Optical spectra and structure of CdP(sub 4) nanoclusters fabricated by incorporation into zeolite and laser ablation

Article Abstract:

CdP(sub 4) nanoclusters were fabricated by incorporation into the pores of zeolite Na-X and by deposition of the clusters onto a quartz substrate using the laser ablation-evaporation techniques. The results of spectroscopic study and calculation had allowed to assume the creation of (CdP(sub 4))(sub n) clusters with n= 4 in LA experiments and the Raman spectrum of the clusters in zeolite had proved the creation of (CdP(sub 4))(sub 3) and (CdP(sub 4))(sub 4) clusters in zeolite pores.

Influence of fluorine on the catalytic performance of Ti-beta Zeolite

Article Abstract:

The presence of fluorine would be harmful to the catalytic activity of Ti-beta(F) is proved. The catalytic activity of Ti-beta(F) was effectively improved by defluorination through the treatment with NMe4OH.
