BiographyDr. Yatendra S. Chaudhary is Senior Scientist at CSIR-Institute of Minerals & Materials Technology, Bhubaneswar, India and a faculty at the Academy of Scientific and Innovative Research (AcSIR), New Delhi, India. He earned Ph.D. for the research work focused on nanostructured photo-catalysts for solar-driven water splitting in 2004. Subsequently, he moved to Tata Institute of Fundamental Research (TIFR), Mumbai, India, where he carried out research in Materials Chemistry. He designed enzyme-semiconductor based photocatalysts for visible light driven CO2 reduction and H2 production while working at University of Oxford, UK. His research accomplishments in the area of nanomaterial and solar fuel research have brought him many recognitions such as Green Talent-2011 Award from the Federal Ministry of Education and Research (BMBF), Germany, CSIR-Young Scientist Award-2013 in Chemical Sciences section from the Council of Scientific & Industrial Research, India and prestigious Marie Curie Fellowship by the European Union. Dr. Chaudhary has been leading various projects funded by MNRE, CSIR and SERB, New Delhi mainly focusing on the design of artificial photosynthesis devices to produce fuel using solar radiation. He is also actively engaged as reviewer for many RSC and ACS journals and is a member of the editorial board of the Journal of Nanoscience and International Journal of Photoenergy.
The research activities in his group are focused on various facets of colloids and materials chemistry for solar fuel generation. The major focus is on designing the heterostructured photocatalysts with desired morphologies and size as to exploit the advantages associated with nanomaterials (such as quantum confinement effects, surface area), hetero-interface with appropriate energetics and layered structure of semiconductors for efficient solar H2 generation and CO2 reduction to fuels.
