Process for preparing mesoporous ceria

摘要: Disclosed is a process for preparing mesoporous cerium dioxide, which comprises using soluble salts as source, charging surface active agent, pouring in precipitating agent solution chemical reaction to produce precursor, subjecting precursor filtering, deionized water washing, proceeding ultrasonic wave dispersion, carrying out drying, sintering obtain the CeO2 end product. The obtained product has homogeneous particle-size distribution, high specific 40-140g/cm2, and bore diameter 2-20nm.
