions and the development of new energy technologies for a long time, and has made a series of progress. The results have been published in Nature Communications, Angewandte Chemie International Edition, and Environmental Science & Technology Technology and other internationally renowned journals.

Yin Yong, a doctoral student at Beihang University, and Luo Bingcheng, Professor at China Agricultural University, are co-first authors of the paper. Li Xiang, Associate professor at Beihang University, Zhu Minghui, Professor at East China University of Science and Technology, and Israel E. Wachs, Professor at Lehigh University, are co-corresponding authors. This work was supported by the National Key Research and Development Program, the National Natural Science Foundation of China, the Energy Frontier Research Center of the U.S. Department of Energy, etc.
