A Hybrid CuxO/TiO2 composite as a risk reduction material against infection disease and sick house syndrome in indoor environment
Indoor air quality has been becoming a more and more important determinant of population health and wellbeing, due to the increased amount of personal time spent in indoor spaces such as at home, work or other public places.1,2Indoor air pollutions are mainly due to volatile organic compounds (VOCs) issued by various sources, which is the major cause of sick house syndrome. Furthermore, infectious bacteria and viruses with multiple drug resistance appear in our daily environment, and they become big problems for human health.3 TiO2 is recognized as the most promising candidate for environmental remediation, owing to its low cost, non-toxicity, high stability and high efficiencies. However, for indoor application, visible light and/or dark sensitivity has to be appended. Herein, we initiated the preparation of multifunctional CurO/TiO2 nanocomposites with well controllable Cu+/Cu2+ ratio. The CuxO/TiO2 nanocomposites exhibited efficient visible light decomposition of VOCs and anti-bacteria and anti-virus properties in the dark condition.
