The SiO2-Al2O3-d catalyst was modified with different metal nitrates. It indicates that cadmium nitrate and strontium nitrate could improve the catalytic activity obviously.

用不同种类、不同浓度的金属硝酸盐，对SiO2-Al2O3-d催化剂进行改性研究，发现Cd(NO3)2和Sr(NO3)2改性后，活性和使用寿命较SiO2-Al2O3-d有所提高，而Mg(NO3)2、Ca(NO3)2、Ni(NO3)2改性后的催化剂，活性反而有所降低。

Super-fine K-doped Li2ZrO3 powders were synthesized via the citric acid-ethylene glycol complexing, with the nitrates of lithium, zirconyl and potassium as the materials. Then, the precursor of K-doped Li2ZrO3 and the K-doped Li2ZrO3 powders were characterized by means of TG-DSC, XRD and SEM. Moreover, the thermal decomposition of the gel and the formation of the tetragonal crystalline form were analyzed.
