TLDR
In this article, evidence was provided that silver zeolites can be used for the decomposition of water into hydrogen and oxygen; the process consists of a photochemically induced reduction of the zeolite, followed by an oxidative thermal desorption of hydrogen.Abstract:

Photochemical production of hydrogen and oxygen from water: A review and state of the art
TL;DR: A survey of the different attempts for complete water splitting into hydrogen and oxygen is also made in this article, which is based on different approaches: (i) multimolecular systems, (ii) systems involving a supramolecular structure of polyad type, and (iii) systems incorporated in organized and constrained or confined media.

TL;DR: In this paper, the photocatalytic reactivity of transition metal oxides and ions in their efficiency and selectivity were found to depend strongly on their local structures, which are controlled by the unique and restricted framework structures of zeolites.

TL;DR: Analysis of the fluorescent properties in combination with ESR spectroscopy suggests that a Ag(6)(+) cluster with doublet electronic ground state is associated with the appearance of the 690-nm emitter, having a decay of a few hundred microseconds.

Visible light-induced cleavage of water into hydrogen and oxygen in colloidal and microheterogeneous systems
TL;DR: In this article, a detailed analysis of methods to obtain highly active and selective catalysts, and the performance of bifunctional redox catalysts in cyclic water cleavage systems by visible light is described.
