CAS: Electrosynthesis via Electrochemical Hydrogen Permeation

在化学系化学催化项目的支持下，马萨诸塞州理工学院的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在以可持续方式满足未来对燃料和化学品的需求方面将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，并且通常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，用可再生电力驱动化学转化。这项工作将使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。研究工作还将与基础广泛的教育推广工作相结合，该工作将采用一个基于知识的框架，以促进互动学习，专业交流和科学批判性话语。在化学系化学催化计划的支持下，马萨诸塞州的Yogesh Surendranath正在研究如何利用可再生电力来推动价值的合成-添加燃料和化学品。电合成还原反应可以分为电化学质子耦合电子转移步骤，以产生反应性表面H-原子，然后通过耦合化学反应将底物吸附。在常规的电催化剂中，化学和电化学步骤共同定位于同一界面，从而防止各自的独立控制。这一提议提出了一种新的电催化范例，其中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解耦。每一个独立的优化将暴露出电催化的新反应性，这可能形成新的电合成反应的基石。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

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.
