Hollow fiber membrane can be used as catalytic reactor substrate because of high surface area to volume ratio and high packing density. However, metal catalyst embedded membranes fabrication requires multiple and long-time processing. Also, it still has problems of catalyst leaching. Here, we use single-step solvent transfer-induced phase separation method to prepare bicontinuous interfacially jammed emulsions gels (BIJEL) hollow fiber membrane. Due to a dense layer of silica nanoparticles embedded on the surface of BIJEL membrane, it is easier to impart functionality strongly. In addition, metal catalyst coated membrane is achieved by simply shacking using tannic acid which enables reducing and stabilizing metal nanoparticles on the membrane surface. In order to compare catalytic properties of each structure and figure out best structure for catalytic reaction process, the Suzuki-Miyaira cross-coupling reaction was carried out.
