ABOUT ME

Dr. Yong Yan’s research spans the fields of Inorganic, Materials and Green Chemistry. His primary focus is on chemical approaches towards capture, storage and conversion sustainable and renewable energy for next generation. A particular emphasis of his research is on design and development of organometallic photoelectrocatalysts, semiconductor photoactive materials and chemical strategies to split water, to convert deleterious carbon dioxide into useful fuels or value-added industrial feedstock, and to obtain sustainable fuels from biomass. His research also explores catalytic reaction mechanism and charge transfer principles in these catalytic pathways.

Dr. Yan joins NJIT in 2016 from NREL (National Renewable Energy Laboratory), the DOE’s primary laboratory for renewable energy and energy efficiency research and development. He has been a postdoctoral researcher at Princeton University, where he developed several electrocatalytic and photoelectrochemical methods to reduce and convert CO2. He obtained his Ph.D. in Chemistry from Tulane University. Dr. Yan has published his research in top journals such as Nature Materials, Nature Energy, Nature Communications, JACS, Chemical Reviews, Inorganic Chemistry etc.

Dr. Yan welcomes graduate students, undergraduate students, postdocs, visiting scholars to work in his laboratory. He encourages students/scholars with background in Chemistry, Materials Science, Chemical Engineer or any related area to contact him through email at yongyan@njit.edu.
