Abstract
Despite the success in the fabrication of various arbitrary-sized one-dimensional architectures, researches still face specific disadvantages of uncontrollable porosity and disordered structures, leading to a deficiency in micro-sized porous for efficient catalytic performance. To improve these limitations, herein, fabricating controllable microstructures based on three-dimensional (3D) printing technology was conducted for catalysis applications. Initially, a multi-channel organized structure printed by silica (SiO2) powder was as the support, onto which different organic functional groups were immobilized. Prior to exploring the catalytic efficiency, different techniques were used to investigate the characterization of 3D-SiO2 systematically. Amongst various immobilized functional groups, the 3D-SiO2 modified with diethylenetriamine showed the best catalytic activity for Knoevenagel condensation reaction. Moreover, the results showed that 3D-SiO2 enhanced catalytic activities of over 90% in only 30 min and could be reused more than ten times with high-performance efficiency while transforming various aldehydes in the presence of malononitrile.
