act as cocatalysts for AZYB production only when photoexcited
electrons in CdS were effectively transferred to them.
It should be noted that the photocatalytic activity of CdS cores
tended to increase with a decrease in the size, especially in the case
of Rh loading, though bulk CdS particles exhibited only very low
activity. We previously reported similar behaviour for photo-

The size quantization effect is remarkable if the size of the CdS
particle becomes smaller than the exciton Bohr diameter, ca. 6 nm,
and then the electronic energy structure of CdS greatly varies

This fact explains the

enhancement of photocatalytic activities of CdS. The decrease in
particle size caused a negative shift of the potential of the
conduction band edge (ECB) and then enhanced the potential
difference between ECB and the reduction potential of NB,
resulting in acceleration of the rate of electron transfer from
photoexcited CdS nanoparticles to NB.
