Abstract:	本計劃將採用兩種方法開發非傳統之奈米結構高比表面積碳材料，其一為以蔗糖等生質物為原料，製作大小介於10至50奈米之球形碳粒子，經過添加硼及微量金屬後，再或以有機聚合物混合包裹成塊材，最後高溫炭化製作具有內部結構之碳氣膠。第二種方法是在酸性的環境下，由碳化合物前驅物-有機模板-矽化物 (carbon precursor-organic templates-silica) 以多成份自組裝 (multi-component assembly) 現象直接合成規則排列的中孔洞碳/矽混成物。然後再將氧化矽以鹼液或氫氟酸去除，製成具有奈米結構之碳材。初期將以1800m2/g之比表面積為基準，最終目標愈達到3000m2/g。此外並將以導入硼元素於碳材中。其方法可以在製作出前述高比表面積碳材料之後，或直接在奈米結構碳材之原料中引入。除此之外，我們將植入會在常溫下將氫分子解離成氫原子之金屬觸媒如鉑、鈀、鎳等，並利用溢出(spillover)效果來提高常溫下氫氣吸附能力。The goal of this proposal is to provide a facile and efficient method for the synthesis of highly ordered mesoporous carbon materials with high surface areas in the range of 1800-3000 cm2/g via a multi-component system containing sucrose, template, and silica under acidic conditions. Various synthesis conditions and compositions will be fine-tuned in order to obtain well-ordered carbon materials with nanostructures. In order to test the hydrogen storage capacity for the mesoporous carbon materials thus obtained, various metal-containing reagents such as boron through either the direct synthesis route or post treatments will be incorporated into the resultant mesoporous carbon materials to enhance their ability of hydrogen storage. In addition, metal catalysts such as Pt, Pd, or Ni will be also incorporated into the system to convert hydrogen molecules into hydrogen atoms to promote the ability of hydrogen storage. 研究期間：9801 ~ 9812
