Facile synthesis of urchin-like RuCu and hollow RuCuMo nanoparticles and preliminary insight to their formation process by cyclic voltammetry

Abstract

The urchin-like RuCu and hollow RuCuMo nanocrystals were synthesized by one-pot chemical reduction method. The formation process of these nanocrystals was traced by cyclic voltammetry.

Facile Synthesis of PdCuRu Porous Nanoplates as Highly Efficient Electrocatalysts for Hydrogen Evolution Reaction in Alkaline Medium

“…First, previous study indicated that only Cu 2+ ions cannot be reduced by benzyl alcohol [40]. On the contrary, Ru nanoparticles are often obtained through the reduction of Ru 3+ ions by polyol [40][41][42]. In this work, the presence of the Pd nanoplates facilitates the reduction of Cu 2+ ions to Cu atoms prior to Ru precursor due to the well-known underpotential deposition (UPD) [43].…”

“…For comparison, the introduction of Cu here results in the formation of the porous nanoplates, indicating the critical role of Cu. First, previous study indicated that only Cu 2+ ions cannot be reduced by benzyl alcohol [40]. On the contrary, Ru nanoparticles are often obtained through the reduction of Ru 3+ ions by polyol [40][41][42].…”
