Dawson, Robert - University of Sheffield

个人简介

Dr. Dawson received his MChem in Chemistry with German from the University of Liverpool in 2006. After a year spent teaching English in Germany, he returned to Liverpool to complete his PhD with Prof. Andrew I. Cooper graduating in 2010 and spending a further two years in the group as a post-doctoral researcher. In 2012 he moved to the Technical University of Berlin as a Marie Curie Intra-European Fellow before returning to the UK in 2014 at the University of Bath. In 2015 he was appointed as a Lecturer in Polymer Chemistry at the University of Sheffield.

研究领域

My research focuses on the synthesis and applications of microporous polymers. These materials are produced from rigid organic building blocks linked together using high yielding chemistries to produce networks. The subsequent removal of the reaction solvent from the rigid framework leaves behind channels into which small molecules can be adsorbed. Previously, I have looked at these materials for applications in hydrogen gas storage, carbon dioxide capture and heterogeneous catalysis. My current research looks at these materials for energy applications; for example reducing energy demand by performing reactions photocatalytically, and utilising CO2 to produce valuable materials.
