Enhanced photocatalytic capacity of ZnS–ZnO–Sm2O3 composites for the removal of dyes and antibiotics in visible light region

Sm2O3 and Sm2O3-based nanostructures for photocatalysis, sensors, CO conversion, and biological applications

“…Catalysis Science & Technology Perspective Interesting findings were observed in a report by Zheng et al in which the effect of binary and ternary composites on the photocatalytic degradation of TCH, rhodamine B (RhB), methyl orange and methylene blue was investigated. 88 The photocatalytic activities of ternary (ZnS-ZnO-Sm 2 O 3 ) and binary ZnO-Sm 2 O 3 were reported to be influenced by both ˙OH and ˙O2…”

“…88 with permission from Journal of Industrial and Engineering Chemistry, copyright 2023. 88 instance, Yan et al reported a novel electrode material used in enzyme-free electrochemical detection of H 2 O 2 using Sm 2 O 3 hydrangea microspheres. 41 The Sm 2 O 3 hydrangea microsphere electrode exhibited excellent performance which showed the following characteristics: detection linear range from 1 to 320 μM (R 2 = 0.997), ultrahigh sensitivity of 20.5 μA mM −1 , low detection limit of ∼1 μM, fast response at 3 s to attain 95% of the steady current as well as high stability.…”

“…A mixture of rounded and irregular particles was obtained and the composites were used for intermediated-temperature methanol fuel cells. ZnS–ZnO–Sm 2 O 3 composites were used for photocatalytic removal of dyes and antibiotics in the visible light region as reported by Zheng et al 88 ZnS–ZnO–Sm 2 O 3 composites were synthesized hydrothermally by mixing Sm(NO 3 ), Zn(NO 3 ) 2 and ZnS with urea PVP and ethanol. The reaction was heated at 180 °C for 1 h and the product was dried at 50 °C for 10 h. The final product was then calcined at 300 °C for 2 h producing 10 nm size spherical particles.…”
