Project Summary / Abstract Every year, eight million premature deaths and $5 trillion of societal costs are linked to air pollution. According to the US EPA, indoor air quality (IAQ) is often two to five times worse than outdoor air, which is especially alarming since we spend 90% of our time indoors. In fact, poor IAQ accounts for 48% of air pollution-related deaths. Submicron-scale pollutants, particularly volatile organic compounds (VOCs), cause serious chronic illnesses, ranging from cancer to pulmonary diseases, and reduce worker productivity and student concentration. Existing technologies rely on pollutant capturing, trapping, and sometimes destruction, but are all known to have problems from desorption to byproduct creation and ozone generation. Metalmark Innovations, Inc. is developing an advanced hybrid sorption-catalyst air purification system to capture and destroy such pollutants in an e cient and byproduct-free manner. The air purifier relies on Metalmark’s proprietary 3D nanostructured thermal catalytic materials that are uniquely suited for IAQ applications, due to their significantly enhanced activity, reduced operating temperatures and associated reduction in energy consumption, exceptional catalyst stability (no nanoparticle sintering), and reduced cost compared to their commercially available counterparts. VOCs are captured in a sorbent module and intermittently released to the catalyst for complete destruction without release of byproducts. In this Phase II project, we will source and improve sorbent materials, design the Metalmark catalysts, optimize the sorbent-catalyst system, produce three generations of air purifier prototypes through an iterative learning process, and perform at least one pilot study using the final prototype. Overcoming the technological challenges posed in this SBIR Phase II project will propel this innovative indoor VOC treatment system towards a commercial product for improving the safety of indoor air of o ces, hotels, schools, homes, and other indoor or in-cabin spaces.

项目总结/摘要 每年有800万人过早死亡，5万亿美元的社会成本与空气有关 污染根据美国环保署的数据，室内空气质量（IAQ）通常是美国的两到五倍。 比室外空气更好，这一点尤其令人担忧，因为我们90%的时间都在室内度过。事实上， 室内空气质量差导致的死亡占空气污染相关死亡的48%。亚微米级污染物， 特别是挥发性有机化合物（VOC），会导致严重的慢性疾病， 癌症到肺部疾病，并降低工人的生产力和学生的注意力。 现有的技术依赖于污染物的捕获，捕获，有时甚至是破坏，但 所有已知的都具有从解吸到副产物产生和臭氧产生的问题。 Metalmark创新公司正在开发一种先进的混合吸附-催化空气净化 这是一个以高效和无副产品的方式捕获和销毁此类污染物的系统。空气 净化器依靠Metalmark专有的3D纳米结构热催化材料， 由于其显著增强的活性， 操作温度和相关的能耗降低，特殊的催化剂 稳定性（无纳米颗粒烧结），并且与它们的市售产品相比， 同行VOC被吸附剂模块捕获并间歇地释放到催化剂中 用于完全销毁而不释放副产物。在这个第二阶段的项目中，我们将 改进吸附剂材料，设计Metalmark催化剂，优化吸附催化剂 系统，通过迭代学习产生三代空气净化器原型 处理，并使用最终原型进行至少一次试点研究。克服 SBIR第二阶段项目所带来的技术挑战将推动这一创新的室内 VOC处理系统走向商业化产品，以提高室内空气的安全性， 办公室、酒店、学校、家庭和其它室内或机舱内空间。
