The incorporation of the MWCNTs on the surface of the TiO2 film (MOCPc–MWCNT systems) gave higher photocurrent density than the bare MOCPc complexes. Also, from the EIS results, the MOCPc–MWCNT hybrids gave faster charge transport kinetics (approximately three times faster) compared to the bare MOCPc complexes. The electron lifetime was slightly longer (ca. 6 ms) at the ZnOCPc systems than at the (OH)2SiOCPc system (ca. 4 ms) meaning that the presence of the MWCNTs on the surface of the TiO2 film did not show any significant improvement on preventing charge recombination process.]]> Tue 18 Jul 2023 21:24:00 SAST ]]> Self-assembled monolayers (SAMs) of cobalt tetracarboxylic acidchloride phthalocyanine covalently attached onto a preformed mercaptoethanol SAM https://commons.ru.ac.za/vital/access/manager/Repository/vital:55989 Tue 06 Sep 2022 13:36:01 SAST ]]> Novel amperometric glucose biosensor based on an ether-linked cobalt(II) phthalocyaninecobalt(II) tetraphenylporphyrin pentamer as a redox mediator https://commons.ru.ac.za/vital/access/manager/Repository/vital:6583 Thu 13 May 2021 07:16:44 SAST ]]> Preferential electrosorption of cobalt (II) tetra-aminophthalocyanine at single-wall carbon nanotubes immobilized on a basal plane pyrolytic graphite electrode https://commons.ru.ac.za/vital/access/manager/Repository/vital:6584 Thu 13 May 2021 05:08:50 SAST ]]> Electropolymerizable iron (III) and cobalt (II) dicyanophenoxy tetraphenylporphyrin complexes https://commons.ru.ac.za/vital/access/manager/Repository/vital:56236 Thu 08 Sep 2022 21:56:50 SAST ]]> Electrocatalytic oxidation and detection of hydrazine at gold electrode modified with iron phthalocyanine complex linked to mercaptopyridine self-assembled monolayer https://commons.ru.ac.za/vital/access/manager/Repository/vital:56235 Thu 08 Sep 2022 21:54:21 SAST ]]> Comparative electrochemistry and electrocatalytic activities of cobalt, iron and manganese phthalocyanine complexes axially co-ordinated to mercaptopyridine self-assembled monolayer at gold electrodes https://commons.ru.ac.za/vital/access/manager/Repository/vital:56234 MnPc > CoPc. This finding is remarkable as it suggests that the success of using this method of self-assembling of MPc onto gold electrode is largely dependent on the bond distance between the pyridine linker and the central metal of the MPc; the shorter the distance, the faster the co-ordination and the better the electrocatalytic properties towards L-cysteine and thiocyanate. Thus, the superiority of FePc-based SAM over those of the MnPc and CoPc, has been proposed to be the result of the more favorable axial co-ordination properties of FePc with pyridine (i.e. shorter Fe–N(pyridine) bond length.]]> Thu 08 Sep 2022 21:51:41 SAST ]]> Comparative efficiency of immobilized non-transition metal phthalocyanine photosensitizers for the visible light transformation of chlorophenols https://commons.ru.ac.za/vital/access/manager/Repository/vital:56233 SiPcSmix > SnPcSmix > ZnPcSmix > GePcSmix > ZnPcS4 > AlPcSmix > AlOCPc > AlPcS4. The generation of singlet oxygen (1O2) by these immobilized MPc photosensitizers was found to play a major role in their photoactivities towards the transformation of these chlorophenols. Langmuir–Hinshelwood (L–H) kinetic model studies showed that the ZnOCPc, GePcSmix and ZnPcSmix photocatalysis occurred on the catalysts surface. © 2005 Elsevier B.V.
