Photocatalytic H2 generation from aqueous ammonia solution using ZnO photocatalysts prepared by different methods
Original language description
ZnO photocatalysts were prepared by thermal annealing (TA) of zinc acetate, by precipitation reaction of zinc acetate with NaOH followed by TA and by precipitation reaction of zinc acetate with NaOH in the presence of UV irradiation followed by TA. The photocatalytic performance was investigated for H2 evolution using aqueous ammonia media under 254 nm UV light. The different used synthetic procedure leading to the formation of different defects and oxygen excess defects in the ZnO lattice were factors influencing photocatalytic production of hydrogen. The highest yields of hydrogen were observed in ZnO prepared by TA of zinc acetate in air. This photocatalyst possesses the lowest concentration of oxygen vacancies causing efficient trapping of electrons. Consequently higher number of electrons in conduction band was available for photocatalytic reaction.
