摘要:

采用NaBH₄还原法将不同原子比的铂镍负载于CMK-5(由SBA-15模板所得的碳载体)表面. X射线衍射(XRD)和X射线光电子能谱(XPS)测试结果表明, 所得催化剂是以铂镍合金的形式存在, 相对于Pt/CMK-5而言, 这种合金化的催化剂中Pt表现出更多的金属态. 电化学测试结果显示, 在催化剂中主要以化合态存在的镍(包括NiO、Ni(OH)₂和NiOOH)可能更有利于甲醇的吸附和氧化产物从催化剂表面的脱附. 另外, 从循环伏安测试结果可知, Pt-Ni/CMK-5 (5:1)(原子比)具有较大的比表面活性, 其电化学活性面积高达63.9 m²·g^-1, 且与Pt/CMK-5相比抗CO中毒能力有明显改善.

Abstract:

Pt-Ni alloy catalysts with different atomic ratios were deposited on CMK-5 (carbon replicated from SBA-15 silica) by NaBH₄ reduction. X-ray diffraction (XRD) suggests alloy formation between Pt and Ni. X-ray photoelectron spectroscopy (XPS) shows that Pt-Ni/CMK-5 (5:1) has more detectable oxidized Ni. More metallic Pt is present on Pt-Ni/CMK-5 (5:1) (atomic ratio) than on Pt/CMK-5. Oxidized Ni species, such as NiO, Ni(OH)₂， and NiOOH, favor the adsorption of methanol and the dissociation of methanol from the surface of Pt. Cyclic voltammetry shows that Pt-Ni/CMK-5 (5:1) has the highest specific activity among the as-made catalysts and its electrochemical active area is 63.9 m²·g^-1. It has more resistance to CO poisoning than Pt/CMK-5.
