Investigators from Indian Institute of Technology Release New Data on Photocatalytics

May 30, 2014

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Photocatalytics. According to news reporting originating in Kharagpur, India, by NewsRx journalists, research stated, "A mild, template free protocol has been demonstrated for SnS2 nanoflake formation at the gram level from SnCl2 and thioacetamide (TAA). The SnS2 nanoflakes congregate to nanoflowers and nanoyarns with variable TAA concentrations."

The news reporters obtained a quote from the research from the Indian Institute of Technology, "BET measurements reveal that the synthesized nanomaterials are highly porous having very high surface area, and the nanoflower has higher surface area than the nanoyarn. The synthesized nanomaterial finds application for promoting photoreduction of extremely toxic and lethal Cr(VI) under visible light irradiation due to their porous nature. The nanoflowers photocatalyst is proved to be superior to nanoyarn due to the increased surface area and higher pore volume. It was also inferred that increased pH decreased the reaction rate."

According to the news reporters, the research concluded: "The present result suggests that the morphology-dependent photoreduction of Cr(VI) by SnS2 nanomaterial under visible light exposure will endorse a new technique for harvesting energy and purification of wastewater."
