Abstract: A NiB/C catalyst was prepared by a chemical reduction method, and characterized by inductively coupled plasma direct-reading spectrometer (ICP), X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC) techniques. Its catalytic properties were investigated by the reaction of catalytic hydrogenation of nitrobenzene to p-aminophenol (PAP). The characterization result suggests the composition of the amorphous NiB alloy is Ni79.4B20.6, the highest crystallization temperature is 643 K and the alloy particle size is about 30 nm. Nitrobenzene conversion of 80.23%, PAP yield of 11.21% was obtained. The results show that NiB/C catalyst had high catalytic activity on the reaction of catalytic hydrogenation of nitrobenzene.

摘要: 采用化学还原法制备了NiB/C催化剂,利用电感耦合等离子直读光谱(ICP)、X-射线衍射(XRD)、扫描电镜(SEM)和差示扫描量热分析(DSC)等表征手段对其组成、结构、形貌及最高晶化温度进行了分析,对硫酸锌水溶液中硝基苯催化加氢制备对氨基苯酚(PAP)的反应及其催化性能进行了研究。表征结果显示,NiB/C催化剂中非晶态NiB合金的组成为Ni79.4B20.6,最高晶化温度为643K,合金颗粒粒度约为30nm。实验结果表明,硫酸锌溶液中硝基苯催化加氢反应硝基苯转化率为80.23%,对氨基苯酚选择性为11.21%,NiB/C催化剂具有较高的催化加氢活性。
