text: The synthesis of novel robust and stable iridium-based immobilized catalysts
on silica-polymer hybrid materials (Si-PB-Ir) is described. These catalysts are
characterized by a combination of 1D P-31 CP-MAS and 2D P-31-H-1 HETCOR and J-resolved
multinuclear solid state NMR experiments. Different binding situations such as
singly and multiply coordinated phosphines are identified. Density functional
theory (DFT) calculations are performed to corroborate the interpretation of the
experimental NMR data, in order to propose a structural model of the heterogenized
catalysts. Finally, the catalytic activity of the Si-PB-Ir catalysts is investigated
for the hydrogenation of styrene employing para-enriched hydrogen gas.

text: The thermolysis of electrodeposited metal–organic framework (MOF) films represents
a novel approach to build supercapacitor electrodes of already electrically contacted
MOF-derived high-performance metal oxide/carbon materials which are also highly
interesting for other applications. MOFs are widely utilised as precursors to
synthesise functional materials by thermal decomposition (pyrolysis, carbonisation).
Using electrochemically coated MOF precursor films instead of powder greatly simplifies
the processing of such materials and potentially enhances the resulting active
materials' performance. In the case of electrochemical energy storage electrodes,
the coated substrate later functions as current collector which is well-attached
to the active material without the need for any additives. This close connection
decreases electron transfer resistances and saves multiple steps of powder formulation
and coating. Films of a metal–organic framework based on 1,3,5-benzene-tricarboxylate
(BTC) and cobalt(II) cations were electrochemically coated on cobalt foils which
act as the Co2+ cation source. Manganese films were electrodeposited and subsequently
partly redissolved in a linker-containing electrolyte to achieve Mn/Mn–BTC bilayered
films on stainless steel. This procedure extends the method for any kind of current
collector material. The films were thermolysed to gain nanostructured metal oxide
spinel (Me3O4)/carbon hybrid electrodes. Investigations of the electrochemical
properties in regard to supercapacitor applications show that Co3O4/C films exhibit
pseudocapacitance and that Mn3O4/C films are suitable for redox electrodes with
high-rate capability operating in a wide potential range in aqueous electrolytes.
Co–BTC powder was also thermally treated yielding cobalt particles embedded in
a graphitic carbon matrix. The pseudocapacitive properties of conventionally coated
films of this powder material are limited.
