Texte intégralIndoor air pollution is an important cause of diverse health problems for occupants including respiratory diseases, allergic symptoms, cancers, and cardiovascular problems. People spend 80-90% of their time indoors emphasizing the importance of understanding the main causes of indoor air pollution and finding suitable solutions to improve indoor air quality. The World Health Organization (WHO) reported in 2009 that biological pollution is one of the main causes of the degradation of indoor quality. In humid indoor environments, fungi can grow and develop on almost all building materials. Upon their development on surfaces, they produce particles such as spores, toxins or volatile organic compounds, and other metabolites that can be aerosolized. The release of particles from surfaces as well as their characteristics is dependent on different factors including the type and age of microorganisms on the surface, material properties, and environmental conditions (temperature, humidity, air velocity). Based on their sizes and their duration of availability in the indoor air, they can be inhaled by occupants, leading to serious health risks as they may penetrate different depths in the respiratory system. To respond to these issues, this work aimed to investigate the relations that may exist between microorganisms, especially fungi, present on surfaces and airborne particles contaminating the indoor air (In situ and in the lab). It would provide a clearer vision of fungal contamination in the indoor environment and would be helpful during investigating methods for controlling the growth of fungi indoors. In addition, investigations on the performances of selected photocatalysts and glycerol esters as antimicrobial products for reducing microbial contamination on surfaces in the laboratory were achieved. Initially, an In situ sampling campaign was held in a visibly contaminated house in Southern France. Surface sampling from contaminated materials and indoor airborne sampling were carried out. Then, DNA analysis for samples was carried out by Toulouse Biotechnology Institute (TBI). This part aimed to check the relationship, if any, between fungal contamination on surfaces and airborne contamination. Then, experiments on the antifungal and antibacterial activities of photocatalytic products and the antifungal activity of glycerol esters were carried out under different experimental conditions. This part aimed to test their efficiency as antibacterial/antifungal products that may be applied as additives in paints or coatings. The tests carried out in this part were preliminary tests in aqueous solutions and the impact of different conditions on the efficiency of each product was evaluated. The efficiency of three photocatalysts (TiO2, ZnO, Au-decorated ZnO) as antimicrobial products under light intensities close to real-life indoor conditions. The efficiencies of Undecylenic Acid (UA) and of three glycerol esters, formed upon esterification of Glycerols with UA, as antifungal products were evaluated. The last part of this study aimed to investigate the relationship between surface contamination and airborne contamination under controlled conditions (mainly airflow and relative humidity). A new experimental device was settled, design and validation of an experiment protocol that permit to determine the quantitative correlation between surface contamination and airborne contamination were carried out. The impact of different experimental parameters on the aerosolization of particles from contaminated surfaces into air was evaluated. The validation of this experimental protocol was important and brought attention to different tests that will be investigated in the near future

This thesis focus on exploring essentially robust and practically efficient photocatalyst platform in order to make significant breakthrough to the ever-challenging fields of environmental sustainability and renewable energy. We developed the intelligent photocatalyst and demonstrated the correlations of their interfacial charge dynamics and photocatalytic activity including typical semiconductor/metal heterostructure photocatalyst system, ZnO/Metal (Ag, Au, Pd), especially for the quantitative analysis on the SPR-induced interfacial charge dynamics of ZnO-Au system. The correlations among plasmonic metal content, surface plasmon resonance-mediated charge transfer and electromagnetic response, and the resultant photoactivity enhancement toward photoelectrochemical (PEC) water splitting provide a solid foundation for creating effective and applicable plasmonic PEC cells. We also introduced Ta, Nb, Zr into TiO2 nanotube system to modify its electronic structures and established a fully depleted quaternary Ti−Nb−Ta−Zr−O (TNTZO) mixed-oxide nanotube arrays to serve as a versatile structural backbone for construction of a sophisticated photoelectrode paradigm. Besides, by coupling the pronounced charge separation and distinctive peroxidase mimic features, an all-day-active photocatalyst, Au@Cu7S4 nanocrystal-decorated TiO2 nanowires, were also successfully synthesized.

Highly ordered TiO2 nanotube arrays are fabricated via electrochemical anodization of high purity titanium metal sheet in fluorine containing electrolytes. The microstructures were characterized by GIXRD, XPS, SEM, synchrotron radiation beam line 17B and beam line 24 analyses. Using a solar simulator measurement, the photocurrent density and photoelectric conversion of the TiO2 nanotubes was evaluated and discussed. The photoconversion efficiency of silver loading TiO2 nanotubes following hydrogenation treatment at 300°C for 3hs was found to be improved comparing with the highly ordered TiO2 nanotubes arrays. With silver loading, the TiO2 nanotubes can achieve 0.64% in efficiency with 0.52 mA/cm2 in photocurrent density for hydrogen production; after the hydrogenation treatment, the efficiency and photocurrent density increase to 0.87% and 0.79 mA/cm2, respectively. The efficiency of the silver-loaded TiO2 nanotubes and hydrogenation treatment also will be discussed.
