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.

项目概要/摘要 每年有 800 万人过早死亡和 5 万亿美元的社会成本与空气有关 根据美国环保局的数据，室内空气质量 (IAQ) 通常会恶化两到五倍。 与室外空气相比，这一点尤其令人担忧，因为我们 90% 的时间都在室内度过。 与空气污染相关的死亡中有 48% 是由不良的 IAQ 造成的， 尤其是挥发性有机化合物 (VOC)，会导致严重的慢性疾病，包括 癌症到肺部疾病，并降低工人的生产力和学生的注意力。 现有技术依赖于污染物捕获、截留，有时还依赖于销毁，但 已知所有这些都存在从解吸到副产品产生和臭氧产生的问题。 Metalmark Innovations, Inc. 正在开发一种先进的混合吸附催化剂空气净化器 系统以有效且无副产品的方式捕获和销毁此类污染物。 净化器依赖于 Metalmark 专有的 3D 纳米结构热催化材料 由于其显着增强的活性、减少的 工作温度和相关的能耗降低，卓越的催化剂 与市售产品相比，稳定性（无纳米颗粒烧结）和成本降低 VOC 被吸附剂模块捕获并间歇性释放至催化剂 为了完全销毁而不释放副产品，在这个第二阶段项目中，我们将采购。 并改进吸附剂材料，设计Metalmark催化剂，优化吸附剂催化剂 系统，通过迭代学习生产出三代空气净化器原型 过程，并使用最终原型进行至少一项试点研究。 SBIR 二期项目中提出的技术挑战将推动这一创新的室内 VOC处理系统走向商业产品，提高室内空气安全 办公室、酒店、学校、家庭和其他室内或机舱内空间。
