Hydrogen (H2) has tremendous potential to serve as a source of clean energy in the future, but the problem of hydrogen storage is still not solved. One approach to overcome this problem is to design materials which can bind hydrogen reversibly within their crystal structure. The present proposal aims at the development of new materials based on sizeselected clusters with the long-term aim to design tailor-made cluster materials for hydrogen storage. The project is divided into three components: (i) Development of experimental capabilities to image size selected clusters deposited on solid substrates, (ii) deposition of cluster materials and control of the various factors that influence their two and three dimensional structure and (iii) characterization of the structure and properties of cluster materials that have the potential to act as hydrogen storage materials. Cluster ions will be generated with a magnetron sputter source and soft-landed on a substrate. Stabilization will be achieved by codeposition of atoms or molecules (e.g., counter ions) or deposition of chemically inert clusters (oxides, carbides, sulphides, hydrides). Monolayers and thin films of cluster deposited materials will be characterized using a combination of in-situ room temperature STM, XPS and TDS.

氢气（H2）作为未来的清洁能源具有巨大的潜力，但氢气的储存问题仍未得到解决。克服这个问题的一种方法是设计能够在其晶体结构内可逆地结合氢的材料。本提案旨在开发基于尺寸选定的簇的新材料，其长期目标是设计用于储氢的量身定制的簇材料。该项目分为三个组成部分：（一）发展实验能力，对沉积在固体基底上的选定大小的团簇进行成像;（二）沉积团簇材料并控制影响其二维和三维结构的各种因素;（三）表征有可能作为储氢材料的团簇材料的结构和特性。利用磁控溅射源产生团簇离子并软着陆在衬底上。稳定化将通过原子或分子（例如，抗衡离子）或化学惰性簇（氧化物、碳化物、硫化物、硫化物）的沉积。单分子层和薄膜的簇沉积材料将使用在原位室温STM，XPS和TDS的组合进行表征。
