Development of methods for preparation of composites of porous matrixes with nanoparticles of desired composition


Obtaining electrochemically active electrode coatings on the basis of porous coordination polymers, incorporation of ferrimagnetic nanoparticles into porous matrices during the formation of such matrices or the creation of layers capable of immobilizing organic molecules on the surface of ferrimagnetic nanoparticles. Doping of mesoporous tin dioxide with In, Ce, Fe, V oxides to form Lewis and Brönsted acid sites of various strengths due to which the sensitivity (electrical conductivity) of the SnO2 films and spheres (~ 1 μm) to the analytes of different nature (ethanol, acetone, hexane , ammonia), which can be used to create sensitive sensor systems.

Development of methods for preparation of composites of nanoparticles and porous matrixes, such as:
- magnetic particles (such as Fe3O4) in porous sorbents for magnetic separation of sorbent from liquid media;
- metal oxide (such as Cr2O3) or metal (such as Pd, Pt) nanoparticles on porous supports for use as catalysts;
- quantum dot nanoparticles (such as CdS, CdSe) in porous matrixes for creation of luminescent porous materials; immobilization of organic dyes on porous silica materials for creation of dye-labeled silica particles.
- graphene grafting on mesoporous silica for use as catalysts.

Terms: from 1 to 6 months depending on the task.
