Abstract

The basic mechanism of titanium dioxide photocatalytic water-splitting for hydrogen production is introduced. The methods to enhance hydrogen production are reviewed, including addition of sacrificial reagent, addition of sodium carbonate, noble metal loading, metal ion doping, anion doping, dye sensitization, semiconductor composition and ion implantation. The mechanism of photocatalyst modification methods and their effects on hydrogen production are discussed. Emphasis is particularly given to anion doping and metal ion-implantation. It can be seen that metal ion-implantation is presently the most effective method to expand light response of titanium dioxide into visible region. The practical consideration oxygen and hydrogen gas separation, is also addressed. Compared with other hydrogen production technologies, photocatalytic water-splitting hydrogen production is a promising technology toward hydrogen economy.
