Oxidation of Pollutants Catalyzed by Metallophthalocyanines

Voltammetric characterisation of the self-assembled monolayers (SAMs) of benzyl- and dodecyl-mercapto tetra substituted metallophthalocyanines complexes

“…For SAM 1 , SAM 6 and SAM 18 (subscripts represent hours of SAM formation, Fig. 2), it can be said that there is no blockage of Co +2 hence no significant decrease in both anodic and cathodic currents compared to that of the bare gold electrode and also no significant shift in the peak potentials while for SAM 24 and SAM 48 there were decrease in both anodic and cathodic peak currents and also increase in the peak separation (ΔE).…”

“…Their applications in their early discovery was mainly as dyes but over the years, there have been many applications in areas such as, photovoltaic devices [1] and [2], molecular electronics [3], catalysis [4], [5], [6] and [7] and sensing [8].…”

The Self‐Ordering Properties of Novel Phthalocyanines with Out‐of‐Plane Alkyl Substituents

“…By placing long alkyl (Pc series 1) [11,12] or alkoxy (Pc series 2) [11,13] side chains on the peripheral positions (2,3,9,10,16,17,23,24) of the phthalocyanine ring the solubility is enhanced and leads to liquid-crystalline behaviour in which the aromatic rings assemble into columnar stacks. Derivatives with long alkyl side chains attached to the nonpe-A C H T U N G T R E N N U N G ripheral sites (1,4,8,11,15,18,22,25) also form columnar liquid crystals (Pc series 3).…”

Dechlorination and destruction of 2,4,6-trichlorophenol and pentachlorophenol using hydrogen peroxide as the oxidant catalyzed by molybdate ions under basic condition

“…2,6-Dichloro-1,4-benzonquinone (DCQ), as a stable oxidation product of TCP in the porphyrins or peroxidase catalytic system (Meunier and Sorokin, 1997), was not detected at the end of the catalytic reaction. The chloride ion release data and the absence of DCQ at the end of reaction suggested the aromatic ring was destroyed in the degradation of TCP and PCP.…”
