SBIR Phase I: Combinatorial Synthesis of Electrocatalysts for Ozone Production

这个小企业创新研究第一阶段项目涉及开发一种组合方法，用于发现用于臭氧生成的新型电催化剂。 基于二氧化铅作为阳极电催化剂的电化学臭氧发生器的主要缺点在于，臭氧产生的电流效率仅为10- 15%。 因此，显然需要新的、新颖的阳极电催化剂，其将导致开发新一代电化学臭氧发生器，其臭氧电流效率高达50%，更优选高达90%。 然而，潜在的阳极电催化剂材料的合成和评价通过常规项目，各种金属合金的组合薄膜库将通过使用物理荫罩的真空沉积技术在微孔钛基板上产生。 将通过电化学方法筛选所产生的文库中的臭氧产生。 我们的创新组合筛选工艺用于臭氧生产，将涉及简单的染料漂白/形成过程。新一代电化学臭氧发生器的商业潜力--一次一种化合物的方法是一个漫长的过程。 在这一阶段，具有高电流效率的I是巨大的。 这些新一代臭氧发生器的商业应用将用于水处理，食品加工，废物处理，医疗灭菌，生物污垢控制以及纸张和纸浆漂白。

This Small Business Innovation Research Phase I project deals with the development of a combinatorial method for the discovery of novel electrocatalysts for ozone generation. Electrochemical ozone generators based on lead dioxide as anodic electrocatalyst have a major drawback in that the current efficiency for ozone production is only 10-15%. There is, therefore, clearly a need for new, novel anodic electrocatalysts that will lead to the development of a new generation of electrochemical ozone generators with ozone currentefficiencies of up to 50%, and more preferably, up to 90%. However, synthesis and evaluation of potential anodic electrocatalyst materials by a conventional project, a combinatorial thin film libraries of various metal alloys will be generated on microporous titanium substrates by vacuum deposition techniques using physical shadow masks. The resulting libraries will be screened for ozone production electrochemically. Ourinnovative combinatorial screening process for ozone production will involve simple dyebleaching/formation process.Commercial potential of a new generation of electrochemical ozone generators one-compound-at-a-time approach is a lengthy process. In this Phase I with high current efficiencies is enormous. Commercial applications of these new generation ozone generators will be for water treatment, food processing, waste treatment, medical sterilization, biofouling control, and paper and pulp bleaching.
