这个小企业创新研究一期项目将研究利用氧化还原聚合物电极通过氧化还原催化剂的电化学再生来合成过氧化氢。过氧化氢是一种以水为反应产物的清洁氧化剂。因此，在许多行业中，它是环境可接受的。北美的过氧化物市场预计在未来五年内将增长10%。现有的工厂正在满负荷运转，需要新的工厂来满足未来的需求。利用水系统取代商业蒽醌工艺（使用非水溶剂）的新技术是扩大的理想选择。本项目涉及利用氧化还原聚合物催化剂，通过电化学和化学反应的结合，在一个反应步骤中合成过氧化氢。第一阶段的建议工作包括制备一种稳定的氧化还原聚合物催化剂，用于从氧气或空气和水中生产过氧化氢。氧化还原聚合物将使用红外光谱和电化学技术（伏安法，旋转圆盘实验）进行表征。第一阶段将使用一个简单设计的实验室单元来演示该过程并测量过氧化氢的生产效率。现有的工厂正在满负荷运转，需要新的工厂来满足未来对过氧化氢生产的需求。利用水系统取代商业蒽醌工艺（使用非水溶剂）的新技术是扩大的理想选择。第一阶段研究的结果将导致现场和中央制造设施的新工艺。

9860838 This Small Business Innovation Research Phase I project will investigate the use of redox polymer electrodes for the synthesis of hydrogen peroxide through electrochemical regeneration of redox catalyst. Hydrogen peroxide is a clean oxidant with water as its reaction product. It is therefore environmentally acceptable in many industries. The market for peroxide in North America is expected to grow by 10% over the next five years. The existing plants are operating to their full capacity and new plants are needed to meet future demand. New technology using aqueous system that can replace the commercial anthraquinone process (using non-aqueous solvents) is desirable for the expansion. This project involves the use of redox polymer catalysts for synthesis of hydrogen peroxide in a single reaction step through combined electrochemical and chemical reactions. The Phase I proposal work includes preparation of a stable redox polymer catalyst for the production of hydrogen peroxide from oxygen or air and water. Redox polymers will be characterized using IR and electrochemical techniques (voltammetry, rotating disc experiments). A laboratory cell of simple design will be operated in the Phase I to demonstrate the process and measure peroxide production efficiencies. The existing plants are operating to their full capacity and new plants are needed to meet future demand for production of peroxide. New technology using aqueous system that can replace the commercial anthraquinone process (using non-aqueous solvents) is desirable for the expansion. The outcome of the Phase I research would result in new process for both on site and central manufacturing facility.
