Preparation and Characterization of Zirconia-Coated Nanodiamonds as a Pt Catalyst Support for Methanol Electro-Oxidation
Zirconia-coated nanodiamond (ZrO₂/ND) electrode material was successfully prepared by one-step isothermal hydrolyzing from ND-dispersed ZrOCl₂·8H₂O aqueous solution. High-resolution transmission electron microscopy reveals that a highly conformal and uniform ZrO₂ shell was deposited on NDs by this simple method. The coating obtained at 90 °C without further calcination was mainly composed of mo...
متن کاملHighly dispersed MoO(x) on carbon nanotube as support for high performance Pt catalyst towards methanol oxidation.
HPMo self-assembly on carbon nanotubes followed by decomposition is used to fabricate highly dispersed MoO(x)/CNTs as a support for high performance of a Pt catalyst towards methanol oxidation.
متن کاملBoron-doped carbon nanotube-supported Pt nanoparticles with improved CO tolerance for methanol electro-oxidation.
Boron doping into carbon nanotubes improves the CO tolerance and increases the utilization efficiency of the supported Pt nanoparticles. Boron doping leads to a uniform deposition of Pt nanoparticles and also facilitates the removal of CO from the Pt surface, resulting in an increase in the electrocatalytic activity for methanol oxidation.
متن کاملElectro-Catalytic Activities of Binary Nano-Composites of Pt and Nano- Carbon/Multiwall Carbon Nanotube for Methanol Electro-Oxidation
Binary nano-composites of Pt and nano-carbon (NC) and Pt and multiwalled carbon nanotube (MWCNT) have been prepared with varied compositions ranging between 20 and 80wt% Pt and investigated them as electrocatalysts for methanol oxidation. The study shows that with the increase in wt% of NC, the apparent electro-catalytic activity of the composite catalyst increases initially, reaches maximum at...
متن کاملActive and stable platinum/ionic liquid/carbon nanotube electrocatalysts for oxidation of methanol
Platinum (Pt) nanoparticles (NPs) on carbon nanotubes (CNTs) have been prepared from PtCl6 2 ions through a facile ionic liquid (IL)-assisted method and used for methanol oxidation. 1-Butyl-3-methylimidazolium (BMIM) with four different counter ions (PF6 , Cl , Br , and I ) has been tested for the preparation of Pt/IL/CNT nanohybrids, showing the counter ions of ILs play an important role in th...
