Mechanocatalysis with electrically induced contractile electro-active polymer

One of the largest challenges in heterogeneous catalysis is how to control the adsorption and desorption catalytic cycle on the surface of catalyst. Therefore, the ultimate goal of this study is to design a new heterogeneous catalytic system based on an idea that the surface charge of the solid cata...
