“…The outlet gas was passed through a KOH solution (20%) at different times. Concentration of product mercaptan was determined at 30-min intervals using EM potentiometer (AT-500) and UOP 163 method [15,16].…”

“…Moreover, a GO support leads to emergence of active sites on the catalyst which in turn lead to greater surface area between the gas flow on one hand and the nanocatalyst on the other. As a result, mercaptan conversion becomes greater in the outlet stream [15,16]. Figure 5a shows the effect of temperature on the removal of mercaptan in the range of 50-100 °C and a fixed amount of GHSV (1000 h −1 ).…”

“…In the previous studies, carbon nanotubes (CNTs) were considered as supports for porphyrin derivatives. As high conversion of mercaptan was achieved using 10% cobalt phthalocyanine/MWCNT and 20% w (Fe) TCPP-MWCNT in the variant operating condition, we developed this method for GO as a support [15,16]. In this paper, we intend to use another derivative of nanocarbon structure like GO as a support for porphyrin complex.…”

The present study reports an eco-friendly, biosynthesis of silver nanoparticles (AgNPs) using stem bark extract of Diospyros montana. Initially, the synthesis of AgNPs was confirmed by visual observation as color change. Further, the morphology of the biosynthesized nanoparticles, average size and presence of elemental silver were characterized by UV-Visible spectroscopy, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray and dynamic light scattering spectrometer. Qualitative phytochemical screening and FTIR spectral peaks supported the role of phytochemicals in bark extract for the metal reduction, stabilization and capping of silver nanoparticles. XRD studies demonstrated that crystalline nature and their average size of nanoparticles was 28 nm as determined by Scherrer's formula. The antioxidant ability of AgNPs and plant extract was analyzed using DPPH and Hydrogen peroxide assay. The percentage of DPPH and H 2 O 2 activity was increased with increasing concentration of AgNPs. In vitro antibacterial effect of various concentration of AgNPs was investigated against both Gram positive (B.subtilis and S.aureus) and Gram negative (E.coli and K.aerogenes) bacterial strains. The result shows that biosynthesized AgNPs have significant antibacterial activity.

“…One way to solve this problem and hence increase the efficiency of catalyst is immobilization of metal phthalocyaninates onto surface of organic polymers of carbon nanotubes. [99][100][101] Key role upon copolymerization and immobilization on a surface is taken by anchor group's formation. In this way, functional group being part of phthalocyanine able easily to form radical or ion becomes mandatory for successful immobilization.…”

The work reports catalytic properties of series of cobalt phthalocyanines peripherally substituted with consistently changing sulfonated fragments. Data on heterogenization of cobalt phthalocyaninates onto organic and inorganic polymers are provided. Comparing catalytic activity of the macrocycles in dependence on structure and peripheral substituent as well as polymer carrier's type is given. Application of cobalt phthalocyanine's sulfonic acids for fine synthesis of thiuram E upon both homogeneous and heterogeneous catalysis is shown to be prospective.

“…Catalysts obtained by immobilization of metallophthalocyanines on solid-phase carriers, carbon nanotubes, organic polymers are also perspective [8][9][10]. Carbon residues of phthalocyanine molecule may be used as anchoring groups for linking with biological molecules containing fragments of primary amines [11], immobilization on polymer surface, for example silica [12] or nanotubes [13] that may be used to create novel materials for purposes mentioned above.…”

Difunctional and symmetric phthalonitriles were synthesized by nucleophilic substitution of brome and nitro-group in 4-bromo-5-nitro-phthalonitrile for residues 4-amino-, 4-hydroxyl-and 4-sulfanyl benzoic acid. Symmetrical and difunctional substituted cobalt phthalocyanines were obtained by template synthesis based on mentioned phthalonitriles. Their spectral properties and catalytic activity in aerobic oxidation of sodium N,N-carbomoditiolate were investigated.
