Cd²⁺Counterion-Assisted Synthesis of Uniform CdS Nanospheres Capped with the Anionic Surfactant Sodium dodecylsulfate

Fast photodegradation of antibiotics and dyes by an anionic surfactant-aided CdS/ZnO nanodispersion

“…43 The stretching vibration of SO (1112 cm −1 ) indicates the presence of SDS on the surface of the catalyst. 44 The blue shift of the 1621 cm −1 peak was found in CSZ, indicating that CdS compounds with ZnO form a composite. 28…”

“…43 The stretching vibration of SQO (1112 cm À1 ) indicates the presence of SDS on the surface of the catalyst. 44 The blue shift of the 1621 cm À1 peak was found in CSZ, indicating that CdS compounds with ZnO form a composite. 28 UV-vis DRS was used to analyse the optical properties of the materials and calculate the energy band value of CSZ.…”

Ferromagnetic behavior of Cd1−xNixS nanorods: a novel study

“…The PL spectrum shows the defect free nature of the synthesized nanorods because of its non-complex nature. In case of undoped CdS nanorods, the small hump in this spectra at 429 nm is due to blue emission [26]. The highest intensity peak at 530 nm may be because of the near band edge transitions, which are due to the [27].…”

Green Synthesis of Surfactant Capped CTAB@Ag Nanoparticles and Study of Its Catalytic Activity

“…The strong bands observed at 3256 cm −1 and 3276 cm −1 are due to presence of -OH stretching vibration in both bare Ag and CTAB@Ag nanoparticles, respectively. The medium intensity stretching bands observed at 2924 cm −1 in bare Ag and 2918 cm −1 , 2843 cm −1 in case of CTAB@Ag nanoparticles is due to presence of -CH stretching band of hydrocarbon [37]. The strong bands observed at 1631 cm −1 and 1624 cm −1 in bare Ag and CTAB@Ag nanoparticles respectively suggests the presence of stretching vibration of -C=C (alkene) [38].…”

“…Strong and medium intensity bands are observed in bare Ag and CTAB@Ag at 1444-1473 cm −1 , 1348-1361 cm −1 , 1152-1183 cm −1 attributed due to presence of methyl group, ether, alcohol. Some others bands at 996-1017 cm −1 , 754-760 cm −1 and 567-608 cm −1 are signi cant indicators of heterocyclic chemicals such as avonoids and alkaloids, which are active components of Z. o cinale and serve as a capping agent [35,37,38].…”
