Analysis of Catalysts and Electro-catalyst Systems The significance of the porous nature of catalysts with respect to their performance, functionality and efficiency is well known. This can also be extended to electrocatalysts and electrode systems, zeolites and Metal Organic Frameworks. Analyses can be applied to finished systems or raw materials in a range of physical forms. Alternatively, the effects of catalyst use can be investigated through the analysis of a range of samples which have experienced varying degrees of use or regeneration. Key Techniques· Micropore Analysis - pore size, area and volume distribution Gas Adsorption - pore size, area  and volume distribution in the mesopore range Mercury Porosimetry - for pore size, pore volume & pore area distribution Mercury Porosimetry - for cavity to throat size evaluation Permeability and Tortuosity measurement via Mercury Porosimetry & Pycnometry Chemisorption by a range of gases for analysis of catalysts Density measurement - absolute density, bulk density & skeletal density Total Pore Volume measurement The personnel at MCA Services have extensive experience in the field of catalysis and the expertise to assist with interpretation of results to gain maximum insight into analysed materials. Benefits are extended through application of state-of-the-art software in order to obtain highly specialised reports and graphical representations. Our ongoing in-house research into the application of our analytical techniques is published in peer reviewed journals and via our blog pages. MCA Services offers a complete suite of techniques for the characterisation of material porosity. Gas adsorption, including dedicated micropore analysis, and mercury porosimetry provide the capability of analysing the entire range of pore sizes; micropores, through mesopores, to macropores. Supporting techniques include helium pycnometry and particle size analysis. Combination of helium and mercury displacement density values is routinely applied to the calculation of Total Pore Volume and compliments mercury porosimetry procedures. Whilst nitrogen is commonly applied to gas adsorption analyses, highly specialised options exists for gas adsorption through the provision of a wide range of alternative adsorptives. Carbon dioxide may be applied to micropore analysis and argon can be applied to both micropore analysis and the acquisition of full adsorption / desorption isotherms. Hydrogen, oxygen and water adsorption are also available. The application of mercury intrusion porosimetry is particularly suited to the analysis of catalyst samples. Combination with BET surface area and helium displacement density also allows for the assessment of permeability and tortuosity. Chemisorption, commonly by hydrogen or carbon monoxide, is also provided and routinely applied to the analysis of catalysts. Alternative gases are available on request and the analytical options allow for considerable scope to dictate precise analytical conditions.
