Catalysts are chemical substances that provide an alternative pathway for chemical reactions to occur that is less energy-intensive and more rapid than the pathway taken without the catalyst present. Some catalysts are difficult to recover when the catalytic process is completed. Attaching them to a solid surface improves their recoverability and gives an additional route to tailor their catalytic ability. Dr. Gary F. Moore and his team of researchers at Arizona State University are developing innovative ways to create and assemble polymeric surface coatings that attach molecular catalysts to solids that are useful for solar energy capture and storage. The catalyst-polymer construct stabilizes the component materials and enhances their utility for generating fuels and other value-added chemical products with minimal environmental impact, giving broader societal impacts to his research. Dr. Moore is active in outreach programs that engage students in the science, technology, engineering, and mathematics (STEM) disciplines using topics that draw on advancements made in his research in chemical catalysis and energy science. These activities include research opportunities in Dr. Moore's laboratory to promote the education of under-served students from local high schools and Native American tribes. His integration of research, education, and societal impact broadens student participation in science, and is a major component of this CAREER grant.With funding from the Chemical Catalysis Program of the Chemistry Division, Dr. Gary F. Moore is pioneering novel synthetic methodologies to immobilize molecular redox catalysts onto semi-conducting and conducting solids while retaining or enhancing their activity using surface-grafted polymers as a soft scaffold. In these extended polymer matrices, key features of biological enzymes are incorporated into the catalyst design and include extended ligation spheres, channels for substrate delivery and product removal, and regeneration strategies for spent catalysts. The functionality of these materials is under investigation for (photo)electrochemically activation of a range of industrially relevant redox couples, including the H+/H2, CO2/CO and N2/NH3 transformations, and the catalyst activity is examined using (photo)electrochemical characterization techniques. Surface-sensitive characterization methods including grazing angle Fourier transform infrared and X-ray photoelectron spectroscopies. Broader societal impact of the research results from improved catalyst designs for solar generation of fuels and other value-added chemical products. Dr. Moore is actively engaged in STEM outreach programs that provide mentorship and research opportunities to traditionally under-served students from local high schools and Native American tribes, encouraging promising students early in their academic endeavors and inspiring their pursuit of STEM careers. His integration of research, education, and societal impact broadens student participation in science, and is a major component of this CAREER grant.

催化剂是一种化学物质，它为化学反应的发生提供了一种替代途径，与不存在催化剂的途径相比，它的能量密集程度更低，速度更快。有些催化剂在催化过程完成后很难回收。 将它们附着在固体表面上提高了它们的可回收性，并提供了一种额外的途径来调整它们的催化能力。加里·F博士亚利桑那州立大学的摩尔和他的研究小组正在开发创新的方法来制造和组装聚合物表面涂层，将分子催化剂附着在固体上，用于太阳能的捕获和储存。催化剂聚合物结构稳定了组分材料，并提高了它们在产生燃料和其他增值化学产品方面的效用，同时对环境的影响最小，为他的研究带来了更广泛的社会影响。摩尔是积极的外展计划，吸引学生在科学，技术，工程和数学（干）学科使用的主题，借鉴了他在化学催化和能源科学的研究取得的进展。这些活动包括在摩尔博士的实验室进行研究的机会，以促进当地高中和美洲土著部落中得不到充分服务的学生的教育。他的研究，教育和社会影响的整合扩大了学生在科学的参与，是这个职业生涯补助金的主要组成部分。摩尔是开创性的新型合成方法，将分子氧化还原催化剂固定在半导电和导电固体上，同时使用表面接枝聚合物作为软支架来保持或增强其活性。 在这些扩展的聚合物基质中，生物酶的关键特征被并入催化剂设计中，并且包括扩展的连接球、用于底物递送和产物去除的通道以及用于废催化剂的再生策略。这些材料的功能性正在研究一系列工业相关氧化还原对的（光）电化学活化，包括H+/H2，CO2/CO和N2/NH3转化，并使用（光）电化学表征技术检查催化剂活性。表面敏感的表征方法，包括掠射角傅里叶变换红外和X射线光电子能谱。改进催化剂设计的研究成果对太阳能发电燃料和其他增值化学产品产生更广泛的社会影响。 摩尔积极参与STEM外展计划，为当地高中和美洲原住民部落传统上服务不足的学生提供指导和研究机会，鼓励有前途的学生在学术努力的早期，并激励他们追求STEM职业。他的研究，教育和社会影响的整合扩大了学生在科学的参与，是这个职业生涯补助金的主要组成部分。
