Further study showed that quanta size effect is the reason of ultraviolet absorption and blue shift ofabsorption peak.The prepared nano-ZnO was used in NR-SBR-BR composites, the investigation showed that the vulcanization would be proponed when very small amount of nano-ZnO was added. However, as more nano-ZnO was added and the smaller the particle size was, the shorter the vulcanization time was.

The result s show that the cerium compounds consist of Ce 3/ Ce 4 and Ce 2O 3/ CeO 2 , exist in the form of particles and are excellently dist ributed on the zinc powder subst rate. The capacity-loss of the zinc elect rodes is evidently suppressed while the discharge capacity and cycle life can be markedly improved due to the application of the zinc-based composite powder as negative materials of the silver-zinc bat tery. Especially , discharge capacity of 231. 4 mAh g-1 is still achieved at the 50th cycle for the zinc elect rode using the composite powder .
