Description
しかしながら、最近の技術の進展に伴い、触媒の使用環境は更に過酷となったため、触媒担体に対しても、耐久性を含む性能の更なる改善が必要となっている。
なお、細孔径及び積算細孔容積の算出に当たっては、いくつかの解析手法があるが、吸着過程の吸着等温線をDollimore−Heal法(DH法)で解析して算出することができる。
炭素材料の構造は、日立ハイテクノロジーズ製電界放出形走査電子顕微鏡(SEM)SU−9000型を用いて形状を観察し、カーボンナノデンドライト構造の有無を確認した。
25℃における水蒸気相対圧10%における水蒸気吸着量(mL/g)(V10)を窒素吸着BET表面積(m2/g)(S)で割り、単位面積当たりの水蒸気吸着量(mL/m2)(V10/S;Q値)を算出した。
最初に、硝酸銀を1.1モル %の濃度で含むアンモニア水溶液(1.9%)150mLをフラスコに用意し、アルゴンや乾燥窒素などの不活性ガスで残留酸素を除去した。この溶液を攪拌し、超音波振動子を液体に浸して振動を与えながら、アセチレンガスをこの溶液に対し25mL/minの流速で約4分間吹き入れた。
第2熱処理の温度を1800℃とした以外は、実施例1と同様に処理して、炭素材料を得た。
第2熱処理の温度を2000℃、処理時間を0.5時間とした以外は、実施例1と同様に処理して、炭素材料を得た。
第2熱処理の加熱時間を2時間とした以外は、実施例3と同様に処理して、炭素材料を得た。
第2熱処理の加熱時間を4時間とした以外は、実施例3と同様に処理して、炭素材料を得た。実施例5で得られた炭素材料のXRD回折例を図3に示す。
第2熱処理の温度を2200℃とした以外は、実施例1と同様に処理して、炭素材料を得た。
第2熱処理の温度を200℃とした以外は、実施例1と同様に処理して、炭素材料を得た。比較例1で得られた炭素材料のXRD回折例を図4に示す。
第2熱処理の温度を800℃とした以外は、実施例1と同様に処理して、炭素材料を得た。
第2熱処理の温度を1200℃とした以外は、実施例1と同様に処理して、炭素材料を得た。
