Research Seminar:Dr.Indrajit Shown “Artificial Photosynthesis: Metal Chalcogenide Nanomaterials as a Promising Photocatalyst for CO2 Reduction"
Abstract: World’s geography and climate provide an abundance of solar light and water as free natural resources. We believe that the conversion of CO2 and water into solar fuels via solar light is an approach capable of tackling both energy and environmental issues and addressing future
prospects via efficient, cost-effective solar fuel production. However, efficient implementation of this process, which mimics natural photosynthesis, is technically very challenging, since it involves a combination of processes that can interfere with each other. Last several years, we have introduced several efficient novel nanomaterials and a breakthrough idea to this artificial photosynthesis research. To hunting more efficient photocatalyst system recently the metal chalcogenide based photocatalysts represent an important contribution towards high quantum efficiency (nearly 1%) artificial photosynthesis based on gas phase photocatalytic CO2 reduction under visible light. The details catalyst material synthesis, photocatalytic performance, quantum yield, product selectivity of solar chemicals and recent work will be discussed in the presentation. About the Speaker: Dr. Indrajit Shown is a research associate at the Institute of Atomic and Molecular Sciences (Academia Sinica) Center of Condensed Matter Sciences (National Taiwan University) since 2010. Before he joined IAMS, he worked with Prof. Toyoko Imae as post-doctoral research fellow at Keio University (Japan) & NTUST (Taiwan). He received his Ph.D. from The M. S. University of Baroda in 2008. Recently his work published in Nature Communications. His research interests are in advanced catalytic materials and nanomaterials for energy applications such as CO2 reduction, HER, ORR, supercapacitors and lithium ion batteries.
