Abstract

Experimental results obtained mainly from observations upon chemical changes produced by illumination of Alcohol Vapour-Metal Oxide interfaces are used to illustrate the distinguishing features of: (A) photoassisted reaction between illuminated metal oxide and gaseous reactant, illustrated byx(CH₃)₂CHOH(g) + Fe₂O₃ + hv → x(CH₃)₂CO(g) + xH₂O(ads) + Fe₂O_3-x (B) true heterogeneously photocatalysed reaction, illustrated by continuing steady-state photooxidation of oxygenated alcohol vapour over ZnO or TiO₂; and (C) endergonic photoconversion capable of continuously evolving high energy products into the gas phase, illustrated by (CH₃)₂CHOH(g) → (CH₃)₂C0 + H₂ over illuminated TiO₂ powder having small Platinum particles or other surface dopant dispersed thereon.
