Description
小麦粉(8000g)を黒鉛坩堝に入れ、レトルト炉(CM Furnaces、Model 1212FL)内で加熱する。炉の温度を、室温から800℃まで150℃/時の加熱速度で上昇させ、2時間に亘り800℃に維持し、次いで、70℃以下に自然に冷ます。上述した加熱/冷却サイクル中、炉をN2でパージする。
ココナッツの殻に由来する市販の水蒸気活性化された炭素を使用して、第2の活性炭材料を調製した。
市販のカーボンブラック(「Black Pearls」、マサチューセッツ州ボストン所在のCabot Corporation)の全酸素含有量が、このカーボンブラックをフォーミングガス環境(N2中1%のH2)内において675℃で加熱する工程を含む精製工程によって、1.3質量%から約0.4質量%に減少した。
最終的な熱処理を、1%のH2/N2混合物内で675℃の代わりに900℃で行うことを除いて、サンプルAC−1aに使用したのと同じ過程を使用して、サンプルAC−3を作製する。理論により束縛するものではないが、熱処理温度は、表面官能化において重要な役割を果たすと考えられるので、AC−3に関する全酸素含有量と酸素含有官能基、表面積、細孔容積、および細孔径分布は、AC−1bのものと似ていると予測される。AC−3に関する不純物濃度が、表4bに示されている。
サンプルAC−4aはサンプルAC−2aと同じである。サンプルAC−4bは、洗浄を行わずに、1%のH2/N2内において900℃でサンプルAC−4aの一部を熱処理することによって得られる。AC−4aおよびAC−4bに関する全酸素含有量と酸素含有官能基、表面積、細孔容積、および細孔径分布は、それぞれ、AC−1aおよびAC−1bのものと似ていると予測される。AC−4aおよびAC−4bの不純物濃度が、表4bに示されている。
