Embodiment 1
[0024] Weigh 5g of phenolic resin and 6g of nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O) according to nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O) The mass ratio of hexamethylenetetramine to 10:1 weighs 0.6g of hexamethylenetetramine, mixes it with 30mL of absolute ethanol, and stirs magnetically at room temperature until the absolute alcohol is completely volatilized to obtain a colloidal solid, and then put The temperature of the vacuum oven was raised to 100° C. to cross-link and cure the thermoplastic phenolic resin for 6 hours. The mixture obtained by dry crosslinking and solidification was put into a carbonization furnace, and the temperature was raised from room temperature to 400 °C at a rate of 1 °C / min under a nitrogen atmosphere, kept for 10 hours, and then cooled to room temperature. 0.5g of carbonized solid particles and 30% H 2 o 2 The mixture is put into a polytetrafluoroethylene hydrothermal kettle, and the filling degree is kept at 70%. The hydrothermal kettle is put i...
Embodiment 2
[0029] Weigh 5g of urea-formaldehyde resin and 8g of nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O), according to nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O) The mass ratio of hexamethylenetetramine to 10:1 weighs 0.8g dimethylaminopropylamine, mixes it with 30mL absolute ethanol, stirs magnetically at room temperature until the absolute ethanol is completely volatilized to obtain a colloidal solid, and then puts it in a vacuum The temperature of the drying oven was raised to 120° C. to cross-link and cure the thermoplastic phenolic resin for 4 hours. Put the dried mixture into a carbonization furnace, and raise the temperature from room temperature to 600 °C at a rate of 1 °C / min under a nitrogen atmosphere, keep it warm for 8 hours, and then cool it down to room temperature. 0.5 g of carbonized solid particles and 20% H 2 o 2 The mixture is put into a polytetrafluoroethylene hydrothermal kettle, and the filling degree is maintained at 80%. The hydrothermal kettle is put into a blast o...
Embodiment 3
[0032] Weigh 5g of phenolic resin and 12g of nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O), according to nickel nitrate (Ni(NO 3 ) 2 ·6H 2 O) The mass ratio of triethylenetetramine to 10:1 weighs 1.2g of triethylenetetramine, mixes it with 30mL of absolute ethanol, stirs magnetically at room temperature until the absolute alcohol is completely volatilized to obtain a colloidal solid, and then puts it into a vacuum oven. The dry box was heated to 150° C. to cross-link and cure the thermoplastic phenolic resin for 3 hours. Put the dried mixture into a carbonization furnace, and raise the temperature from room temperature to 1000 °C at a rate of 1 °C / min under a nitrogen atmosphere, keep it warm for 6 hours, and then cool it down to room temperature. 0.5 g of carbonized solid particles and 10% H 2 o 2 The mixture was put into a polytetrafluoroethylene hydrothermal kettle, and the filling degree was kept at 90%. The hydrothermal kettle was put into a blast oven, and the reaction con...
