Unlocking Methane Generation via Photo‐Thermal‐Coupled CO2 Hydrogenation by Integrating FeNiCrMnCo Multicomponent Alloy with GaN Nanowires

Advanced Science, EarlyView.
A noble‐metal‐free FeNiCrMnCo multicomponent alloy (MCA) integrated with GaN nanowires achieves efficient photo‐thermal‐coupled CO₂ methanation, delivering a methane production rate of 199 mmol∙g−¹∙h−¹ with 93% selectivity. The system demonstrates exceptional stability and tunable catalytic properties, offering a sustainable pathway for solar‐driven ...

Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

Advanced Science, EarlyView.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

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 ...

Single Cu Atoms Anchored Energetic COFs as Combustion Catalytic Promoters toward Rapid and Concentrated Thermal Decomposition of Ammonium Perchlorate

Advanced Science, EarlyView.
Introducing energetic Cu‐based metal salts into the covalent organic frameworks (COFs) structure, Cu is in single‐atom form anchored to the framework, with energetic anions confined in the COFs structure. The synergistic interaction between single Cu atoms and the anions accelerates the reaction kinetics of ammonium perchlorate (AP) decomposition ...

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 ...
