Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 2,   Pages 180-187 doi: 10.1007/s11783-013-0552-x

Abstract: The debromination ability of Ti/Gr/Pd electrodes was investigated using BDE-47 as a target pollutantThe results indicated that the BDE-47 degradation rates on Ti/Gr/Pd electrodes increased with the negativeAlmost all of the BDE-47 was removed in the debromination reaction on the Ti/Gr/Pd electrode at -0.5-0.5 V, the current efficiency at -0.3 V was higher, because the electrical current acted mostly on BDE-47-47 rather than on water.

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 5,   Pages 867-878 doi: 10.1007/s11783-015-0800-3

Abstract: sepiolite as a supporter was used to investigate the removal kinetics and mechanisms of decabromodiphenyl ether(BDE-209).BDE-209 was rapidly removed by the prepared sepiolite-supported nZVI with a reaction rate that was 5and decreasing pH, and the efficiency decreased with increasing initial BDE-209 concentrations.Adsorption on sepiolite-supported nZVI particles also played a role in the removal of BDE-209.

Frontiers in Energy 2009, Volume 3, Issue 1,   Pages 99-108 doi: 10.1007/s11708-009-0013-1

Abstract: As a developing and the most populous country in the world, China faces major challenges in energy supply and environmental protection. It is of great importance to develop clean and alternative fuels for internal combustion engines. On the basis of researches on DME engine and vehicle at Shanghai Jiaotong University in the last twelve years, fuel injection, combustion, performance and exhaust emissions of DME engine and DME vehicle are introduced in this paper. The results indicate that DME engines can achieve high thermal efficiency and ultra low emissions, and will play a significant role in meeting the energy demand while minimizing environmental impact in China.
