    • 本研究主要是利用片狀的中孔洞二氧化矽SBA-15作為模板，附載鎳或鈷於SBA-15以及製備雙金屬鉑鎳的中孔洞材料。第一部份中，以熔融態的方式含浸鎳或鈷前驅物於模板的孔洞中，首次發現在真空下加熱可生成金屬態的鎳或鈷奈米顆粒，TEM觀察得知生成的奈米顆粒不僅分散度高，且顆粒小，有利於催化反應的應用。控制實驗條件在較低壓的環境與較慢的升溫速率下，我們利用臨場X光粉末繞射、X光吸收光譜與反射式紅外光譜術來研究此還原反應的機制。第二部份利用SBA-15三維連通的孔洞結構，大量含浸熔融態硝酸鎳、經由氫氣還原金屬，再於移除模板時同時加入氯鉑酸，使其行賈凡尼置換反應，得到鉑鎳合金的奈米結構。我們將此材料應用於電催化氧氣還原反應，實驗結果顯示其電催化活性不如商用之碳附載白金觸媒，可能與金屬奈米顆粒團聚而使暴露出的活性表面積下降有關。

    This study aims to synthesize platinum-nickel mesoporous materials and nickel- or cobalt-loaded catalysts using platelet-like mesoporous SBA-15 silica as hard template. In the first part of the thesis, we found that highly dispersed and small nickel or cobalt nanoparticles could be formed during the thermal treatment in vacuum after impregnation of the molten salt precursor. The materials were characterized by transmission electron microscopy, and the reduction reaction was studied by in-situ X-ray diffraction, X-ray absorption spectroscopy and diffuse reflectance infrared Fourier transform spectroscopy. The second part of the thesis is the preparation of platinum-nickel replica and the electrocatalytic studies for the oxygen reduction reaction. The catalysts were made by impregnating large amount of nickel nitrate into SBA-15, reducing nickel by hydrogen, and finally replacing part of the metallic nickel by platinum by galvanic replacement during the removal of silica by hydrogen fluoride. We found that the two metals formed alloy, but the alloy nanoparticles did not show very good catalytic activity compared to commercial carbon-supported platinum. The results were probably associated to the decrease of exposed active surface area due to the aggregation of alloy nanoparticles during the catalysis.
