Abstract
One of the challenges for tlie solar hydrogen production is the development of efficient catalyst, made
from earth abundant el ments which can be integrated into light-harvesting photochemical devices.
The only natural system established to photooxidise water using visible light .is a catalytic core
consisting of a CaMn.Ox cluster known as the water oxidation centre (WOC) of Photosystem II, and is
thus an inspiration for catalyst design. Recently, we reported the photon assisted electro-oxidation of
water using tetranuclear Mn-oxo cluster ([Mn404L6t, L=(MeOPhhPOi), inspired by the WOC.
Efficient electro-oxidation of water was achieved at a potential of 1.2 V (vs SHE) on incorporation
within electrode bound Nafion membranes and irradiation with visible Ught. The present article
summarises the progress we have made on photo-electrochemical cells that utilise catalysts based on
the earth abundant manganese. Solar water oxidation has been achieved in a single multilayer device,
combining the water oxidation catalyst with light absorbing dyes, and in tandem devices in which
catalytic water electrolysis is driven by photo-voltaic cells, specifically two dye sensitised solar cells.
