Microwave synthesis of a novel magnetic imprinted TiO2 photocatalyst with excellent transparency for selective photodegradation of enrofloxacin hydrochloride residues solution

Fabrication of conductive and high-dispersed Ppy@Ag/g-C3N4 composite photocatalysts for removing various pollutants in water

“…It is known that the performance of the photocatalyst is related to the electron-hole pair separation efficient [45,46]. PL emission is a widely accepted technology to investigate the separation efficiency of electrons-holes in semiconductors [47].…”

Synthesis of magnetically separable Fe3O4@PANI/TiO2 photocatalyst with fast charge migration for photodegradation of EDTA under visible-light irradiation

“…Anatase TiO 2 exhibits superior photoactivity under UV light irradiation and is the most frequently used photocatalyst in water treatment process [15][16][17][18][19], but its wide band gap (3.2 eV) has obviously hindered its sufficient utilization of sunlight [20]. Therefore, some composite photocatalysts about anatase TiO 2 with visible-light response had been reported by many researchers in recent years [21][22][23][24][25][26][27][28][29][30]. For instance, Zhao et al synthesized a BiOBr-TiO 2 -graphene composite by using graphene as a nano-filler [31].…”

A mild synthetic route to Fe3O4@TiO2-Au composites: preparation, characterization and photocatalytic activity

“…To the best our knowledge, magnetic TiO 2 photocatalysts are primarily prepared using sol-gel method by directly coating Fe 3 O 4 particles with TiO 2 [9][10][11][12][13][14][15][16][17][18] or indirectly coating Fe 3 O 4 with a SiO 2 interlayer between Fe 3 O 4 and TiO 2 [18][19][20][21][22]. Unfortunately, the coated TiO 2 in these studies is nearly all amorphous, and amorphous TiO 2 is inactive as a photocatalyst under UV irradiation [23][24][25].…”
