Improvement in indoor environmental quality is important as most people spend over 90 percent of their time indoors, especially the young, the elderly, and people with chronic illnesses. The temperature and humidity conditions in typical indoor environment are inductive to the growth of bacteria, molds, etc. Indoor air quality improvement in conventional buildings is primarily via the ventilation system, whose operation incurs an associated energy budget. This research will advance the understanding of the photocatalytic properties of titanium oxide nanofiber composite to be use for autogenously clean of the building environment. The autogenous cleaning function in air quality improvement and airborne contaminant removal will be driven by the ambient light and further augmented with nanoporous structure of the nanofiber. The material will improve the aesthetic appearance of building structures and can serve a variety of decoration purpose. The material design will be tailored towards green and upscalable production. This innovation will demonstrate the design of novel material and product to improve the quality of the indoor environment, which can lead to significant improvement in the public life and reduce the health care cost. Such innovation will expand the horizon of the multifunctional building envelope. It will also train students through research projects that increase the interdisciplinary competencies of young researchers in the areas of design and testing of innovative materials, green manufacturing, and smart building envelope, etc.The objective of this research is to optimize the design of an innovative multifunctional photocatalytic fiber composite through microstructuring and photoactivity chemical tuning. The hypotheses of this research are 1) a green manufacturing procedure for non-metal doped titanium oxide nanomaterials can be implemented to extend the activation spectrum from ultraviolet to the visible and infrared ranges; 2) high efficiency photocatalytic air cleaning can be achieved via composite nanofiber structure. The project tasks include: 1) develop economical and effective syntheses manufacturing technology for non-metal doped titanium oxide nanomaterials with extended activation spectrum in the visible and/or near-infrared ranges; 2) characterize the photocatalytic efficiency of non-metal doped titanium oxide; 3) optimize the design of broadband photocatalytic nanofiber composite mat considering multifunctional design matrix and methods of application; and 4) quantify and fine-tune the photocatalytic efficiency and durability of the nanofiber mat.

室内环境质量的改善很重要，因为大多数人在室内花费超过90％的时间，尤其是年轻人，老年人和患有慢性病的人。典型的室内环境中的温度和湿度条件对细菌，模具等的生长感应。常规建筑物的室内空气质量改善主要是通过通风系统，该通风系统会产生相关的能源预算。 这项研究将提高对氧化钛纳米纤维复合材料的光催化特性的理解，用于自动清洁建筑环境。空气质量改善和空气污染物清除的自动清洁功能将由环境光驱动，并通过纳米纤维的纳米方面结构进一步增强。该材料将改善建筑结构的美学外观，并可以达到各种装饰目的。材料设计将针对绿色和可观的生产量身定制。 这项创新将展示新型材料和产品的设计，以改善室内环境的质量，这可以导致公共生活的显着改善并降低医疗保健成本。 这种创新将扩大多功能建筑信封的视野。 它还将通过研究项目培训学生，这些项目在设计和测试创新材料，绿色制造和智能建筑包络等领域提高了年轻研究人员的跨学科能力。这项研究的目的是通过微型和光活动化学调节来优化创新的多功能光启发纤维复合型的创新性多功能光启发纤维复合。这项研究的假设是1）可以实施非金属掺杂氧化钛纳米材料的绿色制造程序，以将激活光谱从紫外线扩展到可见的和红外范围； 2）可以通过复合纳米纤维结构来实现高效率光催化空气清洁。 项目任务包括：1）开发经济有效的合成技术，用于在可见的和/或近缘范围内具有扩展激活光谱的非金属掺杂氧化钛纳米材料的制造技术； 2）表征非金属掺杂氧化钛的光催化效率； 3）考虑多功能设计矩阵和应用方法，优化宽带光催化纳米纤维复合垫的设计； 4）量化并微调纳米纤维垫的光催化效率和耐用性。
