Intermetallic compounds (IMCs)composed of transition metals and post-transition metals function as superior heterogeneousc atalysts in comparison to their monometallic and bimetallic alloy counterparts. Rendering IMCs in their nanomaterial iterations further enhances their efficiency. Herein, we demonstrate the role of PdIn as well-dispersed intermetallic nanoparticles (IMNPs) for the semihydrogenation of phenylacetylene selectively to styrene at ambient conditions. Higher selectivity of PdIn wase xplained with the help DOS calculations. We have explored the role of af ew well-known silica-based supports such as SBA-15 and MCM-41, providing insight into how they affect catalysis. As an additional support we have explored previously reportedJ NC-1, am esoporousc arbon material obtained via at emplated strategyu sing SBA-15. PdIn supported on SBA-15 and JNC-1 displayed the best dispersion, while also exhibiting the most catalytic activity due to the unique nature of the porous structure.
Different Schiff base functionalized SBA-15 materials were synthesized through the condensation reactions between 3-aminopropyltriethoxysilane (APTES) and different aldehydes (Glutaraldehyde and Butyraldehyde) over a mesoporous silica, SBA-15 (APTES-GLU/SBA-15 and APTES-BUT/SBA-15). Both...
The
scientific community has found immense difficulty
to focus
on the generation of chiral intermetallics compared to the chiral
molecular structure, probably due to the technical difficulty in producing
them as no general controlled protocol is available. Herein, using
a conventional metal flux technique, we have discovered a new ternary
intermetallic Co3Ni3Ga8, substituting
Co at the Ni sublattice in a highly symmetric Ni3Ga4 (Ia3̅d). Co3Ni3Ga8 crystallizes in the I4132 space group, a Sohncke type, and can host the chiral
structure. To the best of our knowledge, this is the first report
of a ternary intermetallic crystallizing in this space group. The
chiral structure of Co3Ni3Ga8 is
comprehensively mapped by various techniques such as single-crystal
X-ray diffraction (XRD), synchrotron powder XRD, X-ray absorption
spectroscopy (XAS), scanning transmission electron microscopy (STEM)
and theoretically studied using density functional theory. The discovery
of this chiral compound can inspire the researchers to design hidden
ternary chiral intermetallics to study the exotic electrical and magnetic
properties.
