Bubble-induced convection stabilizes the local pH during solar water splitting in neutral pH electrolytes
Keisuke Obata, Fatwa F. Abdi
Abstract
Multiphase multiphysics simulation demonstrates the presence of bubble-induced convection in regions close to the (photo)electrode surface, which suppresses the pH gradient and the resulting concentration overpotential.
