Such reactions could modify the photoelectrochemical properties of the system, as platinum-niobium intermetallics have proven superior to pure platinum for the electrocatalysis of oxygen reduction at elevated temperatures.(32)... [Pg.169]

The reduction of C02 to cellulose occurs in the natural process of photosynthesis. It involves the photoelectrochemical reduction of water to hydrogen and oxygen (Bockris and Tunulli, 1980) and the subsequent formation of CH20 by chemical steps from the released H2 and C02. This natural process gives rise to expectations of the possibilities of fixing atmospheric C02 by artificial photoelectrochemical means. The best would be if one could form methanol photoelectrochemically from the inexhaustible supply of C02 in the air. [Pg.66]

Photoelectrochemical reduction of double bonds also takes place on ZnS sols. For example, efficient photodisproportionation of aldehydes, that is, a photo-Canizzaro reaction, can be observed on suspensions prepared from cold oxygen-free aqueous solutions of ZnS and Na2S (Eq. 29) [169]. [Pg.380]
