Special Issue Information

Dear Colleagues,

The preparation of electrocatalytic nanomaterials and their application represent an important area of academic and industrial research.

In particular, Molecules has witnessed explosive growth in articles on electrocatalysis using new nanomaterials and novel strategies for improving the performance of nanomaterials. Progress in controlled syntheses and characterization of nanomaterials has benefitted the field of electrocatalysis through better understanding of fundamental mechanisms and development of practical catalysts.

We invite authors to contribute original research articles or comprehensive review articles covering the most recent progress and new developments in the design, synthesis and characterization of electrocatalytic nanomaterials. All possible applications of electrocatalysis must be explored.

Dr. Zhiqiang Niu

Abstract
A sulfanyl porphyrazine derivative with peripheral phthalimide moieties was metallated with cobalt(II) and iron(II) metal ions. The purity of the macrocycles was confirmed by HPLC, and subsequently, compounds were characterized using various analytical methods (ES-TOF, MALDI-TOF, UV–VIS, and NMR spectroscopy).

A sulfanyl porphyrazine derivative with peripheral phthalimide moieties was metallated with cobalt(II) and iron(II) metal ions. The purity of the macrocycles was confirmed by HPLC, and subsequently, compounds were characterized using various analytical methods (ES-TOF, MALDI-TOF, UV–VIS, and NMR spectroscopy). To obtain hybrid electroactive electrode materials, novel porphyrazines were combined with multiwalled carbon nanotubes. The electrocatalytic effect derived from cobalt(II) and iron(II) cations was evaluated. As a result, a significant decrease in the overpotential was observed compared with that obtained with bare glassy carbon (GC) or glassy carbon electrode/carbon nanotubes (GC/MWCNTs), which allowed for sensitive determination of hydrogen peroxide in neutral conditions (pH 7.4). The prepared sensor enables a linear response to H2O2 concentrations of 1–90 µM. A low detection limit of 0.18 μM and a high sensitivity of 640 μA mM−1 cm−2 were obtained. These results indicate that the obtained sensors could potentially be applied in biomedical and environmental fields. Full article
