Abstract
Description
technical field
[0001] The invention belongs to the technical field of preparation of composite metal oxide films, and in particular provides a method for preparing composite metal oxide films using hydrotalcite-like precursors. Background technique
[0002] Hydrotalcite-like compounds (HTLcs for short) are a kind of composite metal hydroxides (layered double hydroxides for short LDHs) with a layered structure. Because of its special properties in chemistry and structure, hydrotalcites can be directly used as catalysts and catalyst supports. However, more applications of hydrotalcites are as catalyst precursors, that is, they are calcined at a certain temperature to obtain composite metal oxides before application. Hydrotalcite-like composite metal oxides, with their special structures, such as high specific surface area, highly uniform dispersion of divalent and trivalent metals, more alkali centers on the surface, variety of types and excellent catalytic performance , an...
