Facile One-Pot Synthesis of PbSe and NiSe2 Hollow Spheres:Kirkendall-Effect-I…

A facile one-pot polyol process for the synthesis of PbSe and NiSe2 hollow spheres, using R-Se solid spheres as starting core materials was successfully developed. The careful characterization of the timedependent products demonstrates that the Kirkendall effect could be the involved growth mechanism for the evolution process from Se solid spheres to PbSe and NiSe2 hollow spheres, which is sc…
