"Hydrogen Production Via Photocatalytic Water Splitting" by Bianca Rusinque
The present PhD thesis reports the modification of titanium dioxide (TiO2) with palladium (Pd), to enhance hydrogen production via water splitting, using 2.0v/v% ethanol as a scavenger. Titanium dioxide was used as photocatalyst, given its ability to absorb photons, producing e-/h+ pairs. Mesoporous TiO2 was synthesized using a soft template, following the sol-gel method, to modify its ...
