Alloying Cu, Fe, and Co in Ni/YSZ Electrodes for High‐Temperature CO2 Electrolysis: Impact on TPB Density, Activity, and Carbon Deposition Resistance

Carbon Energy, EarlyView.
Systematic alloying of Ni with Cu, Fe, and Co in Ni/YSZ electrodes modifies active site density up to 43%, decreases activation energies by up to 44%, and reduces carbon deposition fourfold. Cu–Ni alloy is among the most promising alloy catalysts for electrochemical CO2 reduction in SOECs.

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Grafting Nanolayers of Ni and Co Catalysts Around the Edges of Hierarchical Zeolite 13X by Leveraging the Crystal's Defects for CO2 Methanation

Carbon Energy, EarlyView.
The deactivation of nickel‐based catalysts at high temperatures poses a significant challenge in CO2 methanation processes. To address this, a strong metal–support interaction between nickel and the support was engineered by exploiting the crystal defects present in hierarchical porous zeolite 13X.

KI‐Doped α‐Mo2C Stably Catalyze Near‐Equilibrium CO2 to CO Beyond 1000 Hours

Carbon Energy, EarlyView.
Through iodine doping and effective stabilization of surface oxygen content, KI‐doped α‐Mo2C achieves a sustained equilibrium yield ratio of 0.95 over 1000 h at 400°C and 4 bar in reverse water–gas shift (RWGS) reaction. Furthermore, the catalyst has been successfully scaled up to the kilogram level, indicating considerable potential for industrial ...
