Embodiment Construction
[0017] A kind of zeolite ore template prepares the method for porous carbon, adopts following steps:
[0018] Step 1: Preparation of charcoal / template complex:
[0019] Use zeolite ore as a template and sucrose as a carbon source; put 5g of zeolite ore powder in a beaker, add 20mL of sucrose, deionized water, and sulfuric acid solution in total, shake on a shaker for 2 hours, and filter; put the solid part in air at 100°C Heating under low temperature for 4 hours, then raising the temperature to 150°C and keeping it for 2 hours to polymerize and solidify the sucrose; put the cured product into a tubular atmosphere furnace, and under the protection of nitrogen, raise the temperature to 850°C at a rate of 5°C / min, carbonize for 5 hours, to obtain a carbon / template complex;
[0020] Step 2: Preparation of porous carbon from the carbon / template composite:
[0021] Treat the complex in concentrated hydrofluoric acid for 3 hours, wash it and then treat it with hydrochloric aci...
