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 ...

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction
