Synergy effect of graphite silica and TiO2 on photocatalytic hydrogen production
The photocatalytic production of hydrogen gas from water-methanol mixtures was performed in contact with a suspended mixture of titanium dioxide (TiO2) and graphite silica (GS), one of natural minerals. A drastic synergy effect for hydrogen production was found for GS in collaboration with TiO2. It is suggested that the clay fraction in GS is one of the key components for the synergy effect.
