  text: Abstract Novel SBA-15-supported heterogeneous catalysts are synthesized and
    applied in the Mizoroki?Heck and the Suzuki?Miyaura cross-coupling reactions in
    green solvents like PEG or water. The structural properties of the products after
    each synthesis step are monitored by different analytics. The amount of amine/carboxyl
    groups and vanillin/histidine methyl ester and thermal stability are determined
    by TGA and elemental analysis, while ICP-OES delivered the amount of palladium
    of the catalysts. The morphology is investigated by SEM and XPS and confirms the
    presence of coordinated palladium in the zero-oxidation state. Gas adsorption
    analysis is conducted, which indicates the presence of palladium clusters in one
    of the two catalysts, which is underlined by BSE images combined with EDX. A detailed
    13C ssNMR and DNP-enhanced 15N ssNMR spectral analysis is presented, which provides
    ultimate proof of the successful syntheses of the catalysts. The coordination
    of the palladium onto the carrier material is shown by combining the NMR spectral
    results with the results of the other analytics. First catalytic tests show for
    the Mizoroki?Heck reaction yields up to nearly 100% and for the Suzuki-Miyaura
    up to 88% in the presence of PEG and water, respectively.

  text: The production of formaldehyde on industrial scale requires huge amounts of
    energy due to the involvement of reforming processes in combination with the demand
    in the megaton scale. Hence, a direct route for the transformation of (bio)methane
    to formaldehyde would decrease costs and puts less pressure on the environment.
    Herein, we report on the use of zinc modified silicas as possible support materials
    for vanadium catalysts and the resulting consequences for the performance in the
    selective oxidation of methane to formaldehyde. After optimization of the Zn content
    and reaction conditions, a remarkably high space-time yield of 12.4 kgCH2O·kgcat−1·h−1
    was achieved. As a result of the extensive characterization by means of UV–vis,
    Raman, XANES and NMR spectroscopy it was found that vanadium is in the vicinity
    of highly dispersed zinc atoms which promote the formation of active vanadium
    species as supposed by theoretical calculations. This work presents a further
    step of catalyst development towards direct industrial methane conversion which
    may help to overcome current limitations in the future.
