▎ 摘  要

NOVELTY - Preparation of ultrathin porous flaky graphitic carbon nitride photocatalyst involves (s1) weighing 6-7 g urea, fully grinding, placing in transparent quartz crucible, heating at 520-580℃ in muffle furnace at a speed of 2-5℃/minute, heat-preserving for 2-4 hours, and cooling to room temperature along with the furnace, (s2) weighing 6-7 g urea, adding urea into methanol solutions with different volumes, stirring at 50℃ in water bath, uniformly dispersing, pouring into transparent quartz crucible, heating at 520-580℃ in muffle furnace at a speed of 2-5°℃/minute, heat-preserving for 2-4 hours, and cooling to room temperature along with the furnace. USE - Preparation of ultrathin porous flaky graphene carbon nitride photocatalyst used for photocatalytic degradation of rhodamine b (all claimed). ADVANTAGE - The method is economical, simple, and provides catalyst having high photocatalytic degradation activity.
