The Pt1/Co3O4-c catalysts exhibit great catalytic activities in hydrolytic dehydrogenation of ammonia borane (AB) with a specific rate of 6035 molH2 molPt-1 min-1 at room temperature. In-situ DRIFTS spectra and...
A single atom catalyst Fe1/NC, synthesized by ball milling with protein powder as the nitrogen source, exhibited superb performance for selective oxidation of ethylbenzene.
Palladium single-atom catalysts (SACs) have caught great
attention
owing to their maximal atom utilization and outstanding activity for
the Suzuki–Miyaura cross-coupling reaction. However, a facile
manufacturing method for kilogram-scale synthesis of noble metal SACs
with high productivity is still in demand. This study reports on the
synthesis of SACs by direct ball milling of commercial metal oxides
and nitrate precursors with a productivity of ∼100%. The as-prepared
Pd1/FeO

SACs show high catalytic
performance (the TOFs are 7844 h–1), high stability,
and general applicability for the Suzuki–Miyaura cross-coupling
reaction under mild conditions. More encouragingly, kilogram-scale

SACs can be synthesized
in one batch by this approach, endowing great potential for industrial
applications. Furthermore, the preparation of Pt, Ru, and Rh SACs
is also successfully carried out via the ball milling method, demonstrating
favorable applicability. Our findings illustrate exciting chances
presented by the highly efficient synthesis of SACs for the formation
of C–C bonds.
Atomically dispersed Pt species supported on Fe2O3 (Pt1/Fe2O3) are successfully constructed by a simple ball milling process. In the selective hydrogenation of cinnamaldehyde (CAL), Pt1/Fe2O3 achieves an excellent cinnamyl alcohol...
