摘要: Abstract Sol–gel synthesised TiO2 developed by our group was modified through the addition of nickel nitrate and ammonium carbonate in synthesis process. Photocatalysts were with different Ni/Ti molar ratios (0.015, 0.030, 0.045) constant Ni/N ratio equal to 1.5 subjected post-calcination at temperatures between 400 °C 700 °C. Characterisation carried out with: X-ray diffraction (XRD), UV–vis diffusive reflectance spectroscopy (DRS), photoelectron (XPS), transmission electron microscopy-energy dispersive analysis (TEM-EDX), thermal (TGA, DTA), aggregate size distribution, Fourier transform infrared (FTIR) nitrogen adsorption-desorption isotherm (BET). Photoactivity terms photocatalytic hydrogen production tested using a suspension photocatalyst 25 vol.% methanol. With continuous flow N2 headspace produced conducted gas chromatograph for quantification. No evidence presence N found photocatalyst. However, Ni enhanced photoactivity, calcination temperature 550 °C resulting highest photoactivity value 260.76 μmol h−1.
