The invention relates to an active functional group modified porous graphite phase nitrogen carbide photocatalyst and a preparation method thereof. The technical scheme is as follows: firstly, 30-80wt% inorganic ammonium salt and 20-70wt% nitrogen-containing organic matter are used as raw materials, and the mixture is uniformly mixed to obtain a mixture; and then the mixture is heated at a rate of 2-6°C/min. to 500～600℃, keep the temperature for 2～6h, and cool down to room temperature with the furnace to obtain the sintered material; then wash the sintered material with deionized water for 2 to 3 times, and filter; Drying at ℃ for 20-24 h, the active functional group modified porous graphite phase nitrogen carbide photocatalyst was prepared. The method has the characteristics of simple process, low production cost, resource saving and environmental friendliness; the prepared active functional group modified porous graphite phase nitrogen carbide photocatalyst has large specific surface area, wide light response range and excellent charge transfer performance, and can degrade organic pollution by photocatalysis. It has excellent hydrogen production performance from substances and water splitting. |
