Ag 2 O and Fe 2 O 3 modified oxides on the photocatalytic treatment of pulp and paper wastewater

Enhanced photocatalytic activity of ZnO–NiO nanocomposites synthesized through a facile sonochemical route

“…This technique is complementary to the conventional approaches of waste water treatment such as filtration and sedimentation [1]. Wide band-gap semiconductors such as TiO 2 , ZnO, SnO 2 , WO 3 , Fe 2 O 3 , CdS and NiO are some of the most actively investigated systems as photocatalysts for water purification [2][3][4][5][6][7][8][9][10][11].…”

Facile fabrication of hierarchical p-Ag2O/n-Nb2O5 heterojunction microspheres with enhanced visible-light photocatalytic activity

“…In addition, according to the literature, the E VB and E CB of Ag 2 O were 1.44 eV and 0.14 eV, respectively. 17…”

Facile fabrication of Fe-doped Nb2O5 nanofibers by an electrospinning process and their application in photocatalysis

“…7,8 In this regard, many promising methods including metal and nonmetal doping, noble metal deposition or compositing with other semiconductor have been developed to improve the efficiency of Nb 2 O 5 as a photocatalytic material. [9][10][11][12][13][14][15] It has been proved that metal element doping was one of the most effective approaches to extend the spectral response of the wide-bandgap semiconductor to visible-light region. [16][17][18] Recently, some metal elements such as W, Mo, Fe, Cu and Mn have been employed to tune the electronic structure and enhanced the photocatalytic activity of the semiconductor photocatalysts.…”
