摘    要:为了开发活性高、易回收的光催化剂,采用多步热解法制备了基于泡沫铜的多孔碳均匀负载Cu_(3)P纳米颗粒。在泡沫铜(FC)基底原位生长铜基金属-有机框架晶态材料(Cu-MOF),通过热解处理使得泡沫铜表面覆盖了均匀负载于碳材料的Cu_(2)O/Cu纳米颗粒(Cu_(2)O/Cu@NPC@FC-400)。对该材料进行磷化处理得到目标光催化剂Cu_(3)P@NPC@FC-400。利用X射线粉末衍射(XRD)、傅里叶变换红外光谱(FT-IR)、紫外-可见漫散射光谱(UV-Vis DRS)、X射线光电子能谱(XPS)和扫描电子显微镜(SEM)等表征材料的组成和形貌。以罗丹明B(Rh B)溶液作为模拟废水,探究其光催化性能及机理。结果发现,Cu_(3)P@NPC@FC-400材料对罗丹明B染料具有良好的光催化性能,在3 h内染料去除率可达94%。该材料便于回收,循环利用10次后,光催化活性保持不变。此外,该材料对于含有7种染料的复杂体系也具有优异的光降解性能。该催化剂具有稳定性高、回收简便的优势,可用于处理含有多种染料的废水。

Abstract:To develop the photocatalyst with high activity and easy recyclability, uniformly loaded Cu3P NPs in N-doped porous carbon (NPC) supported by foamy copper (FC) was synthesized through a multi-step calcination method. FC was modified by in-situ growth of copper-based metal-organic framework (Cu-MOF) crystals, which was further calcinated to obtain Cu2O/Cu NPs loaded NPC on the surface of FC (Cu2O/Cu@NPC@FC-400). The desired photocatalyst Cu3P@NPC@FC-400 can be achieved after phosphate treatment. The composition and morphology of the obtained material were characterized by X-ray powder diffraction (PXRD), infrared spectroscopy (IR), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The photocatalytic performance of Cu3P@NPC@FC-400 was studied in the simulated dye wastewater of Rhodamine B (Rh B), and the degradation mechanism was explored as well. It is found that the catalyst exhibits good photocatalytic activity for Rh B with a high dye removal up to 94% within 3 h. The photocatalyst is convenient for recovery, and its activity remains after 10 runs. Moreover, Cu3P@NPC@FC-400 shows excellent photodegradation performance for multi-component wastewater containing 7 dyes. The photocatalyst has the advantage of good stability and easy recovery, which can be used for treating wastewater of various dyes.
Keywords:Metal-organic framework  Foamy copper  Phosphate treatment  Dye  Photocatalytic degradation
