New electrolyte gels based on quaternised and non-cross-linked linear copolymers according to formula (I), having high efficiency and stability. Further described are the method of production of the said gels, their use in the preparation of photoelectrochemical devices and the devices manufactured therewith.

The present invention relates to a process for the preparation of materials with nanometric dimensions and controlled shape, based on titanium dioxide. The invention also relates to a process for the preparation of titanium dioxide nanorods and nanocubes with anatase phase composition, which are highly suitable for photocatalytic use, in particular for applications involving photovoltaic cells, for example Dye Sensitized Solar Cells (DSSC), photoelectrolysis cells and tandem cells for the conversion of solar energy and the production of hydrogen.
