NANO-STRUCTURED MATERIALS FOR A HYDROGEN ECONOMY

摘要

In this paper, we have presented selected nano-structured materials for the conversion and storage of solar energy. Process conditions for CVD can be selected to deposit thin films of anatase TiO_2 with fractal surface morphologies, which can be used for an ETA solar cell. ALD is an excellent tool to design novel nano-structured 3D solar cells. The presently-achieved conversion efficiency of 4% is double that of the current ETA solar cell. Nano-structured metal oxide catalysts improve the kinetics of hydrogen sorption in metal hydrides. The mechanism is yet not understood, but enhanced point defect densities play an important role. A new proton-conducting solid electrolyte has been tested in a Nernst hydrogen sensor.
