Embodiment 1
[0048] This example involves the rapid preparation of highly dispersible HTCS, potassium oxalate non-destructive activation of HTCS to prepare ACS, and a comparative experiment, the specific steps include:
[0049] Sample (1): Dissolve 6 parts by mass of sucrose and 1 part by mass of APS in 40 parts by volume of water, then transfer the mixed solution to 80 parts by volume of a stainless steel hydrothermal kettle lined with polytetrafluoroethylene, and place it in a hot air oven The temperature was raised to 75°C for 2 hours, and then heated to 180°C for 2 hours. The reaction solution was filtered, the filter cake was washed three times with water and ethanol, and the filter cake was dried at 80°C in a hot air oven for 8 hours to obtain 1.62 parts by mass of black fluffy powder. , named Csuc-APS(2h).
[0050] Sample (2): Dissolve 6 parts by mass of sucrose in 40 parts by volume of water, then transfer the solution to 80 parts by volume of a stainless steel hydrothermal kettle ...
Embodiment 2
[0054] This example involves the rapid preparation of highly dispersible HTCS, potassium oxalate non-destructive activation of HTCS to prepare ACS, and a comparative experiment, the specific steps include:
[0055] Sample (1): Dissolve 6 parts by mass of sucrose and 1 part by mass of APS in 40 parts by volume of water, then add 0.1M FeSO 4 0.5 parts by volume of the solution, and then transfer the mixed solution to 80 parts by volume of a stainless steel hydrothermal kettle lined with polytetrafluoroethylene, place it in an oven and heat it up to 75°C and keep it warm for 4h, then heat it up to 180°C and keep it warm for 1h. The reaction solution was filtered, the filter cake was washed three times with water and ethanol respectively, and the filter cake was baked in a hot air oven at 80° C. for 8 hours to obtain 1.86 parts by mass of a black fluffy powder, named Csuc-APS (Fe 2+ )(1h).
[0056] Sample (2): Dissolve 6 parts by mass of sucrose in 40 parts by volume of water, th...
Embodiment 3
[0061] This example involves the rapid preparation of highly dispersible HTCS, potassium oxalate non-destructive activation of HTCS to prepare ACS, and a comparative experiment, the specific steps include:
[0062] Sample (1): Dissolve 6 parts by mass of sucrose and 5 parts by mass of APS in 40 parts by volume of water, then add 0.1M FeSO 4 solution 1.5mL, and then transfer the mixed solution into 80 parts by volume of a stainless steel hydrothermal kettle lined with polytetrafluoroethylene, place it in an oven and raise the temperature to 75°C and keep it warm for 4h, then raise the temperature to 185°C and keep it warm for 2h. The liquid was filtered, the filter cake was washed three times with water and ethanol respectively, and the filter cake was dried in a hot air oven at 80°C for 8h to obtain 2.12 parts by mass of a black fluffy powder, which was named as Csuc-APS(Fe 2+ )(2h);
[0063] Sample (2): Dissolve 6 parts by mass of sucrose in 40 parts by volume of water, then...
