项目摘要

This research project team is positioned as one of the main project "New Protium Function in Sub-Nano Materials", which have serched for new high performance non-equilibrium protium storage materials with nano-structure, nano-composite and amorphous phases as key words for 4 years from 1998 to 2002. This team was organized by four members from Hiroshima University, Nagoya Institute of Technology, Osaka Metropolitan University and Shiga Prefecture University, respectively: Hiroshima University group found new amorphous MgNi alloys with protium storage capacity of 2.5 wt% and a flat plateau in pressure-composition isotherm at room temperature by mechanical milling method. Osaka Prefecture University group have developed the a-MgNi alloys by doping Ti, V and graphite into new metal hydride batteries with high discharge capacity which still leave durability problem to be solved. Nagoya Institute of Technology group developed new nano-composite Mg-Ni-Nd alloy with protium storage capacity of 6-7 wt% and a considerable high reaction rate for hydrogen absorption-desorption at lower temperature than 250。・In 1999 Hiroshima University group found that protium was absorbed up to 7.4 mass % in nano-structural graphite prepared by ball milling in hydrogen atmosphere, and desorbed from 300。・ in which protium occupied two different sites ; the one is a covalent site strongly coupled to carbon atoms and the other is an inter-layer space defective site between the graphene sheets weakly coupled with carbons. To lower the protium desorption temperature, the high pressure milling effect and the catalytic effect on protium storage propertles are now examined as well.

该研究项目团队被定位为主要项目“新的材料中的新蛋白质功能”，该项目已为新的高性能非平衡型储存材料提供了纳米结构，纳米构造，纳米构造和无定形阶段的关键词，从1998年到2002年，该团队由四年成员组织。县大学分别：广岛大学组发现了新的无定形MGNI合金，其蛋白质储存能力为2.5 wt％，并且通过机械铣削方法在室温下压力组分等温线的平坦高原。大阪县大学组通过将Ti，V和石墨掺入具有高排放能力的新金属氢化物电池，开发了A-MGNI合金，这仍然留下耐用性问题。 Nagoya技术研究所开发了新的纳米复合材料MG-NI-ND合金，蛋白质储存能力为6-7 wt％，在低于250的温度下，氢吸收吸收的反应率很高。・ 1999年，Hiroshima University Group在1999年的nano质量中，在nano shopter中吸收了高达7.4个质量的nano syrenter，nano short. Qualter yrystrent y ryter.y ryder.y ryder.哪种蛋白质占据了两个不同的地点；一个是一个共价位点，与碳原子强烈耦合，另一个是一个层间空间缺陷的位点，与碳纤维弱耦合的石墨烯片。为了降低蛋白质脱附温度，现在还检查了高压铣削效果和对蛋白质储存特性的催化作用。
