Preparation and characterization of novel magnetic nanocomposite-bonded metalloporphyrins as biomimetic nanocatalysts

open access: yes, 2010
In this work, novel magnetic nanocomposite-bonded metalloporphyrins were synthesized by an effective silanation approach between 3-aminopropyltriethoxysilane derivatized metalloporphyrins and silica-coated magnetic Fe3O4 nanoparticles.

Targeting peroxynitrite production in a model of persistent temporomandibular disorder comorbid with migraine

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 21, Page 6371-6385, November 2026.
Background and Purpose The persistence of temporomandibular disorders (TMDs), particularly myogenous, in a person with migraine can lead to exacerbated clinical outcomes and limited response to treatment. The pro‐nociceptive reactive nitroxidative species, peroxynitrite, is involved in migraine mechanisms, but little is known of its role in this ...

Detection of phosphine derivates using metalloporphyrins [PDF]

open access: yes, 2015
Starting from the knowledge that phosphine derivatives exhibit medium/high toxicity, in this study we focused on the behavior of Co(II)- 5,10,15,20-tetratolyl-porphyrin (CoTTP) and Mn(III)-5,10,15,20-tetraphenyl-porphyrin chloride (MnTPPCl) as active UV ...

Novel catalysis by metalloporphyrins [PDF]

open access: yes, 2007
Metalloporphyrins have long been known to be effective catalysts for a variety of organic reactions. These include cyclopropanation, epoxidation, and aziridination of olefins.

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

open access: yesChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...

Use of Novel Cardanol-Porphyrin Hybrids and Their TiO2-Based Composites for the Photodegradation of 4-Nitrophenol in Water

open access: yesMolecules, 2011
Cardanol, a well known hazardous byproduct of the cashew industry, has been used as starting material for the synthesis of useful differently substituted “cardanol-based” porphyrins and their zinc(II), copper(II), cobalt(II) and Fe(III) complexes.

Synthesis and characterization of zeolite-encapsulated metalloporphyrins

open access: yes, 2015
Metalloporphyrins of Fe(III) and Cu(II) were prepared inside the large pores of the zeolite NaY by a process of sequential introduction of components followed by assembly inside the void space of the zeolite.

Efficient Sunlight Degradation of Wide‐Spectrum Antibiotics Through Enhanced Charge Separation in SnTCPP NPs‐Nb2C Schottky Heterojunction: Ultrafast Carrier Dynamic Study

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 19, 6 October 2026.
Due to enhanced charge transfer and carrier mobility on the surface, the SnTCPP NPs‐Nb2C Schottky heterojunctions demonstrate exceptional sunlight‐driven catalytic activity toward tetracycline antibiotics and ofloxacin degradation, achieving a removal efficiency of up to 99.9% within 60 min of irradiation, both in model wastewater and natural water ...
