Electrospun TiC/C nano-Felt Surface-decorated with Pt nanoparticles as highly efficient and cost-effective counter electrode for dye-sensitized solar cells.
Nanoscale, 2013Co-Authors: Yong Zhao, Amit Thapa, Quan Feng, Min Xi, Qiquan Qiao, Hao FongAbstract:Electrospun nano-Felt consisting of overlaid TiC/C composite nanofibers was Surface-decorated with Pt nanoparticles (Pt NPs) for use as highly efficient and cost-effective counter electrode (CE) in dye-sensitized solar cells (DSSCs). In the nanofibers, the self-generated TiC crystallites (∼70 wt%) with sizes of ∼20 nm were randomly embedded in carbon (∼30 wt%). Upon Surface-decoration, most Pt NPs were distributed on TiC crystallites, leading to substantial enhancement in the electrocatalytic activity/efficiency of Pt due to the strong interaction between Pt and TiC as well as the resulting synergetic effect on electrocatalysis. Electrochemical measurements indicated that the TiC/C–Pt CE exhibited low charge transfer resistance (Rct), large capacitance (C), and fast reaction rate towards the reduction of I3− ions, and the prototype DSSC exhibited a performance comparable to that with conventional Pt CE in terms of short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF), and energy conversion efficiency (η).

electrospun carbon nano Felt Surface attached with pd nanoparticles for hydrogen sensing application
Materials Letters, 2012Co-Authors: Lifeng Zhang, Xiaoxu Wang, Yong Zhao, Hao FongAbstract:Abstract Carbon nanofibrous mat (nano-Felt) Surface-attached with Pd nanoparticles was prepared from electrospun polyacrylonitrile nano-Felt Surface-functionalized with amidoxime groups, and its application for hydrogen sensing was explored. The material consisted of relatively uniform and randomly overlaid carbon nanofibers with diameters of ~ 300 nm, while the attached Pd nanoparticles had sizes in the range from a few to tens of nanometers. The electrospun carbon nano-Felt was mechanically flexible/resilient, and the resistance of the material varied upon exposure to H2 at room temperature. The study suggested that electrospun carbon nano-Felts Surface-attached with metal nanoparticles could be a material of choice for the fabrication of gas- and/or bio-sensors, and the amidoxime-functionalization of electrospun polyacrylonitrile nano-Felt could be a general approach for the development of various carbon nano-Felts Surface-attached with different metal nanoparticles.
