The synthesis procedure was based on a literature report where a cyclohexane templating agent was used to tune the sample for a later incorporation of Pt particles. Solutions A and B were prepared, with A containing ZnO nanoparticles (1.221 g, 25 nm) dissolved in aqueous ammonia (25%, 300 ml), and B containing 2-ethylimidazole (2.88 g) dissolved in cyclohexane (22.5 ml) and methanol (225 ml). Solution B was well stirred, then solution A was dropped into solution B using a separatory funnel while continuing to stir solution B vigorously. The product was filtered off, washed with methanol and dried at 80 °C over two days. The product yield was 1.11 g.
