A novel supporting material containing benzenesulfonic acid (BSA) groups and ordered mesoporous carbons (OMCs) was first prepared by in situ radical polymerization of 4-styrenesulfonate and isoamyl nitrite under ambient conditions. Then, Pd nanoparticles were deposited on as-produced OMCs (f-OMCs) by the NaBH(4) reduction method. The structure and nature of the resulting composites were characterized by transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and nitrogen adsorption-desorption. The results show that BSA groups are created and the texture and surface chemistry are altered, whereas the ordered porous structure is maintained. The electrocatalytic properties of the Pd/f-OMCs catalysts for formic acid oxidation (HCOOH) have been investigated by cyclic voltammetry and chronoamperometry methods, and excellent electrocatalytic activity can be observed.
一种含有苯磺酸（BSA）基团和有序介孔碳（OMC）的新型支撑材料，首先通过在环境条件下4-苯乙烯磺酸盐与亚硝酸异戊酯的原位自由基聚合反应制备而成。然后，通过硼氢化钠（NaBH₄）还原法将钯纳米颗粒沉积在制备好的OMC（f-OMC）上。通过透射电子显微镜（TEM）、傅里叶变换红外光谱（FTIR）、X射线衍射（XRD）和氮吸附-脱附对所得复合材料的结构和性质进行了表征。结果表明，形成了BSA基团，织构和表面化学性质发生了改变，而有序的多孔结构得以保持。通过循环伏安法和计时电流法研究了Pd/f-OMC催化剂对甲酸氧化（HCOOH）的电催化性能，观察到了优异的电催化活性。
