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 ...

Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

Advanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...

Laser‐Induced Co‐Doped FePS3 with Massively Phosphorus Sulfur Vacancies Nanosheet for Efficient and Highly Stable Electrocatalytic Oxygen Reaction

Advanced Science, EarlyView.
DFT‐guided defect engineering in 2D FePS3 reveals S/P vacancies Co‐doped and exposed Fe sites synergistically enhance OER performance. Laser‐ablation‐induced (Fe0.53Co0.46)PS3 exhibits excellent OER performance (288 mV overpotential, 58.3 mV dec−1 Tafel slope) and outstanding stability (138 h at 10 mA cm−2, 27h at 100 mA cm−2).

Recycling Defunct Lithium‐Ion Battery Cathodes to Quaternary Layered Double Hydroxides for Efficient Oxygen Evolution Reaction

Advanced Science, EarlyView.
Li(Co0.8Ni0.1Mn0.1)O2 and LiFePO4 cathode materials are functional recycled by simple leaching and co‐precipitation methods to synthesize Quaternary iron‐nickel‐cobalt‐manganese hydrotalcites as oxygen‐evolution‐reaction catalysts. The highly disordered structure and strong electronic interactions between metal cations result in excellent catalytic ...
