Investigation of fluorinated surfaces by means of radio-labelled probe molecules

摘要

Acid-base reactions and interactions are at the heart of inorganic fluorine chemistry and are now recognised as forming a very important part of the chemistry,catalytic or non-catalytic,that occurs on inorganic fluorinated surfaces.This review traces the use that has been made of radioactive isotopes,particularly the short-lived beta+ emitter,fluorine-18,and the very long-lived chlorine-36,which is a beta-emitter,to investigate a variety of surface-related phenomena.Attention is concentrated on solid Lewis acids,including aluminium(III) fluoride derivatives,fluorinated gamma-alumina and fluorinated chromia.
