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) + Fe2O3-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.
