TL;DR: Pd-Pt bimetallic nanodendrites consisting of a dense array of Pt branches on a Pd core by reducing K2PtCl4 with L-ascorbic acid in the presence of uniform Pd nanocrystal seeds in an aqueous solution showed relatively large surface areas and particularly active facets toward the oxygen reduction reaction (ORR), the rate-determining step in a proton-exchange membrane fuel cell.

TL;DR: The first synthesis of NiMo nitride nanosheets on a carbon support (NiMoNx/C) is reported, and the high HER electrocatalytic activity of the resulting NiMoNX/C catalyst with low overpotential and small Tafel slope is demonstrated.

TL;DR: This work has developed a method for preparing highly uniform monodisperse nanocrystals of Cu(2)O, and confirmed the thin layer of CuO, which is blue-shifted, and appears to increase in energy as a function of decreasing particle size.

TL;DR: It is demonstrated that, in addition to the well-known catalytically active edge sites, sulfur vacancies provide another major active site for the HER, while the catalytic activity of grain boundaries is much weaker.

TL;DR: In this article, the shape control of Pd nanocrystals with well-controlled shapes in aqueous solutions is discussed. But the shape of the final shape taken by a nanocrystal is determined by the twin structures of seeds and the growth rates of different crystallographic facets.
