采用聚合物配体辅助的方法制备了PtO修饰的多壁碳纳米管（MWCNTs），并首次将其用作染料敏化太阳能电池（DSC）的对电极。与基于Pt CE的DSC的能量转换效率（Eff）相比，具有PtO-MWCNTs CE的DSC显示出8.67%的总体Eff，给出了12.7%的提高。PtO-MWCNTs对I3−/I−氧化还原对的电催化活性优于Pt CE，表明PtO-MWCNTs是一种很有前途的DSCs电催化剂。
PtO decorated multi-walled carbon nanotubes (MWCNTs) were prepared by a polymer ligand assisted strategy and applied as the counter electrode (CE) in dye-sensitized solar cells (DSCs) for the first time. Compared with the energy conversion efficiency (Eff) of Pt CE based DSCs, the DSCs with PtO–MWCNTs CE showed an overall Eff of 8.67%, giving an improvement of 12.7%. Better electrocatalytic activity towards I3−/I− redox pairs than Pt CE indicated that the PtO–MWCNTs was a promising electrocatalyst for DSCs.
