Ligand‐Stabilized Bimetallic Colloids Identified by HRTEM and EDX

Schmid, Günter, Lehnert, Andreas, Malm, Jan‐Olle, Bovin, Jan‐Olov·1991·Angewandte Chemie International Edition in English

Abstract

Gold colloids are covered by platinum and palladium shells when an aqueous solution of the colloids is added to a solution of H2PtC16 or H2PdCl4 and H3NOHCl, stabilizing the particles thus formed with p-H2NC6H4SO3Na. A heterogenous agglomerate is formed for the Au/Pt system, a homogeneous system with well-ordered shells of palladium atoms for Au/Pd, as is shown by the electron microscope image (illustration on the right) and the optical diffractogram (insert). Such studies are relevant to the clarification of the mechanism for alloy formation and for heterogeneous catalysis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
