Superaerophobic Polyethyleneimine Hydrogels Improve Electrochemical Hydrogen Manufacturing by Promoting Bubble Detachment
The scheme for a mechanism of bubble-detachment. a) Normal flat electrode, b) the problems of adhered bubbles, and c) various approaches for the removal of gas bubbles. In (a), R, ρ, g, and λ indicate the dimension of bubbles, the density of a solution, gravitational acceleration constant, and surface tension of a solution, respectively....
