摘要: 以氯化铁与二水合氯化铜的投料摩尔比为4∶100、8∶100、12∶100的比例,将氯化铁加入HKUST-1的前体二水合氯化铜和均苯三酸的混合溶液中,在超声波作用下原位合成Fe@HKUST-1负载型材料。用XRD、BET、TGA、SEM对Fe@HKUST-1进行晶体结构、孔径结构、热稳定性、外观形貌进行分析表征,考察了铁负载量对这些性质的影响。将Fe@HKUST-1负载型材料用于苯羟基化反应,实验表明,与HKUST-1相比Fe@HKUST-1负载型材料的活性有所提高。当氯化铁与二水合氯化铜投料的摩尔比为8∶100时,Fe@HKUST-1负载型材料的活性和稳定性在苯羟基化反应中处于较优状态。

Abstract: FeCl3 was mixed with CuCl2·2H2O and benzenetricarboxylic acid,the precursors of HKUST-1,to in situ synthesize Fe@HKUST-1 material under ultrasonic wave. The molar ratios of FeCl3 to CuCl2·2H2O were 4:100,8:100 and 12:100 respectively. The material was then characterized by XRD,BET,TGA and SEM to obtain the data of crystal structure,pore structure,thermal stability and morphology,as well as the influences of loaded iron on the properties of Fe@HKUST-1. Fe@HKUST-1 was applied for the hydroxylation of benzene as catalyst. The results indicated Fe@HKUST-1 had higher catalytic activity than HKUST-1. When the molar ratio of FeCl3 to CuCl2·2H2O was 8:100,the obtained Fe@HKUST-1 showed the best activity and stability in the hydroxylation of benzene.

Key words: benzene, catalyst support, oxidation, metal-organic framework, Fe@HKUST
