报告摘要:

As the age of fossil fuels is coming to an end, now more than ever there is the need for more efficient and sustainable renewable energy technologies. This presentation will give an overview on recent developments in solar technologies that aim to address the energy challenge. In particular, nanostructured materials synthesized via the bottom–up approach present an opportunity for future generation low cost manufacturing of devices [1]. We demonstrate various multifunctional materials, namely materials that exhibit more than one functionality, and structure/property relationships in such systems, including new strategies for the synthesis of multifunctional nanoscale materials to be used for applications in photovoltaics, solar hydrogen production, luminescent solar concentrators and other emerging optoelectronic technologies. [2-31].

报告摘要:工业催化中,提高贵金属粒子的抗烧结性能、抑制贵金属粒子在液相催化反应中的流失,是提升催化剂稳定性的关键。在前期工作中,我们课题组选择Ce(OH)CO3为前驱体,通过界面反应,设计了超小Pt粒子内嵌于CeO2纳米管催化剂,发现PtCeO2之间的紧密接触,相互抑制对方的烧结[1]。我们设计Ce(OH)CO3NaOHKMnO4溶液连续发生界面反应,获得了CeO2@Au@CeO2-MnO2三明治空心结构催化剂[2]。此外,我们通过分子筛为硬模板,将PtRu超小粒子内嵌于微介孔结构的碳材料中。此结构极大程度地稳定了贵金属粒子,而且在液相加氢反应中表现出优越的协同效应[3]。最近,我们借助原子层沉积技术(ALD),在CeO2/Pd粒子表面沉积氧化铝,并以氧化铝为牺牲模板,与对苯二甲酸反应,转化为CeO2/Pd@MIL-53(Al)三明治结构催化剂。此结构不仅抑制了Pd粒子的流失,而且MOF壳层材料可以调控液相加氢反应的选择性[4]

报告简介:等离激元(SPR半导体复合纳米结构是催化化学研究的热点之一。经典的等离激元材料纳米金与半导体材料复合后会在界面间产生较强的界面电磁场,从而增强SPR电子在界面上的转移传输能力,有助于催化活性的提高。在经典的Au?TiO2体系中,由于材料本身固有的特点和Au?TiO2相对单一的结合方式,单纯的Au?TiO2界面近场增强效果很难得到更显著的提高。为了解决上述问题,我们提出了回音壁谐振腔增强和反射镜增强SPR吸收两种独特的物理模型,促进入射光的吸收和高效利用。我们在国际上率先提出了在Au?TiO2等离激元光催化体系研究中引入回音壁谐振腔(WGM)的概念,通过对TiO2尺寸的简单变化实现了基于TiO2半导体光学谐振腔对Au?TiO2界面近场和体系光吸收的高效调控,优化了WGM谐振与SPR耦合,产生了WGM?SPR协同作用,从而显著提高了材料界面近场强度、对可见光的吸收和Au热电子产生能力。此外,我们通过在TiO2结构中引入基于纳米Ag反射镜,成功构建了等离激元可见光反射(散射)采集吸收集成体系,大大提高了等离激元催化材料对可见-近红外光的利用程度,提高了催化效率。
