Platinum Nanoparticles Decorated IrO2@MWCNT as an Improved Catalyst for Oxygen Evolution Reaction

摘要

In this paper, IrO2 nanoparticles supported on multi-walled carbon nanotubes (MWCNTs) are synthesized via a facile hydrothermal method and calcination process at different temperature. Platinum nanoparticles decorated IrO2@MWCNT- 400°C are prepared by chemical reduction method. The influence of MWCNTs and Pt on physicochemical properties and oxygen evolution reaction (OER) activity of IrO2@MWCNT composites were studied via transmission electron microscope (TEM), X-ray diffraction (XRD), Raman spectra, thermogravimet- ric analysis (TGA), X-ray photoelectron spectroscopic (XPS) and electrochemical methods.
