Co2P nanostructures by thermal decomposition: phase formation and magnetic properties
CrystEngComm, 2012, 14, 1197–1200,-0001,():
We have synthesized firework-like Co2P nanostructures using a simple and reliable thermal decomposition route with the precursors, triphenyl phosphine and cobalt acetylacetonate, in oleylamine. The optimized reaction temperature is within a narrow window around 280 _C. The nanostructures have a firework-like morphology with nanoneedles growing out of a center core. The nanoneedles are single crystals with clean surfaces, about 200 nm in length, and a tapering tip less than 10 nm in diameter. These nanostructures exhibit Curie–Weiss PM behavior with the effective moment determined as 2.46 mB per FU. Based on the synthesis designs with detailed characterizations on the intermediates at different stages of the phase formation, the growth mechanism of the firework-like Co2P nanostructures is proposed. It is feasible to apply this method of synthesis for some of the other transition-metal phosphide nanostructures.
