This paper reviews the recent progress in the preparation of oxide-based and heteroatom-doped particles. Surfactant-templated oxide particles, e.g. silica and titania, are possible candidates for various potential applications such as adsorbents, photocatalysts, and optoelectronic and biological materials. We highlight nanoporous oxides of one element, such as silicon or titanium, and those containing multiple elements, which exhibit properties that are not achieved with individual components. Although the multicomponent nanoporous oxides possess a number of attractive functions, the origin of their properties is hard to determine due to compositional/structural complexity. Particles with a well-defined size and shape are keys for a quantitative and detailed discussion on the unique complex properties of the particles. From this viewpoint, we review the synthesis techniques of the oxide particles, which are functionalized with organic molecules or doped with heteroatoms, the physicochemical properties of the particles and the possibilities for their photofunctional applications as complex systems.
本文综述了氧化物基和杂原子掺杂颗粒制备方面的最新进展。表面活性剂模板化的氧化物颗粒,如二氧化硅和二氧化钛,是吸附剂、光催化剂、光电子和生物材料等各种潜在应用的可能候选材料。我们重点介绍了单一元素的纳米多孔氧化物,如硅或钛,以及那些含有多种元素的纳米多孔氧化物,它们展现出了单个组分无法实现的性能。尽管多组分纳米多孔氧化物具有许多吸引人的功能,但由于其组成/结构的复杂性,很难确定其性能的来源。具有明确尺寸和形状的颗粒是定量和详细讨论颗粒独特复杂性质的关键。从这个角度出发,我们综述了用有机分子功能化或杂原子掺杂的氧化物颗粒的合成技术、颗粒的物理化学性质以及它们作为复杂体系在光功能应用方面的可能性。
