项目摘要

Abstract#1229645Subramaniam, BalaThe proposed equipment will provide a unique, state of-the-art electron microscopy infrastructure that would allow researchers to directly probe the surface/interfacial properties and surface dynamics of materials at nanometer length scales. These facilities will enable a deeper fundamental understanding essential to developing novel functional materials for catalysis and energy applications.The major users include those from the Center for Environmentally Beneficial Catalysis (CEBC), the Kansas Center for Solar Energy Research (CSER), and their nationwide academic/industry collaborators. Additionally, many other researchers in engineering, geology and biological sciences will benefit from these facilities. CEBC researchers are addressing the major challenges facing the sustainable manufacture of fuels and chemicals from traditional and renewable feedstocks. The design of active, selective and stable catalysts is a key challenge in this regard. Examples of recent innovations include versatile large-pore ordered mesoporous catalyst supports, nanometer size metal catalysts tethered to supports by organic and inorganic anchors that show enhanced activity for a variety of chemical transformations, and bimetallic catalysis for hydrogenolysis of biomass-derived feedstocks. The proposed instrumentation will enable in situ characterizations of the catalytic metal and surface reactant species at nanometer level resolution.

摘要＃1229645SUBRAMANIAM，BALATHE提出的设备将提供独特的状态电子显微镜基础设施，该基础设施将使研究人员能够直接探测纳米长度尺度下材料的表面/界面特性和材料的表面激烈。这些设施将使对开发催化和能源应用的新型功能材料至关重要。主要用户包括来自环境有益催化中心（CEBC）（CEBC），堪萨斯州太阳能研究中心（CSER）及其全国范围的那些用户。学术/行业合作者。此外，许多其他工程，地质和生物科学研究人员将从这些设施中受益。 CEBC的研究人员正在解决传统和可再生原料的可持续生产面临的主要挑战。在这方面，主动，选择性和稳定的催化剂的设计是关键的挑战。最近的创新例子包括多功能大孔有序的介孔催化剂支撑，纳米尺寸的金属催化剂由有机和无机锚定为支撑，显示出各种化学转化的活性，以及用于生物量衍生化的氢化物的双金属催化。所提出的仪器将在纳米水平分辨率下实现催化金属和表面反应物质的原位表征。
