Improved photocatalytic efficiency of titanium dioxide-hematite composite by air plasma

Effect of Different Amounts of Pt on Fe3O4−TiO2 for Photocatalytic H2 Production Under Solar Light

“…Besides, the weak peak at 530 eV was attributed to the defect oxygen vacancies (−OH) after the hydrogen production reaction [37] . The red shift of the peaks confirms the formation of substitution between TiO 2 and Fe due to the electronic interaction [52] . The decreasing intensity indicated a low oxygen vacancies/lattice oxygen ratio which means a low recombination rate [53] .…”

“…[37] The red shift of the peaks confirms the formation of substitution between TiO 2 and Fe due to the electronic interaction. [52] The decreasing intensity indicated a low oxygen vacancies/lattice oxygen ratio which means a low recombination rate. [53] The variation in the binding energy of Ti 2p 3/2 and O 1s showed the existence of TiÀ OÀ Pt bonds in FT sample.…”
