In this study, the metal organic framework MOF [Zn(BDC)(DMF)] crystal was synthesized via ultrasonic irradiation and solvothermal method. The synthesized MOF [Zn(BDC)(DMF)] crystal was characterized by PXRD, FTIR, FESEM-EDX, TGA, UV-DRS and BET. The catalytic activity of MOF [Zn(BDC)(DMF)] was investigated by 4-nitrophenol (4-NP) degradation under direct sunlight irradiation. The influence of various degradation parameters such as initial 4-NP concentration, dosage, pH and H2O2 concentration were investigated. The results indicated that the synthesized MOF [Zn(BDC)(DMF)] exhibited strong photocatalytic activity in the presence of NaBH4 under sunlight irradiation and the reduction of 4-NP to 4-aminophenol (4-AP) completed within 10 min. The study provides the synthesized MOF [Zn(BDC)(DMF)] crystal can be used as a high performance catalyst for the treatment of dyes in wastewater.

超声辅助金属有机骨架的合成在阳光直射下光催化还原4-硝基苯酚

本研究通过超声辐射和溶剂热法合成了金属有机骨架MOF [Zn(BDC)(DMF)]晶体。通过PXRD,FTIR,FESEM-EDX,TGA,UV-DRS和BET对合成的MOF [Zn(BDC)(DMF)]晶体进行了表征。通过在阳光直射下4-硝基苯酚(4-NP)的降解研究了MOF [Zn(BDC)(DMF)]的催化活性。研究了各种降解参数的影响,如初始4-NP浓度,剂量,pH和H 2 O 2浓度。结果表明,合成的MOF [Zn(BDC)(DMF)]在NaBH 4存在下表现出较强的光催化活性。在阳光照射下,在10分钟内将4-NP还原为4-氨基苯酚(4-AP)。该研究提供了合成的MOF [Zn(BDC)(DMF)]晶体可用作高性能催化剂,用于处理废水中的染料。
