Enhanced photocatalytic discoloration of acid fuchsine wastewater by TiO2/schorl composite catalyst

Synergic Effect between Adsorption and Photocatalysis of Metal-Free g-C3N4 Derived from Different Precursors

“…Moreover, it should be noted that, at the same condition of temperature, g-C 3 N 4 sample derived from melamine exhibits sharper XRD peaks than that from dicyandiamide, implying that the former has better crystallinity with less defects and disturbances in the graphitic structure. According to XRD results, the crystal size of g-C 3 N 4 was computed by Scherrer formula D = Kλ / β cos θ , where D is the crystallite size (nm), K the Scherrer constant (about 0.9), λ the wavelength of Cu-K α radiation (0.15418nm), and β the full width of (002) diffraction peak at half maximum [ 43 ]. The calculated crystallite sizes of all g-C 3 N 4 samples are listed in Table 1 .…”

Structure-tunable hydrothermal synthesis of composite TiO2@glucose carbon microspheres (TiO2@GCs) with enhanced performance in the photocatalytic removal of acid fuchsin (AF)

“…The pseudo-first-order reaction kinetics can be used to describe the AF degradation rate in the heterogeneous photocatalytic oxidation process: 45…”

Synthesis and evaluation of a novel inorganic–organic composite flocculant, consisting of chitosan and poly‐ferric cerium silicate

“…[1][2][3][4] Conventional methods such as coagulation/ flocculation, membrane processes, adsorption, photocatalytic degradation, micro-electrolysis, and biological methods have been performed to remove pollutants from dye wastewater. [5][6][7][8][9] Among these techniques, coagulation/flocculation, as one of the most practiced technologies, is still widely used in the treatment of dye wastewater because of the low cost, high efficiency, short process and convenient operation. 10,11 However, with the increase of pollutants in water and in recent years the higher requirement for environment protection, traditional flocculants such as polyferric chloride (PFC), polyferric sulfate (PFS) and polyaluminum chloride (PAC) have found it difficult to meet the processing requirements.…”
