Electrochemical study of the first layers of oxide formed on copper in carbonate - bicarbonate solutions

, 2003
The electrochemical behavior of copper electrodes in different carbonate bicarbonate solutions, with emphasis in the potential region of Cu(I) aide electroformation and electro-reduction has been studied by voltammetric techniques, scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS).

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

Carbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy

The Effect of Water Management and Cell Compression in Bipolar Membrane CO2 Electrolysis to CO

Carbon Energy, EarlyView.
In‐operando neutron imaging uncovers water management challenges in bipolar membrane CO2 electrolysis: Internal water generation floods the cathode, while compression dictates membrane and gas diffusion electrode integrity. Strategic adjustments are applied in this work: dry gas feed and mechanical support of the gas diffusion electrode enable stable ...
