【摘要】 利用生物分子自组装纳米结构基元诱导无机质矿化、定向构筑具有多级结构的无机/有机界面功能体系是生物矿化的重要启示之一1。我们利用具有大量活性羟基及多级孔结构的细菌纤维素为模板,调控反应条件使半导体纳米晶粒围绕纤维素纳米纤维生长,实现一步法构筑柔性复合半导体气凝胶。复合半导体气凝胶具有微纳多级结构、低密度、高孔隙率、高比表面积等优异特性。晶态氧化锌/细菌纤维素复合气凝胶具有优异的日光抑菌性能2。晶态硫化镉/细菌纤维素复合气凝胶具有优异的可见光催化降解有机污染物性能。复合气凝胶块体在抑菌、水与空气净化以及新能源等领域具有良好的应用潜质。更多还原

【Abstract】 Bioinorganic material chemistry provides archetypes of strategies for the organization of hierarchical interfacial materials. The application of the principles and concepts of biomineralization is inspiring a biomimetic approach in the rational organization of advanced materials with hierarchical architectures and intriguing interfacial properties. Here, we show that semiconductor nanocomposite aerogels with hierarchical architectures can be organized by the mediation of bacterial cellulose(BC). The nanocomposite aerogels have characteristic high porosity, low density and high specific surface areas. Zn O/BC and Cd S/BC aerogels exhibit excellent daylight antibacterial properties and visible light photocatalytic properties that could be a result of functional integration of structural hierarchy, multiple interfaces and semiconductive properties.更多还原
