摘要： Bioreactors are crucial in industrial production, where enzyme catalysis typically occurs in water and requires continuous heating, consuming significant energy. This study reports a new type of precisely heated reactor constructed from cellulose and MXene with directional channels and porous inner walls. MXene forms directional channels with cellulose via layered stacking, enabling rapid heat conduction and accurate heat transference to the enzyme catalyst. A temperature control box monitors the reactor's temperature and uses automated heating to reduce energy loss. The reactor's porous structures facilitate faster fluid diffusion, improving the "disturbance" effect. Compared to traditional methods, which heat the entire aqueous solution, this reactor accelerates heat and mass transfer processes, enhancing catalytic performance. The reactor can quickly raise the temperature around the enzyme to 60 degrees C within 100 s and achieve a 98.12 % conversion rate for polydatin within 2 h, significantly higher than the traditional method (89.84 %). The layered MXene reactor structure reduces energy consumption by over 76 %, with total electrical energy consumption of 3.33 Wh compared to 14.33 Wh in traditional methods. This reactor is suitable for continuous-flow catalysis with low energy consumption and excellent cyclic storage stability, offering a new approach for constructing precise temperature-controlled bioreactors.
