Electrocatalysis

The basic principle of modulating the electrocatalysis by the spatial structures of catalysts is shown in Figure 1, where two common factors, mass transfer and the electric field distribution, are considered. First, the adhesion of gas product/reactant bubbles limits the mass transfer rate to catalysts (Figure 1a)..
