Description
酸化グラフェンをHCl溶液及びアセトンで洗浄して、酸化グラフェンの形成中に残存する金属不純物(例えば、マンガン)を除去する。洗浄した酸化グラフェンを40℃の電気オーブンで一晩乾燥する。乾燥した酸化グラフェン30mgを水30mlに分散させる。CoCl2・6H2Oを水に3mg/mlで分散させ、この溶液202μlを酸化グラフェン溶液に添加する。混合溶液を1時間超音波処理し、次いで2日間凍結乾燥する。このようにして製造された金属が吸着されたグラフェン酸化物フォームをアルミナるつぼに入れ、チューブ炉の中央に配置する。アンモニア(50sccm)とアルゴン(150sccm)ガスを連続的に供給しながらチューブ炉を5℃/minの昇温速度で500℃まで加熱し、500℃で1時間保持した後、アルゴンの連続流(150sccm)下で自然冷却する。これにより、暗褐色のCo1-NG(O)触媒が製造される。
