This Small Business Innovation Research Phase I project will develop a material which when added to commercial paint and coatings can improve indoor air quality by actively removing and degrading Volatile Organic Compounds (VOCs). Indoor air quality is generally five times worse than outdoor air quality and VOCs are prevalent in indoor environments, being emitted from typical household items like electronics, cleaners, and flooring. People spend 90% of their lives in indoor environments, making poor indoor air quality a more acute health risk. VOCs are known to cause and worsen allergic diseases such as asthma and eczema, which combined, costs the United States approximately $56 billion in medical spending and lost work productivity every year. Alleviating the discomfort and financial burdens posed by allergic diseases can improve the standard of living of over 60 million affected Americans in the United States. Low- and zero-VOC paints ($9 billion market) are the fastest growing segment of architectural paints ($62 billion market). This technology has the potential to dramatically improve indoor air quality and make everyday living better for children, the elderly, and adults suffering from allergic diseases.The intellectual merit of this project will further the understanding of using diatoms in conjunction with a photocatalyst to harvest light as an energy source for the removal of pollutants from environments. Diatoms have been shown to increase the collection of ultraviolet, blue and red wavelengths of light. As a substrate for photocatalysts which utilize these wavelengths, diatoms may provide a superior light collection capability, increasing the effectiveness of photocatalysts. The proposed aim is to show an increase in the photocatalytic rate of VOC degradation which could help to make metal oxide photocatalysis a more viable option for air treatment. The proposed research makes the following contributions: 1) advancement of efficient visible light photocatalysis with a diatom-based additive; 2) understanding integration of photocatalytic paint additives into base paint and coatings mixtures, optimized for minimal paint substrate degradation and maximal photocatalytic degradation of indoor air-pollutants; and 3) long-term improvement of indoor air quality. Overall it is expected that this Phase I will show diatoms, as substrates, can increase the rate of photocatalysts up to two times under typical irradiation sources. This project targets cleaner indoor environments through pollutant removal activity without increased energy usage.

这个小型企业创新研究阶段I项目将开发一种材料，当将其添加到商业油漆和涂料中时，可以通过积极去除和降解挥发性有机化合物（VOC）来改善室内空气质量。室内空气质量通常比室外空气质量差五倍，而在室内环境中，VOC是由电子，清洁剂和地板等典型的家用物品发出的。人们在室内环境中度过了90％的终生，使室内空气质量较差变得更加严重。众所周知，VOC会导致并恶化过敏性疾病，例如哮喘和湿疹，这些疾病总共使美国损失了约560亿美元的医疗支出，并且每年失去了工作效率。减轻过敏性疾病带来的不适和经济负担可以改善美国超过6000万受影响的美国人的生活水平。低VOC涂料（90亿美元）是建筑涂料中增长最快的部分（620亿美元）。这项技术有可能显着提高室内空气质量，并使日常生活更好地适合儿童，老年人和患有过敏性疾病的成年人。该项目的智力优点将进一步了解将硅藻与光催化剂结合使用，以收获光源，以收获光源作为将污染物从环境中移除的能量来源。已显示硅藻会增加光的紫外线，蓝色和红色波长的收集。作为利用这些波长的光催化剂的底物，硅藻可以提供出色的光收集能力，从而提高光催化剂的有效性。拟议的目的是显示出VOC降解的光催化速率的提高，这可能有助于使金属氧化物光催化成为空气处理的更可行的选择。拟议的研究做出了以下贡献：1）具有基于硅藻的添加剂的有效可见光光催化的进步； 2）了解将光催化涂料添加剂整合到基础油漆和涂料混合物中，以最小的油漆底物降解和最大的室内空气污染物的最大光催化降解； 3）长期改善室内空气质量。总体而言，预计该阶段将显示硅藻，因为底物可以在典型的辐射源下将光催化剂的速率提高两次。该项目通过污染物的清除活动靶向更清洁的室内环境，而无需增加能量。
