Enhanced visible light photocatalytic activity by up-conversion phosphors modified N-doped TiO2

N–TiO2 Photocatalysts: A Review of Their Characteristics and Capacity for Emerging Contaminants Removal

“…Therefore, considering the recovery of the catalyst, in the literature, studies can be found that are related to the immobilization of doped TiO 2 on suitable supports or even TiO 2 nanostructures, such as nanotubes arrays supported on titanium foils [106][107][108][109]. The immobilization of doped TiO 2 can occur in different types of substrates such as hollow glass spheres [110], reactor walls [111], membrane reactors [112], synthetic polymers [55,113,114], and graphene [79]. The most used methods for supporting titanium dioxide particles on a suitable substrate is dip coating (or the sol-gel method) [115], chemical vapor deposition [116], the hydrothermal method [117], and the solvent-casting method [55].…”

Activation of peroxymonosulfate by graphitic carbon nitride loaded on activated carbon for organic pollutants degradation

“…Advanced oxidation processes (AOPs) such as Fenton and Fenton-like technology, catalytic ozone oxidation and photocatalysis, have attracted extensive attention as the most efficient methods for the target organic pollutants decomposition [1][2][3][4][5][6]. Similar to these technologies, the method based on sulfate radicals (SO4 •− ) is a recently emerged AOP [7].…”

Synthesis of AgBr@Bi2O3 composite with enhanced photocatalytic performance under visible light

“…Thus developing visible-light responsive and high-efficiency photocatalysts consequently has become an imperative topic in photocatalysis field. Current researches mainly focus on the modification of photocatalyst (doping, coupling, and sensitization) and exploiting of new-typed promising photocatalysts [3][4][5][6]. Particularly, heterostructured photocatalyst has attracted wide attention owing to its superior photocatalytic performance to single-phase photocatalyst.…”
