STTR Phase I: Graphene Based NOx Detector

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。该小型企业技术转让第一阶段项目将开发一种基于石墨烯的低成本、高灵敏度氮氧化物 (NOx) 检测器。气体探测器，例如目前提出的氮氧化物传感器，将是基于石墨烯的设备的第一个商业应用。石墨烯薄膜有可能检测到吸附气体的单个分子。有效、廉价的氮氧化物传感器的可用性将使汽车和卡车应用中的发动机状况闭环控制成为可能，从而使制造商能够同时优化车辆燃油经济性、废气排放和性能。这些氮氧化物传感器还将支持一系列其他工业和发电应用的排放监测。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Small Business Technology Transfer Phase I project will develop a low-cost, high sensitivity detector for nitrogen oxides (NOx) based on graphene. Gas detectors, such as the presently proposed NOx sensor, will be the first commercial application for graphene based devices. Graphene films can potentially detect down to a single molecule of an adsorbed gas.The availability of an effective, inexpensive NOx sensor would enable closed-loop control of engine conditions in auto and truck applications, allowing the manufacturers to simultaneously optimize vehicle fuel economy, exhaust emissions and performance. These NOx sensors will also enable emissions monitoring for a range of other industrial and power generation applications.
