High-porosity high-permeability Nb2O5 ceramic membrane and preparation method thereof
The invention discloses a high-porosity high-permeability Nb2O5 ceramic membrane which is represented by the following general formula: Nb(2-2x-2y)Ta2xTiyO(5-delta), wherein x and y represents mole fractions, 0.1<=x<=0.3, and 0.02<=y<=0.07. Besides, the invention also discloses a preparation method of the high-porosity high-permeability Nb2O5 ceramic membrane. The Nb2O5 ceramic membrane disclosed by the invention simultaneously has high porosity, narrow pore size distribution range, high permeability, high mechanical strength and other performance, and effectively solves the problems that existing ceramic membranes made of aluminum oxide, cordierite, mullite and the like have performance defects, catalyst incompatibility and low catalytic conversion efficiency exist in waste water and waste gas purification treatment and so on, thus bringing major technical breakthrough to the ceramic membrane field, and being beneficial to promote application and development of fine filtration and separation technology in the fields of water treatment, food, medicine, chemical engineering and the like.
