For the first time, self-standing microfiltration (MF) hollow fiber membranes were prepared from cellulose triacetate (CTA) via the thermally induced phase separation (TIPS) method. The resultant membranes were compared with counterparts prepared from cellulose diacetate (CDA) and cellulose acetate propionate (CAP). Extensive solvent screening by considering the Hansen solubility parameters of the polymer and solvent, the polymer’s solubility at high temperature, solidification of the polymer solution at low temperature, viscosity, and processability of the polymeric solution, is the most challenging issue for cellulose membrane preparation. Different phase separation mechanisms were identified for CTA, CDA, and CAP polymer solutions prepared using the screened solvents for membrane preparation. CTA solutions in binary organic solvents possessed the appropriate properties for membrane preparation via liquid–liquid phase separation, followed by a solid–liquid phase separation (polymer crystallization) mechanism. For the prepared CTA hollow fiber membranes, the maximum stress was 3–5 times higher than those of the CDA and CAP membranes. The temperature gap between the cloud point and crystallization onset in the polymer solution plays a crucial role in membrane formation. All of the CTA, CDA, and CAP membranes had a very porous bulk structure with a pore size of ∼100 nm or larger, as well as pores several hundred nanometers in size at the inner surface. Using an air gap distance of 0 mm, the appropriate organic solvents mixed in an optimized ratio, and a solvent for cellulose derivatives as the quench bath media, it was possible to obtain a CTA MF hollow fiber membrane with high pure water permeance and notably high rejection of 100 nm silica nanoparticles. It is expected that these membranes can play a great role in pharmaceutical separation.

“…The common membrane matrix includes polyvinylidenefluoride (PVDF), polysulfone (PSf), cellulose acetate (CA), etc. Among these, CA‐based membranes have been widely utilized as support membranes due to the advantages of biodegradability, nontoxicity and low cost . CA‐based photocatalytic membranes also provided sufficient interaction between RhB and the catalyst because of high water flux, hydrophilicity and high porosity …”

Photocatalytic degradation is an effective method for fast removal of dye‐contaminated water. In the present work, a bismuth oxide/zinc sulfide‐cellulose acetate photocatalytic membrane (Bi2O3/ZnS‐CA) is successfully fabricated via the phase‐inversion method with a Bi2O3/ZnS heterojunction as the photocatalyst. The Bi2O3/ZnS‐CA membranes shows high photocatalytic activity in degradation of Rhodamine B (RhB) under visible‐light irradiation due to the Bi2O3/ZnS heterojunction structure contributing to the high efficiency of photogenerated charge separation. The photodegradation efficiency of Bi2O3/ZnS‐CA membrane is significantly enhanced (about 30% improvement) and the photodegradation kinetic is four times faster than that of the Bi2O3‐CA and the ZnS‐CA membranes. Moreover, the Bi2O3/ZnS‐CA membrane exhibits excellent permeation flux (649.7 L m−2 h−1) and high porosity (69.94%). The Bi2O3/ZnS‐CA membrane also shows good adsorption performance of RhB, which could enhance the interaction between RhB and the catalyst. This work provides a new sight to construct highly effective visible‐light‐driven photocatalytic membranes for continuous organic dye treatment.
