Highly Selective Electroreduction of CO2 to CH4 on Cu–Pd Alloy Catalyst: the Role of Palladium‐Adsorbed Hydrogen Species and Blocking Effect

Advanced Science, EarlyView.
The blocking effect induced by the Pd atom would interrupt the C─C coupling reaction by increasing the intermolecular distance between adjacent *CO and *CHO intermediates adsorbed on the Cu atoms when introduced Pd into the Cu lattices and the *CO protonation effect of palladium‐adsorbed *H species boosts the CH4 formation on the Cu–Pd alloy catalyst ...

Supercritical CO2 Activation Enables an Exceptional Methanol Synthesis Activity Over the Industrial Cu/ZnO/Al2O3 Catalyst

Advanced Science, EarlyView.
A supercritical CO2 activation strategy is demonstrated for the ternary industrial Cu/ZnO/Al2O3 catalyst to synchronously perfect the strong metal–support interaction‐induced Cu–ZnOx interfacial and exposed Cu surface sites by manipulating the adsorbent diffusion kinetics. A dual‐response pathway in methanol synthesis is unraveled.

Dual‐Atom Catalyst Au@S‐rGO for Rapid and Highly Sensitive Electrochemical Detection of Fentanyl in Serum

Advanced Science, EarlyView.
This study develops an Au/S‐doped reduced graphene oxide (Au@S‐rGO) sensor for rapid fentanyl detection. DFT simulations and structural analysis confirm atomically dispersed Au/S configurations, enhancing catalytic activity. The sensor achieves a 9.7 nmol L−1 detection limit, 98–104% recovery in human serum, and 85.7–93.6% consistency with mass ...

The Function of Photocatalytic Performance and Carrier Separation Efficiency Tuned by Doping Content in Homogeneous Photocatalysts

Advanced Science, EarlyView.
A doping model of homogeneous photocatalysts of TiO2 is constructed to directly show the mapping relationship between carrier separation efficiency and photocatalytic performance. TRPL, KPFM, fs‐TAS measurements further quantify the carrier dynamics process. The photocatalytic performance of this series samples is dominated by the optimal conditions of

Robust Controlled Degradation of Enzyme Loaded PCL‐Based Fibrous Scaffolds Toward Scarless Skin Tissue Regeneration

Advanced Science, EarlyView.
A novel biodegradable wound dressing (E‐PCLs) based on polycaprolactone (PCL) and an enzyme complex (RHP‐BCL) is developed using a fiber microfluidic electrospinning technique. The dressing achieves complete degradation within 14 days, eliminates microplastic residues, and promotes scar‐free healing (99% in 21 days).

Surface Charge Transfer Enhanced Cobalt‐Phthalocyanine Crystals for Efficient CO2‐to‐CO Electroreduction with Large Current Density Exceeding 1000 mA cm−2

Advanced Science, EarlyView.
A spray‐growth method is developed to rapidly load cobalt‐phthalocyanine crystals onto carbon paper (CoPc/CP). The electrode maintains > 90% CO selectivity across potentials (−0.57–−1.32 V vs. RHE), achieving a record JCO (−1034 mA cm−2), ultra‐high mass activity (5180 A g−1), and excellent stability (145 h@−150mA cm−2), surpassing all reported Pc ...
