The UK's 21st century chemical industry needs to continue to innovate to deliver more efficient, environmentally friendlier and increasingly intensified chemical processes. Many such processes are catalytic in nature. Indeed globally catalysis is playing an increasingly vital role in the innovation of new green chemistry and sustainable production. To maintain its competitive advantage, the UK chemical industry needs new methods for developing catalysts that enhance innovation and reduce cycle times. However, once a catalyst is loaded into a reactor there is little that can be done to control or optimise its performance by external means. Imagine a way of operating catalytic reactors in which the performance of the catalyst could be dramatically modified in a controllable way by external means. Catalyst activity could be optimised and catalyst selectivity could be manipulated in such a way as to 'switch off' unwanted side reactions. Such technology would produce a step change in the global presence of the UK chemical's sector.This work is motivated by the need to supply high catalyst surface areas to catalytic systems undergoing catalytic control through electrochemical promotion. System fabrication must be low cost and construction simple. In particular this proposal intends to build upon recent advances in the understanding of electrochemical promotion and recent advances in the fabrication of controlled-microstructure mixed conducing membranes. For the first time we will be able to electrochemically promote and control the catalytic activity of a highly-dispersed metal catalyst (all previous applications have used low surface area continuous metal electrodes).Recent EC FP6 proposals from the key players in Europe [1] have failed to identify a technically feasible alternative to low catalyst surface areas in systems designed to exploit electrochemical promotion. However, the experimental work and theoretical insights developed in Professor Metcalfe's group [2, 3] are here used to suggest appropriate materials for the electrochemical promotion of a highly dispersed catalyst as well as an operating strategy for catalyst control. The membrane technology required has begun to be developed through EPSRC grants GR/S12197/01 and GR/S12203/01 with Dr K Li of Imperial College.We have begun to seek appropriate protection for the intellectual property associated with the reactor fabrication and the operating strategy and for this reason we ask that this proposal be treated as confidential.

英国21世纪的化学工业需要继续创新，以提供更高效、更环保和越来越强化的化学过程。许多这样的过程本质上是催化的。事实上，全球催化在新的绿色化学和可持续生产的创新中发挥着越来越重要的作用。为了保持其竞争优势，英国化学工业需要新的方法来开发催化剂，以增强创新并缩短循环时间。然而，一旦催化剂被装入反应器，就几乎不能通过外部手段来控制或优化其性能。想象一种操作催化反应器的方法，在这种方法中，催化剂的性能可以通过外部手段以一种可控的方式显著改变。催化剂的活性可以被优化，催化剂的选择性可以被控制，以“关闭”不想要的副反应。这种技术将使英国化学品行业的全球存在发生阶段性变化。这项工作的动机是需要为通过电化学促进进行催化控制的催化系统提供高催化剂表面积。系统制造必须成本低，结构简单。特别是，这项建议旨在建立在理解电化学促进的最新进展和在可控微结构混合导电膜制备方面的最新进展的基础上。我们将第一次能够电化学促进和控制高度分散的金属催化剂的催化活性(所有以前的应用都使用低表面积连续金属电极)。欧洲主要参与者最近提出的EC FP6提案[1]未能在设计用于利用电化学促进的系统中找到技术上可行的替代低催化剂表面积的方案。然而，在梅特卡夫教授的小组[2，3]中发展的实验工作和理论见解在这里被用来建议用于高分散催化剂的电化学促进的适当材料以及用于催化剂控制的操作策略。所需的膜技术已经开始通过EPSRC授予帝国理工学院的GR/S12197/01和GR/S12203/01进行开发。我们已经开始为与反应堆制造和运营策略相关的知识产权寻求适当的保护，因此，我们要求将这项建议视为机密。
