摘要： Microfluidic biocatalytic reactors have attracted widespread attention in recent years, but the production cost is generally high, which makes it difficult to meet the needs of large-scale industrial production. Developing a low-cost, green fluid reactor has become an urgent requirement. Here, inspired by the three-dimensional hierarchical structure of natural wood, a cellulose-based bionic microfluidic biocatalytic reactor with vertically aligned channels and a porous inner wall is reported for the continuous fluid catalytic conversion of polydatin to resveratrol. NiO nanoparticles were immobilized on cellulose-based bionic materials as metal arms to adsorb poly-histidine-tagged enzymes to form a stable and efficient biocatalytic reactor. Due to the unidirectionally aligned channels and porous inner wall, the fluid in different channels of the bionic xylem reactor is disturbed through the porous inner wall, which greatly prolongs the residence time for the fluid inside the reactor and increases the probability for contact with the enzyme, improving the internal mass and heat transfer efficiency to achieve high catalytic activity (98.69% treatment efficiency) and excellent stability (maintain a conversion rate of more than 90% within 15 days). Because of the good and stable enzyme immobilization and high catalytic activity of the reactor, it can greatly simplify industrial upstream and downstream production and has broad application prospects for catalytic reactions.
