Enhanced light-induced hydrogen evolution reaction by supramolecular systems of cobalt(II) and copper(II) octaethylporphyrins on glassy carbon electrodes

Chemically modified glassy carbon electrodes formed by π-stacking of commercial cobalt (II) and copper (II) porphyrins have been used as stable and efficient electrocatalytic system for the hydrogen evolution reaction at pH 7.0, as reported in a previous work. In this work, it has been found that wh
