SYNTHESIS OF BIMETALLIC STRUCTURES FOR USE AS CATALYSTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18227154 titled 'SYNTHESIS OF BIMETALLIC STRUCTURES FOR USE AS CATALYSTS

Simplified Explanation

The patent application describes a process for creating bimetallic nanoframes using platinum (Pt) and a Group 8-11 metal (M).

  • The process involves reacting a first precursor containing Pt and a second precursor containing M to form a first bimetallic structure.
  • A third precursor containing Pt is then reacted with the first bimetallic structure to form a second bimetallic structure with a higher molar ratio of Pt to M.
  • The second bimetallic structure is then treated with an acid to form the bimetallic nanoframe, which has an even higher molar ratio of Pt to M.
  • The resulting bimetallic nanoframe has the formula (Pt)(M), where a represents the amount of Pt and b represents the amount of M.


Original Abstract Submitted

Aspects described herein generally relate to bimetallic structures, syntheses thereof, and uses thereof. In an embodiment, a process for forming a bimetallic nanoframe is provided. The process includes forming a first bimetallic structure by reacting a first precursor comprising platinum (Pt) and a second precursor comprising a Group 8-11 metal (M), wherein Mis free of Pt; reacting a third precursor comprising Pt with the first bimetallic structure to form a second bimetallic structure, the second bimetallic structure having a higher molar ratio of Pt to Group 8-11 metal than the first bimetallic structure; and introducing the second bimetallic structure with an acid to form the bimetallic nanoframe, the bimetallic nanoframe having a higher molar ratio of Pt to Group 8-11 metal than that of the second bimetallic structure, the bimetallic nanoframe having the formula: (Pt)(M), wherein: a is the amount of Pt; b is the amount of M.
