Abstract

A mesoporous nano-magnesium oxide for drug loading and a preparation method thereof are provided. The mesoporous nano-magnesium oxide particle has a particle size of 50 nm to 150 nm, and includes abundant mesoporous structures with a pore size of 2 nm to 20 nm. A surface of the particle has a positive potential in absolute ethanol, with a Zeta potential distribution of 10 mV to 100 mV. The preparation method includes: preparing a mixture of magnesium oxalate and CTAB as a precursor; adding the precursor to a quartz crucible, and placing the quartz crucible in a muffle furnace; calcining at 200℃ for 1 h to make the CTAB in the mixture completely decomposed to produce pure magnesium oxalate; and heating to 530°C, and calcining for 1 h to 6 h to make the magnesium oxalate fully decomposed to produce the nano-magnesium oxide microparticle.
