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

open access: yesCarbon 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.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.

Crystal growth of sulfide materials from alkali polysulfide liquids [PDF]

open access: yes
The fluids experiment system was designed for low temperature solution growth, nominally aqueous solution growth. The alkali polysulfides, compositions in the systems Na2S-S and K2S-S form liquids in the temperature range of 190 C to 400 C.

Nanofiber‐Confined 2H‐NbSe2 With a Li2S Activation Interface for 10 C Fast‐Charging Lithium–Sulfur Batteries

open access: yesEcoEnergy, EarlyView.
A flexible carbon nanofiber‐confined 2H‐NbSe2 membrane (2H‐NbSe2@CNFM) serves as an electrocatalytic reactor to construct a Li2S activation interface, enabling rapid and reversible Li2S conversion. This tailored interface markedly enhances rate performance and cycling stability, offering a robust strategy for advancing high‐power Li‐S batteries ...
