The process of heating has influen ce on the crystallinity of CdS. The products were characterized by XRD, SEM, TEM , and the formation mechanism of CdS nanoparticles has also been discussed.展开更多

The calcined sample was characterized by XRD, FTIR, TEM, and Nitrogen ad- sorption-desorption measurement. Results show that the obtained γ-Al2O3 is well-dispersed nanoparticles with par- ticle size of 4 ̄7 nm and the product has nano-pore structure with a narrow pore size distribution of 5 ̄20 nm.展开更多
