The design of efficient copper(Cu)-based catalysts is critical for CO2 electroreduction into multiple carbon products. However, most Cu-based are favorable ethylene production while selective ethanol with high Faradaic efficiency and current density still remains a great challenge. Herein, we carbon-coated CuOx (CuOx @C) catalyst through one-pot pyrolysis metal-organic framework (MOF), which exhibits selectivity to 46 %. Impressively, the partial reaches 166 mA cm-2 , higher than that...
Graphdiyne exhibits high activity for CO<sub>2</sub> electroreduction reaction and the unique sp–sp<sup>2</sup> hybridization is crucial.
The sluggish kinetics for anodic oxygen evolution reaction (OER) and insufficient catalytic performance over the corresponding Ir-based catalysts are still enormous challenges in proton exchange membrane water electrolyzer (PEMWE). Herein, it is reported that KIr
Abstract Despite the intriguing potential, nano‐socketed Cu/perovskite heterostructures for CO 2 electroreduction (CO RR) are still in their infancy and rational optimization of RR properties is lacking. Here, an effective strategy reported to promote ‐to‐C 2+ conversion over by A‐site‐valence‐controlled oxygen vacancies. For proof‐of‐concept catalysts Cu/La 0.3‐x Sr 0.6+x TiO 3‐δ (x from 0 0.3), vacancy concentrations increase controllably with decreased A‐site valences (or increased x...
The electrocatalytic carbon dioxide (CO2) reduction reaction (CO2RR) is extensively regarded as a promising strategy to reach neutralization. Copper sulfide (CuS) has been widely studied for its ability produce C1 products with high selectivity. However, challenges still remain owing the poor selectivity of formate. Here, Bi/CeO2/CuS composite was synthesized using simple solvothermal method. Bi/CeO2–decorated CuS possessed formate selectivity, Faraday efficiency and current density reaching...
Human sweat has the potential to be sufficiently utilized for noninvasive monitoring. Given complexity of secretion, sensitivity and selectivity monitoring should further improved. Here, we developed an olfactory-inspired separation-sensing nanochannel-based electronic sensitive selective monitoring, which was simultaneously endowed with interferent separation target detection performances. The special strategy imparts functional composite membranes a high 113 mV dec–1 potassium detection....
Copper-based catalysts have been attracting increasing attention for CO2 electroreduction into value-added multicarbon chemicals. However, most Cu-based are designed ethylene production, while ethanol production with high Faradaic efficiency at current density still remains a great challenge. Herein, Cu clusters supported on single-atom dispersed nitrogen-doped carbon (Cux/Cu–N/C) show of ∼40% and partial ∼350 mA cm–2. Quasi in situ X-ray photoelectron spectroscopy operando absorption...
A PtRu/PtNi/C catalyst shows higher CO tolerance than PtNi/C, PtNi–Ru/C and PtRu/C catalysts due to the synergistic effect between PtRu surface PtNi core.

Negative Poisson's ratio (NPR) structures, also known as auxetics, are attracting growing interest due to their unique mechanical properties and a wide range of potential deployment. More attention has been paid explore novel auxetic structures through bionics, lattice cells, or origami. However, the systemic design method NPR not yet matured. Herein, framework is proposed by integrating freedom, actuation, constraint topologies (FACT) theory isogeometric analysis. Based on method, shape...
