Recently, professor Yan Naiqiang, professor Qu Zan, and associate professor Xu Haomiao from the School of Environmental Science and Engineering at Shanghai Jiao Tong University has published a research paper entitled "In-situ low-temperature sulfur CVD on metal sulfides with SO2 to realize self-sustained adsorption of mercury" in Nature Communications. This study proposed a sulfur chemical vapor deposition (S-CVD) method for direct transformation of flue gas SO2 to realize the self-sustained adsorption of mercury and break the limitation of Hg0 adsorption capacity.
