Copper doped titanium oxide nano tube fitted air purifier

挥发性有机化合物（VOC）和生物气溶胶是室内质量差的主要原因。据报道，室内环境中存在VOC会增加患癌症的风险。而生物气溶胶可能是引起过敏性鼻炎等健康问题的原因。因此，降低建筑环境中VOC和生物气溶胶的水平是非常必要的。在过去的几年中，已经提出了各种机制来去除室内环境中的生物气溶胶和挥发性有机化合物。基于纳米光催化剂的空气净化技术近年来已经流行。但这些技术存在以下不足。首先，它们在没有光源的情况下效率降低。其次，那些能够在黑暗环境下工作的技术是由纳米金属组成的，如银纳米颗粒，如果意外释放，可能会对健康造成危害。第三，技术成本高 **。在这项研究项目中，铜掺杂的氧化钛将被制备和测试，以消除室内环境中的VOC** 和生物气溶胶。结合这两种纳米材料具有以下优点。首先，它将有助于提高光催化剂的净化效率。**其次，由于铜具有抗生物气溶胶的性质，它将是从室内环境中去除生物气溶胶的额外力量。第三，它也可以在黑暗环境中工作。**第四，由于铜相对于其他掺杂金属来说是丰富的，因此该技术可以以负担得起的价格商业化。本研究计画可提升合作公司的竞争力。空气技术的商业化进入国内和国际市场将有助于加拿大的经济。此外，这个项目也将是一个非常有用的职业为导向的经验，为学生（HQP）参与该项目。

Volatile organic compounds (VOC) and bioaerosols are the main causes of poor indoor quality. It**has been reported that the presence of VOC in an indoor environment increase the risk of cancer.**While bioaerosols could be reasons for health concerns such as allergic rhinitis. Hence lowering**the levels of VOC and bioaerosols within the built environment is an important necessity. Over**the past several years various mechanisms have been proposed for bioaerosol and VOC removal**from indoor environments.**Nanoscale photocatalyst based air purifying technologies have been popular in recent years. But**these technologies have the following deficiencies. Firstly, they have decreased efficiency in the**absence of a light source. Secondly, those technologies which are capable of functioning under**dark environment are composed of nanometals such as silver nanoparticle, which could be health**hazards if released accidentally. Thirdly, the technologies are expensive.**In this research project, copper doped titanium oxide will be prepared and tested to remove VOC**and bioaerosols from the indoor environment. Combining these two nanomaterials have the**following advantages. Firstly, it will help increase the purification efficiency of the photocatalyst.**Secondly, since copper has anti-bioaerosol nature it will be an additional force for removing**bioaerosols from the indoor environment. Thirdly, it also functions in a dark environment.**Fourthly, because copper is abundant relative to the other doping metals, the technology can be**commercialized at an affordable price. This research project can increase the competitive age of**the partnering company. The commercialization of the air the technology into the domestic and**international market will contribute to Canada's economy. Furthermore, this project will also be a**very useful career-oriented experience for students (HQP) involved in the project.
