One layer is enough: A new catalyst comprising a platinum monolayer on tungsten monocarbide (WC) could lead to inexpensive and efficient (photo)electrochemical production of molecular hydrogen (see scheme). The system uses far less platinum than conventional platinum-foil electrodes but is just as effective.
