Asymmetric phthalocyanines conjugated on silica for the photocatalytic degradation of organic pollutants synthesis, characterization and investigation of the photophysicochemical properties

Aggregation Effect on Phthalocyanine Photocatalytic Degradation Efficiency Using Orange G and Methyl Orange as Test‐pollutant Compounds in Aqueous Medium

“…The difficulty faced in getting Pcs solubilized in aqueous media for environmental safety application is a familiar challenge, which has limited the number of research papers available under this subject. The few research papers that are available are a combination of works carried out in aqueous or non‐aqueous media [28–35] . The best results so far, to the best of our knowledge, are those reported by Mapukata et al .…”

“…The few research papers that are available are a combination of works carried out in aqueous or non-aqueous media. [28][29][30][31][32][33][34][35] The best results so far, to the best of our knowledge, are those reported by Mapukata et al where they employed two different Pcs: 2-[5-(phenoxy)-isophthalic acid] 9 (10), 16 (17), 23(24)-tris (tertbutyl)phthalocyaninato Zn(II) (M1) and 2, 10, 16, 24-tetra 5-(phenoxy)-isophthalic acid phthalocyaninato Zn(II) (M2), as photocatalysts embedded in polymer material for the photodegradation of MO and OG in aqueous media. [35] They found that the observed k obs were decreasing with increasing concentration of the pollutants (MO or OG).…”

Nanostructural catalyst: metallophthalocyanine and carbon nano-onion with enhanced visible-light photocatalytic activity towards organic pollutants

“…These connections provide unique properties, such as increased surface areas, long lifetimes, facile recovery and easy separation of the catalyst. Among these systems, polymers 56 and inorganic 57,58 and organic nanoparticles 59 have been studied. Synthetic efforts have also been devoted to implementing carbon nanostructures (CNs) into these macromolecular systems.…”
