Journal ArticleDOI
Synthesis of Tetrahexahedral Platinum Nanocrystals with High-Index Facets and High Electro-Oxidation Activity
TL;DR: Platinum NCs of unusual tetrahexahedral (THH) shape were prepared at high yield by an electrochemical treatment of Pt nanospheres supported on glassy carbon by a square-wave potential to exhibit much enhanced catalytic activity for equivalent Pt surface areas for electro-oxidation of small organic fuels such as formic acid and ethanol.
Journal ArticleDOI
Nanomaterials of high surface energy with exceptional properties in catalysis and energy storage
TL;DR: This critical review presents a review of the progress made for producing shape-controlled synthesis of nanomaterials of high surface energy using electrochemical and wet chemistry techniques and discusses important nanommaterials such as nanocrystal catalysts based on Pt, Pd, Au and Fe, metal oxides TiO(2) and SnO( 2), as well as lithium Mn-richMetal oxides.
Journal ArticleDOI
Electrochemical adsorption behaviour of platinum stepped surfaces in sulphuric acid solutions
TL;DR: In this article, a technique for the orientation, cutting and polishing of small platinum single-crystal planes is given whose angular accuracy is within 3 min. This is required for the preparation of stepped surfaces with a well-controlled step density.
Journal ArticleDOI
Phenylenediamine-Based FeNx/C Catalyst with High Activity for Oxygen Reduction in Acid Medium and Its Active-Site Probing

TL;DR: It is found that the ORR activity of PmPDA-FeN(x)/C is not sensitive to CO and NO(x) but can be suppressed significantly by halide ions and low valence state sulfur-containing species in acid medium.
Journal ArticleDOI
Platinum Metal Catalysts of High-Index Surfaces: From Single-Crystal Planes to Electrochemically Shape-Controlled Nanoparticles
TL;DR: The Natural Science Foundation of China as discussed by the authors [20673091, 20433060, 20503023, 20873113, 20833005], Mnistry of Science and Technology of China [2009CB220102, 2007DFA40890]
