The most accepted mechanism of NRR contains associative and dissociative paths. Firstly, the nitrogen molecules are adsorbed on the catalyst surface and then the hydrogenation process proceeds. As with CRR, the NRR involves multiple intermediates, and the HER is a major competing reaction, making selectivity a great challenge. In accordance with the general features of this invention the .anode hook and sus pending bar are formed with surfaces which provide for contact between them at a point or points of small area with a pressure equal to the full weight of the suspended anode.

- The anode, which bears the titania dioxide layer, will then appear negatively charged from the accumulation of electrons, whilst the cathode appears positively charges by the opposite accumulation of holes.

- The individual layers of TiS2, which consist of Ti-S bonds, are bounded together by relatively weak intermolecular van der Waals forces.

- The space left between the two electrodes is filled with an electrolyte that ensures charge transportation through a redox couple, typically iodide/tri-iodide.
- The positive terminal of the solar cell, the cathode, is often coated with a catalytic material for electron transfer.
This means the oxidized dye molecule must find a new electron as fast as possible. From a kinetic standpoint, the fastest route back to the dye for the electron is to travel through the external circuit. Injected electrons migrate through the titanium dioxide particles and reach the TCO glass of the anode, the negative terminal of the solar cell.
