 Four-channel α-Al2O3 hollow fibers were fabricated by phase inversion and sintering method. Effects of SiO2 doping content on structure and property of hollow fiber were investigated. The results showed that mullite-phase was formed due to the in situ reaction between SiO2 and Al2O3 at 1500 ºC and its content enlarged with the SiO2 doping content. High pure water flux and porosity of hollow fiber were achieved under high SiO2 doping content. When the SiO2 doping content was 20 mol%, the pure water flux and porosity of as-prepared hollow fiber were 18.11 m3·m-2·h-1 and 59.9 %, respectively. Further, the hollow fiber owning a porosity of 59.9 % was used as support to prepare hollow fiber NaA zeolite membrane for pervaporation of 90 wt.% ethanol/water mixture. The permeation flux of the membrane was 21.21 kg·m-2·h-1 at 75 ºC.
