1. A preparation method of lotus leaf derived biochar loaded with zeolite-imidazolate framework-67 (ZIF-67), comprising:
drying a lotus leaf at a temperature of 50-90 Celsius degree (° C.) for 1-5 hours (h) to remove moisture therein to thus obtain a dried lotus leaf, and cutting the dried lotus leaf to obtain a pretreated lotus leaf carrier; and
adding the pretreated lotus leaf carrier and ZIF-67 to methanol as solvent, to obtain a solution, performing an ultrasonic dispersion process on the solution, standing the solution after performing the ultrasonic dispersion process to perform a self-assembly reaction to thus obtain a reacted solution, and drying the reacted solution to obtain the lotus leaf derived biochar loaded with the ZIF-67, wherein a drying temperature for drying the reacted solution is 200-220° C., and a drying time for drying the reacted solution is 4-9 h.
