Currently, more than 86% of global energy consumption is still mainly dependent on
traditional fossil fuels, which causes resource scarcity and even emission of high amounts of …

Electrocatalysis underpins the renewable electrochemical conversions for sustainability,
which further replies on metallic nanocrystals as vital electrocatalysts. Intermetallic …

Isolated atoms featuring unique reactivity are at the heart of enzymatic and homogeneous
catalysts. In contrast, although the concept has long existed, single-atom heterogeneous …

Supported single-metal atom catalysts (SACs) are constituted of isolated active metal
centers, which are heterogenized on inert supports such as graphene, porous carbon, and …

Atomically dispersed metal catalysts (ADCs), as an emerging class of heterogeneous
catalysts, have been widely investigated during the past two decades. The atomic dispersion …

Abstract Single‐atom‐alloys (SAAs), as an emerging kind of materials, combine the
advantages of alloy and single‐atom catalysts. The full atomic utilization of active sites and …

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-atom catalysts (SACs) with atomically dispersed metals have emerged as a new
class of heterogeneous catalysts and have attracted considerable interest because they …

Abstract Ruthenium (Ru)‐based catalysts, with considerable performance and desirable
cost, are becoming highly interesting candidates to replace platinum (Pt) in the alkaline …

In recent years, proton exchange membrane (PEM) fuel cells have regained worldwide
attention from academia, industries, investors, and governments. The prospect of PEM fuel …
