Embodiment 1
[0062](1) Add 2g of reduced iron powder and 30mL of 2mol / L nitric acid solution into the reactor, stir to fully dissolve; then apply a 0.4T magnetic field at the bottom of the reactor, and slowly inject ammonia gas into the reactor Mixed gas with air (the volume ratio of ammonia gas to air is 8:1); when the pH value reaches 10, stop feeding the gas, gradually raise the temperature to 70°C, seal the reactor, and keep it for 3 hours; the obtained product is washed and vacuum-dried , get Fe 3 o 4 Nano flower-like nanoparticles;
[0063] (2) Weigh 0.1gFe 3 o 4 Nano flower-like particles, dispersed in 10mL aqueous solution containing 0.4g polyvinyl alcohol and sonicated for 20 minutes; respectively added 4.5g p-toluenesulfonic acid and 0.035g galactose, stirred vigorously and mixed for 30 minutes; the mixture was transferred to an autoclave In the process, react at 100°C for 1 hour, then gradually raise the temperature to 185°C, and carbonize for 8 hours; after cooling, extract...
