Abstract

Chiral catalytic activities of electrode surfaces fabricated by magnetoelectrochemical etching without oxygen adsorption in a vertical magnetohydrodynamic (MHD) flow have been theoretically examined. Then, the following points were clarified: under anionic specific adsorption, such activities arise from the screw dislocations of 2D pits. Their chirality is donated by microscopic vortexes termed micro-MHD flows, which are formed on the free surfaces covered with ionic vacancies. As a result, under upward (+) and downward (-) magnetic fields, D (dextrorotatory)- and L (levorotatory)-activities appear, respectively.
