a single-atom iron catalyst is fabricated by saturated adsorption of trace iron onto zeolitic imidazolate framework-8 (ZIF-8) followed by pyrolysis. Its performance toward catalytic transfer hydrogenation of furfural is comparable to state-of-the-art catalysts and up to four orders higher than ...
Due to its high selectivity and high catalytic activity, a single-atom iron catalyst supported on a single-vacancy (SV) graphene-based substrate (Fe/SV) may be a promising catalyst for NO oxidation. The adsorption characteristics and reaction mechanisms of NO and O2 on the surface of Fe/SV ...
atom iron active center, the catalyst shows a remarkable performance with enhanced kinetics and activity for oxygen reduction in both alkaline and acid media. Moreover, the catalyst shows promise for substitution of expensive platinum to drive the cathodic oxygen reduction reaction in zinc-air ...
Single-atom catalyst, which makes exceptionally efficient use of expensive noble metals and can bring out unique properties, is a new frontier in heterogeneous catalysis, a commonly used catalytic reaction in industry. However, applications of single-atom catalysts are usually compromised by limited cat...
Moreover, we find that the ΔGH* of the Ni309 cluster is −0.37 eV, implying that Ni would be more prone to H2 formation if it is not in the single-atom state (Figure S15). The generality of this method was validated by construction of a cobalt single-atom catalyst supported on ...
The Ir single atoms seem to greatly enhance the reducibility of the FeO(x) support and generation of oxygen vacancies, leading to the excellent performance of the Ir1/FeO(x) single-atom catalyst. The results have broad implications on designing supported metal catalysts with better performance ...

Catalysts with singleatom dispersions are thus highly desirable to maximize atom ef?ciency, but making them is challenging. Here we report the synthesis of a single-atom catalyst that consists of only isolated single Pt atoms anchored to the surfaces of iron oxide nanocrystallites. This single-...
Our Fe single atom catalyst can effectively prevent the N-N coupling step required for Ndue to the lack of neighboring metal sites, promoting ammonia product selectivity. Density functional theory calculations reveal the reaction mechanisms and the potential limiting steps for nitrate reduction on ...
