Resumo

Catalysis of electrochemical reactions at derivatized electrode surfaces may offer an attractive alternative to homogeneous catalysis as far as problems related to separation between catalyst and product and to minimizing the required amount of catalyst are concerned. In this context, several points are addressed regarding catalysis at a monolayer derivatized electrode: (1) catalytic efficiency in terms of preparative scale electrolysis and effect of side reactions destroying the active form of the catalyst;(2) comparison between monolayer derivatized electrode and homogeneous catalysis for systems having the same activation free energy; (3) the problem of redox (outer-sphere) catalysis at monolayer derivatized electrodes compared to naked conventional electrodes is discussed in terms of the current theories of adiabatic outer-sphere electron transfer involving the possible effects of collision frequency factors, image force energy and electrostatic work terms.
