Cross-linked polyphosphazene microspheres with amino-groups have been successfully prepared by precipitation polymerization of hexachlorocylotriphosphazene and 4,4′-diaminodiphenyl ether. Then Au nanoparticles (Au NPs) were synthesized by in situ growth on the surface of amino-terminated polyphosphazene (PZS-NH 2 ) microspheres, which serve as a reducer and a stabilizer. The PZS-NH 2 ...
Pd is a well-known catalyst in a number of processes such as hydrogenation and hydrogenolysis. Here, measured magnetic properties of nanoparticles (NPs) of Pd with sizes D=12nm and 7.7nm are compared with those of bulk Pd. These investigations show that the broad maximum in the magnetic susceptibility χ=M/H vs. T data near 100K observed in bulk Pd is also observed in the NPs. In addition, the magnitude...
