Single-atom catalysts are defined by their structure where single atoms are dispersed on a suitable substrate, maximizing the exposure of active sites. Unlike nanoparticles or bulk materials, SACs ...
Single-atom catalysts (SACs) — which involve isolated, single metal atoms — have emerged as the next generation of catalysts. Compared to nanoparticles or clusters, SACs provide great activity ...
Scientists have created the world's thinnest gold leaf, which is just a single atom thick ... with the gold atoms coagulating into nanoparticles as soon as the support was removed.
