    The issue of organized nanoporous silica (PNS) emerged on the scene in the year 1992, and has since attracted great attention in global research. In Slovakia, it has been adapted and developed by the team members. As opposed to other forms of SiO2, the arranged nanoporous silica is characterized by evenly arranged, unimodal pores, the size of which can range from about 4 nm to 30 nm. This form of silica is prepared by a sol-gel method using self-arranging surfactants that form a structural motif in the synthesis. There exist different types of arranged nanoporous silica. The team members were involved in hexagonal symmetry silica (MCM-41, SBA-15) and cubic symmetry (SBA-12, SBA-16, MCM-48). The advantage of silica is that its surface can be chemically modified for different purposes. The team members have been involved in the designing silica- based syntheses of the arranged nanoporous materials, as well as in its use. The team members examined the use of PNS in the following areas:
