在过去的十年中，用于能量存储和转换的新材料的合成受到越来越多的关注。这种日益增长的重要性反映了世界人口不断增长对能源的需求不断增长、化石燃料供应有限以及减少二氧化碳排放的迫切需要。机械驱动反应（有效地通过动能的转移和转换）的合成方法可以被视为绿色化学的一个分支。在研磨过程中，材料会受到研磨介质之间以及通过多次碰撞与容器壁之间产生的压力的影响。这些事件会引起机械变形并决定研磨产品的性质。本文重点介绍物理研磨（主要是化学（反应）研磨）在能源相关材料制备中的应用。对于储氢，通过反应研磨制备的复合氢化镁表现出较低的解吸温度和更快的动力学......
The synthesis of new materials for energy storage and conversion has received increasing attention over the last decade. This growing importance reflects the burgeoning energy demand of an escalating world population, the finite supply of fossil fuels and the urgent need to reduce carbon dioxide emissions. Synthetic methods in which reactions are driven mechanically (effectively by the transfer and conversion of kinetic energy) can be considered as a branch of green chemistry. Materials are impacted by pressures that are created between the grinding media and with the container walls through multiple collisions during the milling process. These events induce mechanical deformation and define the nature of the milled products. This article focuses on the application of physical and – principally – chemical (reactive) milling in the preparation of energy-related materials. For hydrogen storage, complex magnesium hydrides prepared by reactive milling exhibit lower desorption temperatures and faster kinetics ...
