采用原位水热生长法在泡沫镍基底上制备了β-Ni(OH)2纳米盘并通过煅烧获得NiO,均可以直接作为工作电极。利用XRD和SEM对样品进行了表征,并进行了电化学性能测试,结果表明我们所制备的Ni(OH)2电极在2 M KOH溶液中2.5 A/g的放电电流密度下,比容量达1495 F/g,通过煅烧得到的NiO,同样可以作为电极材料。
Titanium dioxide（TiO2） nanowires with different crystal structures were successfully synthesized, and their charge transfer properties were further investigated by surface photovoltage（SPV）, transient photovoltage（TPV） and surface photoeurrent（SPC） techniques. The results reveal that both the surface states and the charge transfer rate of different TiO2 nanowires are highly dependent on their crystal structures.
