Nanoscale bimetallic CoxPt1-x particles dispersed in poly(vinylpyrrolidone): synthesis from organometallic precursors and characterization

Article Abstract:

It has been possible to demonstrate the synthesis of CoxPt1-x particles of nanometric size dispersed in an inert organic matrix through the simultaneous decomposition of the organometallic precursors Co(eta3-C8H13)(eta4-C8H12) and Pt2(dba)3 in solution in mild conditions.

Synthesis and magnetism of CoxRh(sub 1-x) and CoxRu(sub 1-x) nanoparticles

Article Abstract:

The synthesis of CoxRh(sub 1-x) and CoxRu(sub 1-x) alloys of nanometric size dispersed in a polymer matrix through the simultaneous decomposition of the organometallic precursors in solution in mild conditions is described. These structural studies enable to find some analogies between three CoM systems (M= Ru, Rh, Pt).

Synthesis of zeolitic mesoporous by dry gel conversion under controlled humidity

Article Abstract:

Vacuum-dried precursor gels could be converted to zeolite by water vapor even below saturation conditions. The effects of precursor preparation and surfactant flocculation conditions on mesoporosity and crystallinity of the final product, as well as the steam stability of the product, are investigated.
