Abstract

Contrary to previous assumptions zinc–graphite obtained by the reduction of zinc chloride with lamellar potassium–graphite (C₈K) consists of finely dispersed zinc unevenly distributed on graphite as a support. While combined energy-dispersive X-ray analysis spectroscopy, electron energy loss spectroscopy, electron and X-ray diffraction showed no sign of intercalation of zinc in the graphite lattice it clearly proved the deleterious effect of water on the highly active metals. In fact, water-treated zinc–graphite is completely converted to zinc oxide on graphite.
