项目摘要

Quality of indoor air is strongly affected by volatile organic compounds (VOCs), which pose a serious healthrisk even at very low concentrations (usually at part-per-billion, ppb, range). Solid-state chemical sensors thatare typically made of highly engineered inexpensive materials are quite sensitive to VOCs and are easy tofabricate. However, the biggest challenges are selectivity to a particular target gas or cross-sensitivity.In collaboration with our industry partner, Alphatron technology, we plan to develop a novel nanotechnologybased intelligent sensor systems for selective and sensitive monitoring of particular VOCs fordemand-controlled ventilation in indoor environments. This will be achieved by employing novelnanomaterials in well-defined structures, activated by thermal and radiation energy as well as operating sensorsystems in optimized conditions for enhanced performance.Two different classes of semiconductor gas-sensing material will be studied: 1) The material developed byAlphatron technology, activated by thermal energy, and 2) The new sensing materials synthesized by UBCresearch team activated by UV radiation emitted from LEDs.Sensor systems developed in this research combined with a comprehensive user interface for indoor air qualityis expected to find a considerable market in North America and beyond, especially if the systems are intuitiveand available at low cost.

室内空气质量受到挥发性有机化合物 (VOC) 的强烈影响，即使浓度非常低（通常为十亿分之一，ppb 范围），也会造成严重的健康风险。固态化学传感器通常由高度工程化的廉价材料制成，对 VOC 非常敏感，并且易于制造。然而，最大的挑战是对特定目标气体的选择性或交叉敏感性。通过与我们的行业合作伙伴 Alphatron technology 合作，我们计划开发一种基于纳米技术的新型智能传感器系统，用于选择性和灵敏地监测特定 VOC，以实现室内环境中的需求控制通风。这将通过采用结构明确的新型纳米材料、由热能和辐射能激活以及在优化条件下操作传感器系统以增强性能来实现。将研究两种不同类别的半导体气敏材料：1) 由 Alphatron 技术开发的材料，由热能激活，2) 由 UBC 研究团队合成的由发射的紫外线辐射激活的新型传感材料这项研究中开发的传感器系统与室内空气质量综合用户界面相结合，预计将在北美及其他地区找到相当大的市场，特别是如果系统直观且成本低廉的话。
