Large-scale production of peroxide using these EEG samples are conducted using bulk electrolysis. EEG-coated and uncoated graphite paper was employed for the electrochemical production of

• ; Introduction A combination of multiple nanostructured materials in one hybrid systems often allows a synergistic improvement of the properties of the individual components. This is important for many practical fields and particularly for electrochemical production of energy [1], where the electrodes should

N2 adsorption is

For a more reduced oxygen skin, e.g., the Mo13O6 nanocluster, the energetics of the electrochemical production of ammonia are much more diverse. Here, two routes are
