Embodiment 1
[0061] Embodiment 1: A method for preparing in-situ N-doped ordered mesoporous carbon with uniform pore size and adjustable chitosan oligosaccharide base, specifically comprising the following steps:
[0062] 1) Preparation of SBA-15 ordered mesoporous silica template: Dissolve P123 in HCl solution and stir evenly in a water bath, then slowly add tetraethyl orthosilicate and continue stirring at this temperature, then Pour the mixture into a hydrothermal tank for hydrothermal reaction, cool it, take it out, wash it, then dry it, and then put the product into a tube furnace to heat up and calcinate to obtain a surfactant-free SBA-15 ordered mesoporous silica template ; wherein the concentration of the HCl solution is 5.5wt%; the temperature of the water bath is 40°C; the mass ratio of P123 to ethyl orthosilicate is 1:2.1, and the stirring time after adding ethyl orthosilicate is 20h; The temperature of the hydrothermal reaction is 100°C, and the time is 12h; the final temperatu...
