Shining Light on Sustainability: Nanoengineered Carbon Nitride (CxNy)-based Materials for CO\u2082 Valorization and H\u2082 Generation<\/p>\n
The urgent global demand for sustainable energy and environmental solutions has sparked the search for innovative materials capable of efficient energy conversion and storage. This seminar will present recent advances in nanoengineered carbon nitride (CxNy)-based materials designed for visible-light-driven CO\u2082-to-chemical conversion and green hydrogen production. Moving beyond conventional g\u2011C\u2083N\u2084, I develop advanced C\u2093N\u1d67 variants (g\u2011C\u2083N\u2085, g\u2011C\u2083N\u2086, g\u2011C\u2083N\u2087) with tailored C\/N ratios, engineered through surface functionalization, co-polymerization, defect creation, heterojunction formation, and doping. These strategies enable precise control over electronic properties, bandgap tuning, and charge carrier dynamics. This presentation will demonstrate how nanoengineered materials unlock the visible-light-driven conversion of CO\u2082 into high-value products and green hydrogen, presenting a promising strategy for addressing climate challenges and enabling sustainable chemical technologies. By combining advanced synthesis with spectroscopic insights, this research aims to bridge fundamental understanding and scalable solutions for clean energy and environmental sustainability.<\/p>\n
Short Biography:
\nDr. Pratibha Saini Urhan earned her Ph.D. in Organic Chemistry from the University of Rajasthan, Jaipur, India, in 2021 under the supervision of Prof. Anshu Dandia, where she developed advanced nanomaterials for green organic transformations. She expanded her research experience as a Research Assistant at Ruhr-Universit\u00e4t Bochum, Germany, in Prof. Thomas Ernst M\u00fcller\u2019s group, contributing to international CO\u2082 utilization projects such as SynGas2Ethene and IGSTC-CO2BioFeed. At Friedrich Schiller University Jena, she joined Prof. Wolfgang Weigand\u2019s group on visible-light-driven CO\u2082 conversion and currently works with Prof. Benjamin Dietzek-Ivan\u0161i\u0107, supported by the prestigious DFG-Walter Benjamin Fellowship and ProChancecareer grant, advancing nanoengineered polymeric carbon nitride systems for CO\u2082 upcycling and green hydrogen production. Her research focuses on C\u2093N\u1d67-based nanomaterials and carbon quantum dots (CQDs) for visible-light-driven transformations, aiming to advance sustainable, energy-efficient chemical processes to address global energy and environmental challenges.<\/p>\n","protected":false},"excerpt":{"rendered":"
