Abstract Atomic interface regulation is thought to be an efficient method adjust the performance of single atom catalysts. Herein, a practical strategy was reported rationally design copper atoms coordinated with both sulfur and nitrogen in metal-organic framework derived hierarchically porous carbon (S-Cu-ISA/SNC). The atomic configuration site S-Cu-ISA/SNC detected unsymmetrically arranged Cu-S 1 N 3 moiety. catalyst exhibits excellent oxygen reduction reaction activity half-wave potential...
The engineering coordination environment offers great opportunity in performance tunability of isolated metal single-atom catalysts. For the most popular metal–Nx (MNx) structure, replacement N atoms by some other with relatively weak electronegativity has been regarded as a promising strategy for optimizing an active center and promoting its catalytic performance, which is still challenge. Herein, we proposed new synthetic situ phosphatizing triphenylphosphine encapsulated within...

We discover that an Sb single atom material consisting of Sb–N<sub>4</sub> moieties anchored on N-doped carbon nanosheets can serve as a CO<sub>2</sub>RR catalyst to produce formate with high efficiency.
Abstract Main‐group element indium (In) is a promising electrocatalyst which triggers CO 2 reduction to formate, while the high overpotential and low Faradaic efficiency (FE) hinder its practical application. Herein, we rationally design new In single‐atom catalyst containing exclusive isolated δ+ –N 4 atomic interface sites for electroreduction formate with efficiency. This exhibits an extremely large turnover frequency (TOF) up 12500 h −1 at −0.95 V versus reversible hydrogen electrode...
Oxygen-involved electrochemical reactions are crucial for plenty of energy conversion techniques. Herein, we rationally designed a carbon-based Mn–N2C2 bifunctional electrocatalyst. It exhibits half-wave potential 0.915 V versus reversible hydrogen electrode oxygen reduction reaction (ORR), and the overpotential is 350 mV at 10 mA cm–2 during evolution (OER) in alkaline condition. Furthermore, by means operando X-ray absorption fine structure measurements, reveal that bond-length-extended...
Peanut shells were transformed into porous carbon with a high surface area through simple ZnCl<sub>2</sub>-molten salt synthesis process.
Copper-based materials can reliably convert carbon dioxide into multi-carbon products but they suffer from poor activity and product selectivity. The atomic structure-activity relationship of electrocatalysts for the selectivity is controversial due to lacking systemic multiple dimensions operando condition study. Herein, we synthesized high-performance CO2RR catalyst comprising CuO clusters supported on N-doped nanosheets, which exhibited high C2+ Faradaic efficiency 73% including decent...

With more flexible active sites and intermetal interaction, dual-atom catalysts (DACs) have emerged as a new frontier in various electrocatalytic reactions. Constructing typical p-d orbital hybridization between p-block d-block metal atoms may bring avenues for manipulating the electronic properties thus boosting activities. Herein, we report distinctive heteronuclear dual-metal atom catalyst with asymmetrical FeSn dual embedded on two-dimensional C2N nanosheet (FeSn–C2N), which displays...
Owing to their synergistic interactions, dual-atom catalysts (DACs) with well-defined active sites are attracting increasing attention. However, more experimental research and theoretical investigations needed further construct explicit understand the synergy that facilitates multistep catalytic reactions. Herein, we precisely design a series of asymmetric selenium-based comprise heteronuclear SeN2–MN2 (M = Fe, Mn, Co, Ni, Cu, Mo, etc.) for efficient oxygen reduction reaction (ORR)....

The carbon-neutral photocatalytic CO2 reduction reaction (CO2RR) enables the conversion of into hydrocarbon fuels or value-added chemicals under mild conditions. Achieving high selectivity for desired products CO2RR remains challenging.
