摘要

硫化铜纳米材料具有禁带宽度窄的特点，以氯化铜，1-十八烯和油胺为原料，利用高温热解法合成硫化铜纳米晶。所合成的硫化铜利用XRD，TEM，吸收光谱，红外光谱等手段对其进行表征分析。实验结果证明我们所合成的硫化铜纳米晶为Cu_1.1S，形貌为粒子状，并且分散均匀，应用在光催化中，发现在紫外和可见区硫化铜有比较高的光催化活性。用35 W氙灯光照40min后，我们发现利用硫化铜作为催化剂亚甲基蓝的降解率可达到97.8%。

Abstract:

Copper sulfide nanomaterials are characterized by a narrow band gap. Using copper chloride, 1-octadecene and oleylamine as raw materials, copper sulfide nanocrystals are synthesized by high-temperature pyrolysis. The synthesized copper sulfide is characterized and analyzed by XRD, TEM, absorption spectroscopy, infrared spectroscopy and other means. The experimental results prove that the copper sulfide nanocrystals we synthesized are Cu_1.1S, the morphology is particle-like, and the dispersion is uniform. It is used in photocatalysis. It is found that copper sulfide has relatively high photocatalytic activity in the ultraviolet and visible regions. After irradiating with a 35W xenon lamp for 40min, we found that the degradation rate of methylene blue using copper sulfide as a catalyst can reach 97.8%.

Key words: Cu_1.1S NCs infrared spectrum absorption spectrum photocatalysis
