Keywords: | SiO2; CdS; TPP; TPAPP; Sunlight; RR 120 | Issue Date: | 2020 | Project: | SFRH/BPD/86971/2012 | Serial title, monograph or event: | Journal of Molecular Structure | Volume: | 1210 | Abstract: | Initially, sphere shaped SiO2 was explored by adopting simple sol-gel method without any template. Later, the sphere like SiO2 was modified with cadmium sulfide (CdS) semiconductor and porphyrins. The formation of composites (CdS/SiO2-porphyrins) brought out by diverse characterization techniques that include XRD, Raman, FT-IR, FE-SEM, EDS, DRS and PL measurements. The photocatalytic activity of CdS/SiO2 was slightly influenced by porphyrins such as meso-tetra-phenyl-porphyrin (TPP) and 5,10,15,20-meso-tetra-(para-amino)-phenyl-porphyrin (TPAPP). The mechanism which has been proposed for Reactive Red 120 (RR 120) degradation by CdS/SiO2- porphyrins under sunlight. | URI: | https://hdl.handle.net/10316/90914 | ISSN: | 00222860 | DOI: | 10.1016/j.molstruc.2020.128021 | Rights: | openAccess |
