Abstract
【解決手段】竹を、四塩化チタンの存在下にて加熱して炭化することにより得られたものであり、炭素体と、上記炭素体に含有されたTiC系化合物とを備えている。TiC系化合物の含有は、得られたTi−C系材料のX線回折法による、2θ=36.2°、42.3°、および61.6°の回折線ピークがTiCにおける(111)、(200)、および(220)に対応することにより確認された。
【選択図】図1
Description
A.Fujishima and K.Honda, Nature 238, p37(1972) 「光触媒」窪川、本田、斉藤 共編、朝倉書店(1998) S.Sakthivel and H.Kisch, Angew.Chem.Int.Ed., 42, p4908(2003)
.0Vの範囲内とした。光照射用光源として、500Wハロゲンランプ(ピーク波長:1
200nm)を用いた。上記ハロゲンランプは、紫外線領域の波長の光を殆ど含まず、可視光領域から赤外領域の光が主に発光するものである。
合体であり、その複合体の表面には、ESCA(Ti2p)スペクトルの測定結果に基づきTi−O結合が存在することが判明した。ESCAとは、化学分析用電子分光のことであり、Electron Spectroscopy for Chemical Analysisの略称である。
、および61.6°の各回折線ピークは、表1に示すように、それぞれTiCにおける(111)、(200)、および(220)に対応し、その他のブロードな回折線は非晶質カーボンに起因するものである。参考のため、竹を熱処理して得られた材料は非晶質カーボンであることがX線回折の結果よりわかった(図2)。
であり、JCPDS(Joint Committee on Powder Diffraction Standards)カードに掲載されているものである。
密度で−20mA/cm2(図5:竹炭)と、−1mA/cm2(図6:酸化チタン)と比較的小さかった。これに対し、Ti−C材料(図4)の場合については−100mA/cm2〜−150mA/cm2と5倍以上大きかった。飽和カロメル参照電極基準で−0.3V付近の電流密度は、水素(陰極で生成:H++e-→(1/2)H2)の発生量に
相当する。
