Description
TECHNICAL DESCRIPTION
The invention relates to a method of preparing a composition containing nanoparticles comprises: contacting a mixture comprising a dendrite structured compound and a metal precursor compound in a fluid so that the mixture will not be soluble in the fluid; and chemically transforming metal precursor compound in to the nanoparticle composition.
BENEFITS
The process is safe as the process makes use of nontoxic and non-inflammable carbon dioxide gas medium, is cost effective as the process makes the use of abundant sources, and is eco-friendly as the process obtains recyclable residue. The composition has excellent abrasion resistivity, optical selectivity and with stability against chemical attacks and environmental aggressions and good catalytic properties.
INDUSTRIAL APPLICATIONS
The nanoparticle composition is useful as catalyst in organic synthesis, surface coating and as contrast agent for the medical imaging science.
