DESCRIPTION:Prof. Christian Reece\,\nThe Rowland Institute at Harvard\,\nR
 ice University\, Cambridge\, MA\, USA\nAbstract: The complex and dynamic n
 ature of heterogenous catalytic materials means that even when using high-
 resolution spectroscopic methods (e.g.\, XAS\, TEM) identification of “a
 ctive sites” on “technical catalysts” is fraught with difficulties. 
 To circumvent these hurdles\, we have developed a method where intrinsic k
 inetics is used to probe active sites. As the rate at which a species reac
 ts on a catalytic surface is defined by the local environment in which tha
 t species is adsorbed\, an intrinsic rate constant (i.e.\, one that has be
 en isolated from thermal and mass transfer constraints) of a chemical tran
 sformation is an accurate descriptor of the “active site” on the catal
 yst surface. In this work\, we demonstrate how intrinsic kinetics can be u
 sed to quantify and characterise active sites\, and how this leads to new 
 discoveries on structure-function relationships.\n\n\nBio: Christian Reece
  earned his BSc in Chemistry from the University of Bath and his PhD in Ch
 emistry from Cardiff University\, before joining Harvard University as a p
 ostdoctoral researcher with Robert Madix. He is currently a Rowland Fellow
  at the Rowland Institute at Harvard and is an incoming Assistant Professo
 r of Chemistry at Rice University. His research focuses on controlling cat
 alytic systems to gain fundamental insight into the relationship between s
 tructure and function.\n\n\n\n
