Thermodynamic Stability and Site‐Specific Distribution of Graphitic and Pyridinic Nitrogen in Graphene Moiré on Ru(0001)

open access: yesAdvanced Materials Interfaces, EarlyView.
Nitrogen doping on Ru(0001) is investigated using ion implantation and annealing, tuning the distribution of graphitic (GN) and pyridinic (PN) nitrogen sites. STM, XPS, and DFT identified the structure and site distribution, and a thermodynamic phase diagram showed that GN is most stable at the Atop region, while PN preferred boundaries between FCC and

Fabrication and Characterization of MWCNTs Decorated ZnO Nanograins Based Sensor for Enhanced Performance Toward CO2 Gas

open access: yesAdvanced Materials Interfaces, EarlyView.
The present work is concerned with the fabrication of CO2 sensors based on MWCNTs/ZnO material, which is obtained by RF magnetron sputtering and electron‐beam deposition methods. The sensor exhibits highly sensitive and selective behavior, high repeatability, and temporal stability at low CO2 concentrations.

Spectroelectrochemical Analysis of Oxygen Evolution by Nickel Hydroxide: Role of Oxygen Vacancies, Charge Transfer, and Silk Fibroin

open access: yesAdvanced Materials Interfaces, EarlyView.
Silk fibroin enhances the oxygen evolution reaction (OER) on Ni(OH)₂ catalysts by stabilizing oxygen vacancies and promoting charge transfer. Operando spectroelectrochemical analyses reveal a Mars–van Krevelen‐type mechanism involving lattice oxygen and superoxide intermediates.
