Hydroxyapatite-Supported Palladium Nanoclusters: A Highly Active Heterogeneous Catalyst for Selective Oxidation of Alcohols by Use of Molecular Oxygen
TL;DR: The present Pd catalyst does not require additives to complete the catalytic cycle, and the diameters of the generated Pd nanoclusters can be controlled upon acting on the alcohol substrates used.
Journal ArticleDOI
Controlled synthesis of hydroxyapatite-supported palladium complexes as highly efficient heterogeneous catalysts.
TL;DR: The PdHAP are one of the most active heterogeneous catalysts for both alcohol oxidation under an atmospheric O(2)() pressure and the Heck reaction reported to date and are recyclable in the above organic reactions.
Journal ArticleDOI
Vapor-phase reaction of polyols over copper catalysts
Satoshi Sato,Masaki Akiyama,Ryoji Takahashi,Ryoji Takahashi,Takayoshi Hara,Kanichiro Inui,Masahiro Yokota +6 more
TL;DR: In this paper, the vapor phase reaction of triols and diols was performed over copper metal catalysts, and a reaction mechanism for the dehydration of glycerol to form hydroxyacetone was proposed.
Journal ArticleDOI
Magnetically recoverable heterogeneous catalyst: Palladium nanocluster supported on hydroxyapatite-encapsulated γ-Fe2O3 nanocrystallites for highly efficient dehalogenation with molecular hydrogen
Takayoshi Hara,Tomohiro Kaneta,Kohsuke Mori,Takato Mitsudome,Tomoo Mizugaki,Kohki Ebitani,Kiyotomi Kaneda +6 more
TL;DR: In this article, the dechlorination of various organochlorides using atmospheric molecular hydrogen (H2) can be efficiently catalysed by magnetically separable Pd nanoclusters supported on the surface of hydroxyapatite-encapsulated γ-Fe2O3 (PdHAP-γ-Fe 2O3).
Journal ArticleDOI
Hydroxyapatite-bound cationic ruthenium complexes as novel heterogeneous lewis acid catalysts for Diels-Alder and aldol reactions.
TL;DR: Treatment of a hydroxyapatite-bound Ru complex with an aqueous solution of AgX afforded a new type of cationic Ru phosphate complex, having potentially vacant coordination sites and promoting Diels-Alder and Aldol reactions with high efficiencies.
