Findings on Chalcogens Reported by Investigators at City University of New York (On the photoactivity of S-doped nanoporous carbons: Importance of surface chemistry and porosity)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators discuss new findings in Chalcogens. According to news reporting originating from New York City, New York, by NewsRx correspondents, research stated, "This minireview summarizes our recent findings on the photoactivity of S-doped nanoporous carbons. The materials were either synthesized from the sulfur-containing polymers or obtained by heat treatment of commercial carbon with hydrogen sulfide."

Our news editors obtained a quote from the research from the City University of New York, "Their surface was extensively characterized from the points of view of its surface chemistry, porosity, morphology, and electronic properties. The carbons showed enhanced activity towards oxidation of arsine and removal of diben-zothiophenes from model diesel fuel. The latter were oxidized to various oxygen containing intermediates and the cleavage of C-C bonds in aromatic ring was detected when carbon with adsorbed species was exposed to UV or visible light Irradiation resulted in generation of photocurrent in a broad range of wavelength. The presence of sulfur led to the reduction of oxygen and contributed to an increased capacitive performance."

According to the news editors, the research concluded: "We link these effects to the presence of reduced sulfur in the small pores which enhances the dispersive interactions via inducing a positive charge to carbon atoms, to sulfur in oxygenated forms which contribute to Faradaic reactions and increase the polar interactions, and to the hydrophobicity of a surface in small pores where oxygen can be reduced by excited electrons from chromophoric-like sulfur containing groups."
