The review summarizes the data on the chemical composition, crystal structure and functional properties of layered rare-earth hydroxides (LRHs), a new family of anion-exchangeable inorganic compounds. Comprehensive information is given on methods for the synthesis of LRHs including hydrothermal and hydrothermal-microwave treatment. Particular attention is paid to the methods of chemical design of hybrid functional materials based on LRHs. Prospects for fabrication of phosphors, heterogeneous catalysts and biomedical materials based on LRHs are analyzed.
The bibliography includes 295 references.
Hydrothermal crystallization pathways of amorphous ceric phosphate gels were found to be determined by the ammonia concentration in a reaction medium. This allows for highly selective hydrothermal synthesis of various finely crystal-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
