Abstract: The two-dimensional metal carbide desalination membrane includes a stack of two-dimensional metal carbide layers. A two-dimensional metal carbide included in the two-dimensional metal carbide layers may have the formula Ti3C2Tx, where T represents a terminating functional group, and x represents a number of the terminating functional groups. The terminating group may be oxygen, hydroxide (OH), fluorine or combinations thereof. The two-dimensional metal carbide desalination membrane includes nano-channels which are selectively permeable to ions. The two-dimensional metal carbide desalination membrane is selectivity permeable to a number of different cations, including Li+, Na+, K+, Mg2+, Ca2+, Ni2+ and Al3+, with counter Cl? anions. Permeation rates depend on the charges of the cations and the ions' hydrated radius, with a critical point around 4.0 ?. The two-dimensional metal carbide desalination membranes can be used as desalination and/or water filtration membranes.

Abstract: The present invention discloses a preparation method of an alumina supported cerium oxide powder material. A cerium organometallic precursor is effectively decomposed into CeO2 nanoparticles at 500-700° C. in an oxygen atmosphere condition by using a chemical vapor deposition method, and the CeO2 nanoparticles are evenly dispersed on an Al2O3 support. The decomposition of the CeO2 precursor is accelerated by changing experimental parameters of reaction between organic materials and oxygen, so as to control the size and microstructure of powder, thereby achieving the preparation and even dispersion of cerium oxide nanoparticles, and avoiding the problem of generation of toxic waste liquor during reaction. The method of the present invention is simple, has a short preparation period, and the cerium oxide nanoparticles prepared are evenly dispersed, can be used as catalytic materials and functional materials, and have a broad application prospect in multiple fields.
