摘要

•CrN ultrafiltration membranes with 121 L/m2·h·bar were successfully prepared.•Preparation process by in-situ gas-solid catalytic reaction at 800 °C.•TiO2 additive play an important role in gas-solid reaction of Cr2O3 nanoparticles.•The molecular weight cut off (MWCO) of CrN membranes was around 1740 Da.
