Analytical electron microscopy discloses actual structure of zinc–graphite

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.
