How can the Dual‐atom Catalyst FeCo–NC Surpass Single‐atom Catalysts Fe–NC/Co–NC in CO <sub>2</sub> RR? – CO Intermediate Assisted Promotion via a Synergistic Effect

چکیده
Atomically dispersed catalysts are widely adopted in CO2 reduction reaction (CO2RR) due to maximal atomic utilization and high catalytic activity. Dual-atom (DACs), with more active sites distinct electronic structures compared single-atom (SACs), may exhibit diverse performance. Herein, the DAC FeCo–NC SAC Fe–NC/Co–NC employed as probes explore DACs advantage CO2RR. Results show that moderate interaction between dual-atom center N coordination balances structural stability CO is only product on Fe–NC/Co–NC, limiting potentials from −1.22 −1.67 V inhibit further reduction. assisted intermediate exhibits low of −0.64 for both CH3OH CH4, comparable those Cu-based catalysts. Under circumstance applied potentials, CO2RR has greater advantages yielding CH4 than hydrogen evolution severely inhibited. The intrinsic essence can provide large spin-polarization multi-electron transfer capability, rendering intermediates effective geometric modifiers This work highlights a high-performance catalyst toward deep-reduction C1 products elucidates promotion mechanism via synergistic effect.

Can ISPs and Overlay Networks Form a Synergistic Co-existence?
Overlay networks are becoming increasingly popular for their ability to provide effective and reliable service catered to specific applications [1][2][3]. For instance, this concept has been used in peer-to-peer services like SplitStream, content delivery networks like Akamai, resilient networks like RON and so on. Overlay networks consist of a number of nodes (spanning one or many domains) tha...

Catalytic Co-Homologation of Alkanes and Dimethyl Ether and Promotion by Adamantane as a Hydride Transfer Co-Catalyst
Competitive reactions between C-labeled dimethyl ether (C-DME) and unlabeled alkenes have been used to examine the mechanistic details of chain growth and termination pathways leading to the selective formation of triptane and isobutane by means of the homologation of DME or methanol (Scheme 1). These studies have also provided specific and quantitative evidence for the ubiquitous role of carbe...
متن کاملHOW THE KONDO EFFECT CAN EXIST IN Gd INTERMETALLIC COMPOUNDS
Based on the crystal and magnetic structural properties of some Gd intermetallic compounds, it is shown that with increasing conduction electron concentration, Gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of Kondo Lattice. We suggest that the conduction electrons have gained local character. It is shown that Kondo effect should be observed...
