✦ Synopsis

A composite catalyst, in which Fe203 crystallites are deposited on ZnO particles, is found to photogenerate N02-in nitrogen-purged aqueous solution. Hydrogen is evolved concomitantly. 'The effectiveness of the catalyst is attributed to hole transfer from ZnO to Fe,O, and preferential chemisorption of nitrogen at the Fe20, surface. 11 12
