TITLE: Can cold plasma be a smart catalytic method?


Date: 09:30am, June 27, 2016.



ADDRESSThe 705 meeting room of Building 1


Speaker: Dr. Li Wang

Li Wang is currently working on CO2 utilization at University of Liverpool as a Postdoctoral fellow (2015-2017). She worked as a research associate to conduct research on the direct synthesis of high-purity H2O2 and N-containing organic compounds at Dalian University of Technology (2013-2015). She received her PhD from Dalian University of Technology with prof. Hongchen Guo working on COx-free H2 generation from NH3 (2013). Some research results were published on the International Journals of ACS Catalysis, Chemical Communication, ChemCatChem, Angewandte Chemie, Catalysis Science & Technology, Catalysis Today, International Journal of Hydrogen Energy, etc.



Plasma-chemical and plasma-catalytic processes associated with low-temperature plasma generated by electrical discharge in gas has recently received considerable interest. Non-thermal plasma offers a unique way to initiate chemical reactions in the gas phase as well as liquids, which have potential in chemical, environmental, biological and medical applications.

Low selectivity is a major problem that plasma-chemical process faces. Generally, combination with catalyst not only can improve the selectivity by steering the reactions in the desired direction, but also can dramatically improve the reaction activity, which is usually called as synergistic effects. In this presentation, the mechanism of synergistic effect, i.e. the role of plasma and catalyst in the synergy, will be discussed. In addition, how to selectively activate the desired chemical bond in a molecule by plasma will be discussed as well.

The main contents of the presentation are as follows:

1) The synergy of plasma-catalytic NH3 decomposition for production of H2 energy.

2) H2/O2 plasma reaction for production of high purity H2O2.

3) The selective activation of C-H bond of CH3OH for direct synthesis of ethylene glycol.

4) N-containing compound synthesis from small molecules (CH4, CO, CH3OH, NH3)

5) Plasma-catalytic CO2 utilization
