Yogesh Chandra Sharma is a Professor (HAG) in the Department of Chemistry at the Indian Institute of Technology (IIT) BHU Varanasi, India. He graduated from the Department of Applied Chemistry at the same institute in 1991 and earned his Doctor of Science (DSc) degree in 2010. His research interests include Green Energy, Green Hydrogen Production, Biodiesel Synthesis, Valorization of Biodiesel by-products, and River Health Science. Prof. Sharma has carried out pioneering work on the synthesis and characterization of heterogeneous catalysts for production of biodiesel using first-, second-, third-, and fourth-generation feedstock materials. He designed and fabricated a vertically aligned photobioreactor for the cultivation of microalgae for biodiesel production and used waste materials to produce heterogeneous catalysts. He has also worked on the synthesis of bi-and multi-metallic heterogeneous catalysts. The heterogeneous catalysts produced by his research group have been successfully applied in biodiesel and green hydrogen production. Prof. Sharma is a pioneer in the conceptualization of nanoadsorbents, which have emerged as a groundbreaking material, especially for water purification. Prof. Sharma has done significant work on the synthesis of adsorbents from waste materials, minerals, biomaterials, and other sources for the removal of heavy and toxic metals, dyes, fluorides, nitrates, and phosphates from wastewater. He has also used this technology for drinking water treatment. He has several fruitful national and international collaborations on topics of societal importance. Prof. Sharma is a highly cited author and has published more than 200 research articles, 20 review articles, and several book chapters. He has authored and edited five books on various topics. Prof. Sharma has over 16,700 citations, and he has an h-index of 69 and an i10-index of 173.
