Alloying has long been used as a promising methodology to improve the catalytic
performance of metallic materials. In recent years, the field of alloy catalysis has made …

Single-atom alloys (SAAs) play an increasingly significant role in the field of single-site
catalysis and are typically composed of catalytically active elements atomically dispersed in …

Single Pt atom catalysts are key targets because a high exposure of Pt substantially
enhances electrocatalytic activity. In addition, PtRu alloy nanoparticles are the most active …

The complexity of heterogeneous catalysts means that a priori design of new catalytic
materials is difficult, but the well-defined nature of single-atom–alloy catalysts has made it …

Achieving large current density is crucial to the practical application of large-scale hydrogen
production by water splitting, but it is hindered by sluggish and unstable catalysts. Herein, a …

Precise control over the size, shape, composition, structure, and crystal phase of random
alloy and intermetallic nanocrystals has been intensively explored in technologically …

Single-atom precious metal catalysts hold the promise of perfect atom utilization, yet control
of their activity and stability remains challenging. Here we show that engineering the …

High-entropy alloys (HEAs) provide a near-continuous distribution of adsorption energies.
With a minority of sites having optimal properties that dominate the catalysis, the overall …

The establishment of electrocatalysts with bifunctionality for efficient oxygen evolution
reaction (OER) and hydrogen evolution reaction (HER) in acidic environments is necessary …

Proton-exchange-membrane fuel cells (PEMFCs) are attractive next-generation power
