摘要： •Pd particles (∼5nm in diameter) are deposited on CNTs via a supercritical fluid.•Synthesized Pd nanoparticles are highly dispersed and tightly anchored on CNTs.•Decoration density of Pd particles on CNTs can be controlled.•The obtained composite electrode shows superior glucose sensing performance. With the aid of supercritical carbon dioxide (SCCO2), which has gas-like diffusivity, extremely low viscosity, and near-zero surface tension, the synthesized nano-sized Pd particles (approximately 5nm in diameter) are uniformly distributed on carbon nanotubes (CNTs). The decoration density of Pd nanoparticles on the CNTs can be simply controlled, without varying the particle size, by adjusting the Pd hexafluoroacetylacetonate precursor to CNT ratio. Since the Pd nanoparticles are highly dispersed and tightly anchored on the CNTs, the obtained composite shows enhanced electro-sensing performance toward glucose compared to that of the control sample prepared using a conventional deposition process (without SCCO2). 出版者： Kidlington: Elsevier B.V 出版日期： 2014-12-05 出處： Journal of Alloys and Compounds, 2014-12, Vol.615, p.S496-S500 版權： 2014 Elsevier B.V. 版權： 2015 INIST-CNRS 識別號： ISSN: 0925-8388 識別號： EISSN: 1873-4669 識別號： DOI: 10.1016/j.jallcom.2013.12.187
