“…14 For several years, extensive efforts have been devoted to designing structural and functional models so as to mimic the protonation and redox properties of the H-cluster. [15][16][17][18][19][20][21][22][23][24] These models include a variety of dithiolato ligands, μ-(SCH2)2X, in which the central atom/group X could be NR, CR2, O, S, SnR2 or (Ph)P=O ( Figure 1B). [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] Moreover, several research groups have reported approaches for introducing strong σ-donor ligands, such as phosphines and phosphites, at the diiron core to enhance the protophilicity of the model complexes ( Figure 1B).…”

“…So, much concerns about the development of new and efficient hydrogen evolution catalysts based on the active site of [FeFe]-hydrogenase, resulting in a large number of models for the active site of [FeFe]-hydrogenase were designed and synthesized. [2][3][4][5] Crystallographic studies demonstrated that the [FeFe]-hydrogenase active site features a [4Fe4S] cluster and a [2Fe2S] cluster. The two clusters are linked by a cysteinyl residue and the [2Fe2S] cluster was considered as the catalytic site.…”

The chemistry of the diiron dithiolato hexacarbonyl complex Fe 2 (μ-edt)(CO) 6 (edt, 1,2-ethanedithiolate) has received special attention, largely because that its structure is similar with the active site of [FeFe]-hydrogenase. In order to enrich the chemistry of complex Fe 2 (μ-edt)(CO) 6 and synthesize new hydrogen evolution catalysts, a new route to the diiron dithiolato hexacarbonyl complex Fe 2 (μ-edt)(CO) 6 was described. Reaction of Fe 3 (CO) 12 and Me 3 SiSCH 2 CH 2 SSiMe 3 in the presence of Et 3 N at 80°C afforded Fe 2 (μ-edt)(CO) 6 in 90 % yield. Furthermore, reaction of Fe 2 (μ-edt)(CO) 6 and aminodiphosphine ligands (Ph 2 P) 2 NC 6 H 4 R (R =À 3-CCH, 4-CCH) produced the new PNP-chelated diiron dithiolato complexes Fe 2 (μ-edt)(CO) 4 {k 2-(Ph 2 P) 2 NC 6 H 4 R} (1 and 2). All the complexes were characterized by elemental analysis, IR, NMR spectroscopy, and particularly for 1 and 2 by X-ray single diffraction analysis. In addition, the electrochemical results indicated that 1 and 2 could be considered as electrocatalysts for hydrogen evolution reaction.

“…Unfortunately, enzyme based biosensors suffer denaturation of the enzyme and different efforts have been done to improve their stability. Inorganic compounds that mimic the electrocatalytic activity of enzymes have been extensively studied in recent years [3][4][5][6][7][8][9].…”

In this work, a new hydrogen peroxide (H2O2) electrochemical sensor was fabricated. Prussian blue (PB) was electrodeposited on a glassy carbon (GC) electrode modified with zirconia doped functionalized carbon nanotubes (ZrO2-fCNTs), (PB/ZrO2-fCNTs/GC). The morphology and structure of the nanostructured system were characterized by scanning and transmission electron microscopy (TEM), atomic force microscopy (AFM), specific surface area, X-ray diffraction (XRD), thermogravimetric analysis (TGA), Raman and Fourier transform infrared (FTIR) spectroscopy. The electrochemical properties were studied by cyclic voltammetry (CV) and chronoamperometry (CA). Zirconia nanocrystallites (6.6 ± 1.8 nm) with cubic crystal structure were directly synthesized on the fCNTs walls, obtaining a well dispersed distribution with a high surface area. The experimental results indicate that the ZrO2-fCNTs nanostructured system exhibits good electrochemical properties and could be tunable by enhancing the modification conditions and method of synthesis. The fabricated sensor could be used to efficiently detect H2O2, presenting a good linear relationship between the H2O2 concentration and the peak current, with quantification limit (LQ) of the 10.91 μmol·L−1 and detection limit (LD) of 3.5913 μmol·L−1.
