Soot particles from diesel engines are now recognised as carcinogenic and are a major contributor to urban airpollution. Modern cars and trucks are fitted with Diesel Particulate Filter (DPF) systems which are composed ofporous honeycomb structures which trap soot particles and then oxidise them using the exhaust gases whenthere is sufficient heat. This project aims to prove the feasibility of a novel filtering device capable ofdynamically trapping and eliminating soot particles. The device uses a fibrous substrate sandwiched betweenhighly porous ceramic plates. Trapped particles are removed by exposure to high electric current densities. Theproject intends to develop advanced versions of a fibrous substrate where loadings of adsorbed nanoscaleoxidation catalyst facilitate soot removal at lower temperatures. Such advanced substrates will enable thedevelopment of attractive novel alternatives to conventional DPFs which can potentially make major in-roads inproviding effective, lightweight, cost-effective, robust and affordable emissions abatement technology fordeveloping countries with severe urban air quality problems like India.

柴油发动机产生的烟尘颗粒现在被认为是致癌物质，是城市空气污染的主要来源。现代汽车和卡车都装有柴油微粒过滤器（DPF）系统，该系统由多孔蜂窝结构组成，可以捕获烟灰颗粒，然后在有足够热量的情况下使用废气将其氧化。本计画旨在验证一种能动态捕捉及清除碳烟微粒的新型过滤装置的可行性。该装置使用一个纤维衬底夹在高度多孔陶瓷板。捕获的颗粒通过暴露于高电流密度来去除。该项目旨在开发先进的纤维基材，其中吸附纳米氧化催化剂的负载促进在较低温度下的烟灰去除。这种先进的基质将使有吸引力的新型替代传统的DPF的发展，这可能使道路上提供有效的，重量轻，成本效益高，强大的和负担得起的减排技术为发展中国家的严重城市空气质量问题，如印度。
