Nanostrutured Magnesium-base Composites for High-density Hydrogen Storage

该项目旨在开发用于有效储氢的纳米晶镁基复合材料，克服当前金属氢化物系统的两个主要技术障碍：高充电/放电温度和慢动力学。基于介孔碳和金属纳米颗粒的纳米催化剂将被引入镁中，以增加储存容量并提高低温下的速率。将获得对催化剂的影响以及吸附和解吸机理的基本理解，以优化复合材料。该项目将导致有效和实用的储氢技术，以满足商用燃料电池汽车的目标。

This project aims to develop nanocrstalline magnesium-based composites for effective hydrogen storage, overcoming two main technical barriers of current metal hydride systems: high charging/discharging temperature and slow kinetics. Nanoscale catalysts based on mesoporous carbons and metal nanoparticles will be introduced into the magnesium to increase storage capacity and increase the rate at low temperatures. Fundamental understanding on the effects of catalysts, and adsorption and desorption mechanisms will be obtained to optimise the composite materials. This project will lead to effective and practical technology for hydrogen storage that will meet the target of commercial fuel cell vehicles.
