DOI: 10.1002/advs.202503561

Abstract: Atomic layer modulation (ALM) presents a novel approach for controlling the stoichiometry of platinum‐ruthenium (PtRu) alloys rather than a tedious atomic layer deposition (ALD) supercycling multielement ALD process. This method sequentially pulses dimethyl‐(N,N‐dimethyl‐3‐butene‐1‐amine‐N)platinum (C8H19NPt, DDAP)… read more here.

DOI: 10.1002/smll.202302149

Abstract: The sluggish kinetics of the methanol oxidation reaction (MOR) with PtRu electrocatalyst severely hinder the commercialization of direct methanol fuel cells (DMFCs). The electronic structure of Pt is of significant importance for its catalytic activity.… read more here.

DOI: 10.1016/j.apsusc.2017.10.026

Abstract: Abstract Platinum-ruthenium (PtRu) nanocubes and PtRu/Ru heterostructure via epitaxial growth were synthesized by varying the amount of Ru precursor. As model catalysts, the PtRu/Ru heterostructure demonstrated the highest catalytic performance in electrooxidation of methanol, which… read more here.

DOI: 10.1016/j.jcat.2020.02.028

Abstract: Abstract We successfully prepared 1.98 wt% PtRu nanoparticles (NPs) partially embedded in the skeleton of three-dimensionally ordered macroporous Ce0.7Zr0.3O2 (denoted as 1.98PtRu@3DOM CZO) using the polymethyl methacrylate-templating and ethylene glycol reduction methods. For comparison purposes, we… read more here.

DOI: 10.1016/j.jcis.2017.03.026

Abstract: A facile, environment-friendly and one-pot synthesis method for the preparation of high performance PtRu electrocatalysts on the multiwalled carbon nanotubes (MWCNTs) is reported. Herein, bimetallic PtRu electrocatalysts are deposited onto polydopamine (Pdop) - functionalized MWCNTs… read more here.
