A Dual Bed Approach to Photocatalytic Water-Splitting

We are engaged in a research effort to develop an efficient, affordable,
direct photoconversion scheme for generating H2 from H2O using sunlight.
The approach is to use seconductors in powdered form in a dual bed
configuration, breaking down the energy requirement for water-splitting
into a 2-stage process, allowing for better usage of the solar spectrum,
and enabling separate production of H2 and O2. Various metal oxides and
phosphides have been considered as photocatalysts for O2 and H2 evolution,
respectively. The use of various classes of organic pigments as
substitute photocatalysts is also being pursued. Results obtained to date
will be reported.
