Embodiment 2
[0020] Realize the technical scheme of the present invention, mainly comprise three steps of carbonization, functionalization and chemical synthesis:
[0021] 1) Obtain three-dimensional ordered porous carbon by carbonization: put a dry kenaf stalk with a suitable size and a porous structure in a tube furnace at 900 °C N 2 Calcined in atmosphere for 2 h to obtain three-dimensional ordered porous carbon;
[0022] 2) Obtain three-dimensional ordered porous carbon / Prussian blue nanocomposites by chemical synthesis: (1) Cut the above three-dimensional ordered porous carbon into a suitable size and perform acid treatment to obtain functionalized three-dimensional ordered porous carbon;
[0023] (2) Put 5 mL30 mM FeCl 3 Mix with 0.5 g functionalized three-dimensional ordered porous carbon in the above block, sonicate for 1 h, let FeCl 3 Adsorbed on the surface of functionalized three-dimensional ordered porous carbon material, after that, 5 mL of 30 mM K was added to this mixt...
