Visible-Light Driven Photocatalytic Degradation of Eosin Yellow (EY) Dye Based on NiO-WO₃ Nanoparticles

Tungsten-Based Catalysts for Environmental Applications

“…Well-crystalline NiO-WO 3 nanoparticles were synthesized by Rosaline et al [417] for the photocatalytic degradation of eosin yellow (EY) dye. A photocatalytic degradation rate of 95% was obtained after 180 min under visible-light irradiation.…”

Impact of Titanium Dioxide (TiO2) Modification on Its Application to Pollution Treatment—A Review

“…The core of photocatalytic technology is the photocatalyst, and many materials can act as a photocatalyst [5]. Table 1 shows the published data of different photocatalysts, including TiO 2 [6][7][8], SrTiO 3 [9][10][11], ZnO [12][13][14], WO 3 [15][16][17], ZrO 2 [18][19][20], and g-C 3 N 4 [21][22][23], and their performance. Among these photocatalysts, TiO 2 occupies an important position due to its stable 2 of 32 physical and chemical properties, strong oxidation capacity, high photocatalytic activity, and excellent biocompatibility [24][25][26].…”

“…Composites are also beneficial toward the stabilization of nanoparticles against phenomena such as sintering or aggregation [34].

Generating oxygen vacancies in Cu 2+ ‐doped TiO 2 hollow spheres for enhanced photocatalytic activity and antimicrobial activity

“…Introduction: Photocatalytic degradation of pollutants using solar energy is a green and sustainable strategy to solve energy crisis and environmental problems [1][2][3]. Over the past decades, inorganic semiconductor materials have been extensively investigated for photocatalytic degradation of pollutants [4][5][6]. Specifically, TiO 2 was found to be the most efficient and low-cost inorganic semiconductor photocatalysts due to its high chemical stability, outstanding mechanical, catalytic, and optical properties [7][8][9].…”
