The Chemical Catalysis Program in the NSF Division of Chemistry supports Professor Jentoft of the University of Oklahoma in Norman in investigating heterogeneously catalyzed aldol condensation reactions for biomass conversion. This endeavor will be undertaken in collaboration with Karen Wilson at the Cardiff Catalysis Institute in Wales in the UK, whose research will be supported by the Engineering and Physical Sciences Research Council of the UK (EPSRC). Aldol condensation is a key chemical transformation for the conversion of small oxygenates from biomass to fungible fuels because it increases carbon chain length and reduces oxygen content. The PIs will synthesize families of novel materials that differ in acid-base properties, surface hydrophobicity, and morphology. The catalytic performance in aldol condensations using diagnostic and bio-oil-representative reactants will be tested. The acquired knowledge will allow the development of improved solid aldol condensation catalysts that are highly selective and stable in aggressive media.The investigated chemical transformation, aldol condensation, is a key step in the production of second generation bio-fuels and plays a role in several commercial chemical processes. The proposed research will provide the fundamental insight that is necessary to develop novel materials that catalyze this transformation with great efficiency, that is, without excessive energy input or generation of chemical waste. The program will also provide cross-disciplinary scientific and technical training and an international exchange experience for the involved researchers. US students will have the opportunity to perform research and participate in educational activities within the Cardiff Catalysis Institute, a center of excellence in the UK established at Cardiff University.

NSF化学司的化学催化计划支持诺曼俄克拉荷马大学的詹托夫特教授，研究了生物量转化的异质催化aldol凝集反应。这项工作将与英国威尔士的卡迪夫催化学院的卡伦·威尔逊（Karen Wilson）合作，其研究将得到英国工程和物理科学研究委员会（EPSRC）的支持。醛醇凝结是将小氧化物从生物量转化为可及燃料的关键化学转化，因为它会增加碳链长度并减少氧气含量。 PI将合成在酸碱特性，表面疏水性和形态上不同的新型材料家族。 将测试使用诊断和生物油代表反应物的藻类凝结中的催化性能。获得的知识将允许在侵略性培养基中具有高度选择性和稳定的改进的固体醛缩合催化剂的发展。所研究的化学转化Aldol凝结是生产第二代生物燃料的关键步骤，并在几种商业化学过程中起作用。拟议的研究将提供基本的见解，这是开发新型材料，以极大的效率催化这种转变，即没有过多的能量输入或化学废物的产生。该计划还将为参与研究人员提供跨学科的科学和技术培训以及国际交流经验。美国学生将有机会在加的夫大学成立的英国卓越中心加的夫催化学院内进行研究并参加教育活动。
