Project Objectives 

Towards the aim of the proposed research the following objectives have been set:

1. Development of efficient Pt-Ni, Pt-Cu, Ir-Ni, Ir-Cu, Pt-Ti and Ir-Ti cathodes and anodes of minimal precious metal content,

by means of a novel galvanic replacement/deposition techniques.

2. Development of novel TiO2–based photoanodes of improved visible light activity and conductivity by means of

hydrothermal/gas-phase synthesis.

3. Development of bi-functional IrO2/TiO2 anodes/photoanodes for variable illumination conditions.

4. Theoretical prediction of best binary metal/metal oxide catalyst combinations for the relevant hydrogen evolution, oxygen

evolution (electrolyzer) and hydrogen oxidation (compressor) reactions.

5. Testing optimum electrocatalysts/photo-electrocatalysts in electrochemical hydrogen compression cells and water photo-

electrolyzers.

6. Produce a combined prototype water (photo)electrolysis/ pure hydrogen compression unit.
