Multifunctional air-purification system based on supported porous graphitic carbon nitride for visible-light-driven photocatalytic removal of volatile organic compounds, filtering out particulate matters and antibacterial activity
Project ID: 2019-2.1.12-TÉT_VN-2020-00009
Project description:
Currently this project addresses a complex solution to air pollution. Typical air pollutants include volatile organic compounds (VOCs), airborne dust, and airborne microorganisms. Each of these presences can be a serious health risk. High Efficiency Oxidation Processes (AOPs) offer effective methods for tackling purification problems. Photocatalysis is one of the important representative of AOPs, which is a promising technology for solving air pollution problems, especially indoors, as it also prevents formation of secondary pollution. For the practical application of heterogeneous photocatalysis, it is essential to fix the powdery photocatalysts on a suitable support, which can eliminate costly post-separation processes. In addition, the fixed photocatalyst’s porous structure facilitates the effective adsorption of airborne pollutants, including microorganisms. Thus, the oxidative reagents formed under the influence of light transform them into harmless compounds, which also provide a significant antibacterial effect. The main objective of this project is the development and production of a fixed porous photocatalyst with enhanced activity in the visible range of light for the photo-oxidation of volatile organic compounds, combined with efficient removal of airborne dust and microbes for air purification systems. Utilizing this photocatalyst, we will prepare a prototype of a multifunctional air purification device for indoor use. This goal will be achieved through close cooperation between research teams and developers from two higher education institutions, the Hanoi University of Technology and Science and the University of Pannonia, Veszprém, and a Hungarian company (Knot Ltd.). The Vietnamese scientists are experts in analytics and modelling, while the Hungarians are mainly experts in catalyst development and photocatalysis, and in instrument design and construction.
