This can be considered as a fairly unique synthesis strategy that does not require any additional external reductants. The synthesis is carried out in a nonpolar solvent and precise tuning of the cavity size has been achieved only by varying the ratio of the two reacting components. A detailed characterization has been performed via UV-vis spectroscopy, XPS, TEM, EDAX, and SEM. The mechanistic aspect is established from FTIR. SQUID-VSM confirmed the magnificent superparamagnetism of the nanocomposites.</p>1 aSardar, Debasmita1 aAhmed, Md, Azaharuddi1 aBandyopadhyay, Sudipta1 aGhosalya, Manoj, Kumar1 aBala, Tanushree  uhttps://library.ncl.res.in/content/organic-phase-transmetallation-approach-synthesis-hollow-ni-au-nanocomposites-tunable-cavity
