Abstract: Co-colloidald CS-TIO2,stabilized with sodium hexameatPhosPhate was PrePared. The charge-transfer state and the free radical intermediates aPPcared during illumination of co-colloidal CdS-TIO2 were studied by using teehniques of fluoresene and spin tarpping-ESR.It is coneluded that some Photorcaetions in co-colloidal system can carry out more efeetively than those insingle colloidal sys-tem.

Key words: ESR, Spin trapping, Fluoreseence, Co-colloid
