Description N-doped mesoporous titania was synthesized by templating method. Three different types
of photocatalysts were synthesized by varying chitosan to titania compositions and
designated as N-doped mesoporous titania (1:1), (1:2) and (1:3). These synthesized photocatalysts
were characterized by XRD, BET-SA, UV-DRS, SEM-EDX and XPS. This photocatalyst
is active in visible range with band gap energy of 2.65 eV. Formation of TieN bond
reveals the decrease in the band gap of TiO2. The synthesized photocatalysts were
screened initially for their photocatalytic activity using water splitting reaction. The
maximum hydrogen yield of 2654.57 mmol/h/g of photocatalyst was obtained for N-doped
mesoporous titania (1:2). This yield is 16 times higher as compared to the bench mark
material Degussa P-25 (161 mmol/h/g of photocatalyst). The best performing photocatalyst
N-doped mesoporous titania (1:2) was investigated in detail to study the influence of
various operating parameters. Reuse and recycle study results in steady hydrogen yield of
9605.56 mmoles for 30 h.
