Abstract

Controlled rate thermal analysis (CRTA) of a series of synthetic aurichalcite (Zn,Cu2+)5(CO3)2(OH)6 with the ratio of Cu/Zn varying from 0.1 to 0.5 proves that the dehydroxylation and carbonate loss occur as non-isothermal and isothermal decompositions. The temperature of the thermal decomposition increases as the Cu/Zn ratio increases. Thermal decomposition of aurichalcite provides a method for preparing mixed oxide catalysts at the molecular level as opposed to the particle level. CRTA technology enables separation of the processes of dehydration, dehydroxylation and decarbonation. X-ray diffraction of the products of the thermal decomposition proved to be a mixture of the oxides ZnO and Cu2O.

8 citations in Web of Science®

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
