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，室内环境中存在挥发性有机化合物会增加患癌症的风险。**虽然生物气溶胶可能是健康问题的原因，如过敏性鼻炎。因此，降低建筑环境中挥发性有机化合物和生物气溶胶的含量是非常必要的。在过去的几年里，人们提出了多种去除室内环境中生物气溶胶和挥发性有机化合物的机制。**近年来，纳米级光触媒空气净化技术得到了广泛应用。但是**这些技术有以下不足。首先，它们在没有光源的情况下降低了效率。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，如纳米银颗粒，如果不小心释放，可能会对健康造成危害。第三，这些技术很昂贵。**在本研究项目中，将制备并测试铜掺杂氧化钛去除室内环境中的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，它将成为去除室内环境中**生物气溶胶的额外力量。第三，它也在黑暗的环境中发挥作用。**第四，由于铜相对于其他掺杂金属是丰富的，该技术可以**以可承受的价格商业化。这个研究项目可以增加**合作公司的竞争年龄。空气净化技术在国内和国际市场的商业化将为加拿大的经济做出贡献。此外，这个项目也将是一个非常有用的职业导向的经验，为学生（HQP）参与这个项目。

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.
