WebHighly oriented pyrolytic graphite ( HOPG) is a highly pure and ordered form of synthetic graphite. It is characterised by a low mosaic spread angle, meaning that the individual graphite crystallites are well aligned with each other. The best HOPG samples have mosaic spreads of less than 1 degree. Web(HOPG) is used as a working-electrode for electrochemistry-based applications (e.g. batteries and hydrogen storage mate-rials) and graphene production.13–16 When HOPG …
