Mesostructured silica-based materials. Synthesis, characterisation and adsoption properties
Mesoporous silica, aluminosilicates, as well as ceria-silica and titania-silica nanocomposites exhibit high surface area and pore volume, ordered pore array, non-toxic behavior, the possibility of the pore surface functionalization with different organic groups, tunable pore size and acidity. They can be used as efficient sorbents for different organic or inorganic pollutants, the adsorption properties depending on the pore size, type of interaction between mesoporous compound and pollutant.
We have synthesized different mesoporous materials, MCM41, SBA15, as well as CeO2-SiO2, TiO2-SiO2 composites by sol-gel technique associated with hydrothermal method. The textural features of the mesostructured silica-based materials were tuned by using different structure directing agents (cetyltrimethylammonium bromide, tetradecyltrimethylammonium bromide, and Pluronic P123) and various cerium or titanium precursors. The carriers were characterized by low and wide angle X-ray diffraction, nitrogen adsorption/desorption isotherms, FTIR spectroscopy, scanning and transmission electron microscopy.
We have studied the adsoption properties of synthesized mesostructured materials on tetracycline's class of antibiotics. The maximum permissible concentration of these antibiotics in industrial and pharmacy wastewaters is very low (1mg/L) and we focused our efforts to study the antibiotic-mesoporous material interactions and to establish the properties of an efficient sorbent for pollution control of industrial waters.

Welcome
to the European Conference on Materials and Technologies for Sustainable Growth website.
ECo MaTech will be held in Bled (Slovenia) from 19th to 21st of September 2013.
Eco MaTech is the third edition of a conference that started in 2009. The aim of ECo MaTech is to gather representatives of academic and R&D institutions, industry, governmental agencies and civil society to:
- present their work, ideas and products,
- increase fruitful exhanges between all the actors involved in sustainable growth technologies,
- increase the networking with sustainable growth professionals,
- establish a general discussion platform on sustainable growth.
