Synergistic Fe–Si Dual‐Site Pathway Engineering in Biomass‐Derived Carbon Matrix for High‐Performance Oxygen Reduction Reaction

Carbon Energy, EarlyView.
We report a dual‐atomic Si–Fe–N–C catalyst synthesized from nitrogen‐rich pinecones and an Fe porphyrin precursor. The inherent Si and N in pinecones form a porous Si–N–C framework that stabilizes Fe atoms during pyrolysis, yielding robust Si–Fe dual sites.

Recent Progress on Fullerene–Based Functional Materials for Energy Conversion

Carbon Energy, EarlyView.
A schematic illustration summarizing the classification, and photo‐/electro‐‐/thermo‐catalysis and energy storage applications of C60 and derivatives. ABSTRACT Efficient energy conversion and environmental protection are still constrained by rapid carrier recombination, unstable interfaces, limited active site, and so on. Owing to the unique electronic

Phase‐Pure 2D Interfacial Perovskite Passivation for Stable and Efficient Photovoltaics

Carbon Energy, EarlyView.
Phase‐pure 2D interfacial passivation eliminates mixed‐phase energetic disorder, establishes favorable band alignment, and suppresses interfacial non‐radiative recombination. This review elucidates deterministic phase‐purity control, defect and lattice reconstruction mechanisms, and scalable manufacturing strategies, highlighting how phase‐pure 2D/3D ...

Boosting Electron‐Hole Charge Separation in CO2 Photoreduction through Fluoroporphyrin‐Linked Nickel(II)‐Acetylide Frameworks

Carbon Energy, EarlyView.
A NiII‐acetylide framework, H2TFPP‐Ni‐AF, demonstrates outstanding photocatalytic CO2 reduction performance: 13.16 mmol h−1 g−1 of CO with 97.9% selectivity. Synergistic interactions, including d‐p orbital hybridization within NiII‐bis(acetylide) moieties ( − C ≡ C−NiII(PBu3)2 − C ≡ C − ) and the efficient charge transport afforded by π‐conjugated ...

Hole‐Selective Self‐Assembled Monolayers Overlaid on NiOx or PEDOT:PSS for Tin‐Based Perovskite Solar Cells – An Overview of Recent Characterization Methods

Chemistry – A European Journal, EarlyView.
Successfully applying self‐assembled monolayers with hole‐selectivity for lead‐free tin perovskite solar cells requires judicious investigation with appropriately powerful characterization methods, in addition to efforts in the development of new materials and processing.
