Abstract
Ultrafine cobalt–nickel bimetallic phosphides were prepared by mild hydrothermal method and characterized by techniques, such as XRD, EDS, and TEM. The results showed that the as-prepared products were well crystallized and particle sizes ranged from 10 to 20 nm. With the increasing amount of Ni2+ in the suspensions, the crystallinity of obtained products was improved gradually and the crystallite sizes increased accordingly.
Highlights
Transition metal phosphide compounds have great application prospects in the catalytic agent (Brock and Senevirathne 2008; Rodriguez et al 2003) due to their excellent antisulfurpoisoning property and superior catalytic activity
Ultrafine cobalt–nickel bimetallic phosphides were prepared by mild hydrothermal method and characterized by techniques, such as X-ray powder diffraction (XRD), EDS, and transmission electron microscopy (TEM)
When the ratio of Ni/Co/P was 1:25:125 (Group 6), the main peaks were hardly observed which should be attributed to small crystallite sizes
