The most efficient catalytic reactions are observed in vivo, in enzyme catalysed reactions. Developing biomimetic systems reproducing the physical properties and function of their biological counterpart while improving the stability under a variety of environmental conditions would open numerous applications specifically in the field of renewable energy production. This research proposal aims at understanding the physical nature of the effect of confinement in nanoarchitectures and develop mimic of bioreactors combining the efficiency of the metal nanoclusters as catalyst to the enhanced reactivity due to confinement. This characterization will be followed by the development of tailored unsupported nanoreactors in aqueous environment for applications in fuel cell technology, improving the access of the reactants to the highly active Pt nanocatalysts and artificial photosynthesis with an array of nanoreactors capable of efficient adsorption of the broad range of wavelength of the solar spectrum. The insight gained during this study will not only have a significant impact on the environmentally friendly synthesis of artificial catalysts and their applications but as a model system it will also provide invaluable information on individual factors influencing the efficiency of biological systems inaccessible in vivo.

在酶催化反应中，在体内观察到最有效的催化反应。开发仿生系统，重现其生物学对应物的物理特性和功能，同时在各种环境条件下提高稳定性，这将在可再生能源生产领域开放众多应用。该研究建议旨在理解纳米结构中限制作用的物理性质，并发展模仿生物反应器，从而将金属纳米簇的效率结合在一起，以催化因限制而增强的反应性。这种表征将在水性环境中开发量身定制的无支撑纳米反应器，用于应用燃料电池技术，从而改善了反应物对高度活跃的PT纳米催化剂的访问，并通过一系列能够有效地吸收广阔范围的纳米反应器的人工光合作用太阳光谱的波长。在这项研究中获得的洞察力不仅会对人工催化剂及其应用的环保综合产生重大影响，而且作为模型系统，它还将提供有关影响生物系统效率无法访问的个体因素的宝贵信息。
