researchMy current research interest is focused on the synthesis of advanced materials belonging to a class of metal-organic frameworks (MOFs). A metal-organic framework is a coordination polymer with an open framework containing potential voids. Metal-organic frameworks contain metal centers or their clusters that are linked into extended structures by bridging organic ligands. Applications of MOFs are largely a consequence of their porosity and include areas such as: hydrogen and other gases storage, separations, CO2 capture, molecular recognition, catalysis, charge transport and adsorption/release of drugs.
At present a new research project*, financially supported by the National Science Centre in Poland, is being launched to study MOFs with expected proton-conducting properties. Metal-organic frameworks (MOFs) have recently emerged as possible candidates for proton-conducting (PC) application, which is strongly related to fuel cells technology. In this context proton-conducting materials play the role of solid-state electrolyte membranes (PEMs) that efficiently transport protons between electrodes. Several PCMOFs have now been reported to conduct at 10-3 S/cm or higher; with few examples exhibiting values even greater than 10-2 S/cm. However, high proton conductivity, albeit important, is not the only requirement for a better electrolyte. As highlighted in the recent reviews, low cost and ease in high volume manufacturing are crucial factors in terms of applications and large-scale use in many technologies. The majority of MOF preparations, including PCMOFs, have been typically solvent-based under solvothermal or non-solvothermal conditions. In this project it is planned to make a considerable effort towards solventless synthesis of these materials. The current project* is a follow-up of the previous one# on MOFs based on hydrazone linkers.
Numerous synthetic and analytical techniques (available either in Coordination Chemistry Group or in the cooperation with other research groups) are planned to be used in the project. Major techniques include:
- mechanochemical and solution-based syntheses, 'building-block' approach, 'metalloligand' concept
- elemental analysis, molecular spectroscopy (IR, Raman, ESR, NMR), X-ray diffraction (single-crystal, powder)
- TGA/QMS analysis, adsorption measurements, in situ Raman spectroscopy and powder X-ray diffraction; cyclic voltammetry; AC conductivity measurements
