Embodiment 1
[0038] Step 1: Wash the pomelo peel of the biomass prefabricated body to remove surface impurities, and cut it into block A with a diameter of 5 mm;
[0039] Step 2: Take 1g of block A and dry at 0°C for 36 hours to obtain block B;
[0040] Step 3: Add 50ml of phosphotungstic acid solution with a concentration of 80g / L and 40ml of ethanol solution to the block B, and magnetically stir for 1.5h to form a mixed solution C;
[0041] Step 4: Transfer the mixed liquid C to a homogeneous reactor lined with polytetrafluoroethylene at a filling ratio of 40%, seal it and put it into a homogeneous reactor, and heat it up from room temperature to Hydrothermal reaction at 180°C for 24 hours, then naturally cooled to room temperature to obtain precursor D;
[0042]Step 5: After washing and filtering the precursor D, mix it evenly according to the mass ratio of precursor D: KOH of 1:3, then move it to a tube atmosphere furnace, and raise the temperature at a rate of 10°C / min under an argon...

[0055] Step 1: Wash the pomelo peel of the biomass prefabricated body to remove surface impurities, and cut it into a block A with a diameter of 3.5 mm;
[0056] Step 2: Take 1g of block A and dry at -20°C for 12 hours to obtain block B;
[0057] Step 3: Add 80ml of phosphotungstic acid solution with a concentration of 12.5g / L and 60ml of ethanol solution to the block B, and magnetically stir for 2.5h to form a mixed solution C;
[0058] Step 4: Transfer the mixed solution C to a homogeneous reactor lined with polytetrafluoroethylene at a filling ratio of 50%, seal it and put it into a homogeneous reactor, and heat it up from room temperature to Hydrothermal reaction at 150°C for 36 hours, then naturally cooled to room temperature to obtain precursor D;
[0059] Step 5: After washing and filtering the precursor D, mix it evenly according to the mass ratio of precursor D:KOH of 0.5:1, then move it to a tube atmosphere furnace, and raise the temperature at 10°C / min under an arg...
Embodiment 3
[0067] Step 1: Wash the pomelo peel of the biomass prefabricated body to remove surface impurities, and cut it into block A with a diameter of 4 mm;
[0068] Step 2: take 1 g of block A and dry at 20°C for 20 hours to obtain block B;
[0069] Step 3: Add 60ml of phosphotungstic acid solution with a concentration of 30g / L and 50ml of ethanol solution to block B, and magnetically stir for 2 hours to form a mixed solution C;
[0070] Step 4: Transfer the mixed solution C to a homogeneous reactor lined with polytetrafluoroethylene at a filling ratio of 45%, seal it and put it into a homogeneous reactor, and heat it up from room temperature to Hydrothermal reaction at 200°C for 12 hours, then naturally cooled to room temperature to obtain precursor D;
[0071] Step 5: After washing and filtering the precursor D, mix it evenly according to the mass ratio of precursor D:KOH of 1:1.5, then move it to a tube atmosphere furnace, and heat it up at 10°C / min under an argon protective atmo...
