中文摘要：
采厢原位模板结合化学还原法制备了一维CoPt纳米棒，扫描电子显微镜（SEM）结果表明CoPt纳米棒平均直径为166．3nm，长度在1．045．0μm之间。以CO为探针分子，在固／气界面研究了CoPt纳米棒的红外光学性质，并同本体Pt电极进行对比分析。原位固／气红外光谱结果表明，吸附态CO（COad）在本体Pt上为正常红外吸收，而CoPt纳米棒在GC基底上表现出异常红外效应（AIREs），当CoPt纳米棒负载到高反射率的金基底上可以得到相同的结论，说明CoPt纳米棒表现出异常红外效应是有材料本身的性质，与反射基底无关。论文从固／气界面进一步验证了一维纳米材料的异常红外效应，有助于加深对低维纳米材料异常红外光学性能的理解。
英文摘要：
One-dimensional CoPt nanorods were obtained through the galvanic displacement reaction and chemical reduction. The average diameter of the nanorods was measured to be about 166. 3 nm and the length was mostly between 1.0 and 5.0 μm obtained from the scanning electron microscopy （SEM） measurement. The IR optical properties of the CoPt nanorods and bulk Pt were investigated by in situ FTIR reflection spectroscopy employing CO adsorption as probe reaction at the solid/gas interface. The results of in situ FTIR indicated that bulk Pt shows a normal IR optical property and the CoPt nanorods display abnorrnal infrared effects （AIREs）. The authors can obtain the same results whether the CoPt nanorods were loaded on glassy carbon （C,C） or Au substrates. These results demonstrated that the AIREs were generated mainly by CoPt nanorods and the influence of the substrate materials can be neglected. The study confirmed that one-dimensional CoPt nanorods show AIREs, and throw a new sense to comprehend the anomalous IR properties observed on low-dimensional nanomaterials.
