刺球状Pt 纳米粒子的红外性能
IR investigation of Pt nanothorn assembles
Pt 纳米结构的聚集体，具有一些特殊的性质。本文研究了刺球状Pt纳米粒子的红外光谱性能。与本体Pt的单极向下谱峰不同，CO在沉积于玻碳电极表面的刺球状Pt纳米粒子上的红外谱峰为双极峰，这可能与刺球状Pt纳米粒子的特殊结构有关。运用原位时间分辨光谱得到刺球状Pt纳米粒子相对于本体Pt 电极的红外增强因子为17，显示刺球状Pt 纳米粒子具有较强的红外增强效应。
he assemble of Pt nanostructure usually have some distinguished properties. In this paper, we investigated the in situ IR spectra CO adsorbed on Pt nanothorn assembles, which are electrodeposited on glassy carbon substrate. The shape of IR spectra of CO adsorbed on Pt nanothorn assembles is bipolar, different from that on bulk Pt electrode (downward peak). Pt nanothorn assembles show significantly enhanced IR absorption, yielding an IR enhancement factor of 17.
