Italy SUMMARY We should especially precise that to our knowledge, the PS nanostructures are
original and unique nanomaterial type in which several possibilities for
hydrogen
storage and production can be simultaneously realized: 1) physisorption; 2)
chemisorption; 3) hydrogen incorporation in crystalline nanostructure; 4)
hydrogen
production due to oxidation. Therefore, general study of this nanomaterial as
The main aim of our project will be study of porous silicon (PS) nanostructures

new hydrogen reservoirs.
The main objectives of our project are:
1) quantitative analysis of hydrogen amount chemically bound to the specific
surface of the nano-PS structures;
2) enhancement of the hydrogen amount which can be stored in PS
nanostructures up to 10 mass% due to elaboration of new approaches allowing
reversible storage;
3) elaboration of original technological ways allowing in future mass production
of
the PS-based hydrogen reservoirs at an industrial level;
4) elaboration of efficient ways for hydrogen desorption from the PS
nanostructures at low temperatures (<200°C) and at atmospheric pressure;
5) ensuring of high reproducibility and stability of hydrogen storage in the PS
nanostructures at room temperature and atmospheric pressure.
hydrogen reservoir is a new and extremely promised research work of the first
order importance.
