在化学系化学催化项目的支持下，麻省理工学院的Yogesh Surendranath正在研究如何利用可再生电力来推动增值燃料和化学品的生产。太阳能和风能等可再生能源将以可持续的方式在满足未来对燃料和化学品的需求方面发挥越来越大的作用。目前，将电能转化为燃料和化学品的技术效率低下，往往需要复杂的分离和处理步骤。该项目旨在开发新的综合战略，通过密切耦合催化和分离来推动化学转化和可再生电力。这项工作将允许研究生和本科生学习可再生能源科学的现代技术，并合作发现新的催化剂和材料。这项研究工作还将与基础广泛的教育推广工作相结合，该工作将采用以修辞学为基础的框架，以促进科学中的互动学习、专业交流和批判性话语。在化学系化学催化计划的支持下，麻省理工学院的约格什·苏伦德拉纳特正在研究如何利用可再生电力来推动增值燃料和化学品的合成。电合成还原反应可分为电化学质子耦合电子转移步骤，以产生活性的表面氢原子，然后通过耦合化学反应使底物氢化。在传统的电催化剂中，化学步骤和电化学步骤被共同定位在相同的界面上，从而防止了对每个步骤的独立控制。这一建议提出了一种新的电催化模式，在这种模式下，键活化的反应环境可以与电化学电荷分离的反应环境完全分离。每一项的独立优化都将从根本上揭示电催化中的新反应性，这些反应性可能构成新的电合成反应的基础。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

With the support of the Chemical Catalysis program in the Division of Chemistry, Yogesh Surendranath of the Massachusetts Institute of Technology is studying how to use renewable electricity to drive the production of value-added fuels and chemicals. Renewable energy sources such as solar and wind are poised to play an increasing role in meeting future demand for fuels and chemicals in a sustainable manner. Currently, technologies for converting electrical energy into fuels and chemicals are inefficient and often require complicated separation and processing steps. This project aims to develop new integrated strategies for driving chemical transformations with renewable electricity by intimately coupling catalysis and separations. The work will allow graduate and undergraduate students to learn the modern techniques of renewable energy science and collaborate to discover new catalysts and materials. The research work will also be integrated with a broad-based educational outreach effort that will employ a rhetoric-based framework to advance interactive learning, professional communication, and critical discourse in science.With the support of the Chemical Catalysis program in the Division of Chemistry, Yogesh Surendranath of the Massachusetts Institute of Technology is studying how to use renewable electricity to drive the synthesis of value-added fuels and chemicals. Electrosynthetic reduction reactions can be bifurcated into electrochemical proton-coupled electron transfer steps to generate reactive surface H-atoms that then hydrogenate substrates via coupled chemical reactions. In conventional electrocatalysts, the chemical and electrochemical steps are co-localized to the same interface preventing independent control of each. This proposal advances a new paradigm for electrocatalysis in which the reaction environment of bond activation can be completely decoupled from that of electrochemical charge separation. Independent optimization of each will expose fundamentally new reactivity in electrocatalysis that could form the bedrock of new electrosynthetic reactions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
