Special Issue Information

Dear Colleagues,

We are pleased to invite you to submit your research papers to the Special Issue of Inorganics titled “Single Atom Alloys: Modern Trends in Preparation and Application”.

Single-atom alloys (SAAs) are a type of single-site catalyst containing catalytically active elements (Pd, Pt, Rh, Ru) that are atomically dispersed in more inert but more selective host metals (Ag, Au and Cu). Alloying the reactive metals of Pt group with less-reactive hosts provides more selective chemical reactions, improved resistance to carbon monoxide poisoning, greater resistance to deactivation by coking and significant cost savings for catalyst manufacturers. Due to their unique atomic structure and exceptional catalytic selectivity, SAAs demonstrate promising potential as a new class of excellent catalysts for various chemical reactions in laboratory, pilot scale and industrial application. SAAs currently exhibit unique reactivity for the selective hydrogenation of hydrocarbons and unsaturated aldehydes, the dehydrogenation of hydrocarbons and alcohols, C–C and CO– coupling reactions, the hydrogenolysis of biomass-type molecules, and C–H activation.

This Special Issue will focus on recent advances in the synthesis and physicochemical characterization of SAAs for a wide variety of catalytic applications, as well as studies on the structure of SAAs, experimental and computational studies revealing the relationship between the isolated metal atoms, as well as their catalytic performance and mechanisms of reaction. Studies focusing on novel synthesis techniques of SAAs for industrial scale-up are of interest as well. We encourage of all types of submissions, including communications, original research articles, and reviews related to SAAs approaching practical application.

We look forward to receiving your contributions.

The effect of support on the performance of Pd1Ag10/Al2O3 and Pd1Ag10/CeO2–ZrO2 catalysts in the selective hydrogenation of diphenylacetylene (DPA) was studied. Characterization of the catalyst by DRIFTS-CO and HRTEM revealed the formation of a PdAg single-atom alloy (SAA) structure on the surface of PdAg nanoparticles, with Pd1 sites isolated by Ag atoms. It was found that the use of CeO2–ZrO2 as a carrier makes it possible to increase the activity of the Pd1Ag10 catalyst by a factor of three without loss of selectivity compared to the reference Pd1Ag10/Al2O3. According to the HRTEM data, this catalytic behavior can be explained by an increase in the dispersion of Pd1Ag10/CeO2–ZrO2 compared to its Pd1Ag10/Al2O3 counterpart. As evidenced by DRIFTS-CO data, the high selectivity of the Pd1Ag10/CeO2–ZrO2 sample presumably stems from the stability of the structure of isolated Pd1 sites on the surface of SAA Pd1Ag10/CeO2–ZrO2.
