“…As the potential was scanned positively, the anodic current increased in two steps until it reached a peak current value: the pre-wave region between 0 and 0.4 V and the exponential growth region after 0.4 V. This is because there are two major hydrazine species, hydrazinium [N 2 H 5 ] + and hydrazinediium [N 2 H 6 ] 2 + , in the solution. [22,23] The i-V response was initially smooth and continuous, suggesting no bubble formation in this range. [24] Then the current suddenly dropped to a residual current value, corresponding to the generation of a single bubble that actively blocked the Pt nanoelectrode.…”

Regulating the dissolved‐gas concentration at the electrode‐solution interface represents a promising universal strategy to achieve high efficiency towards gas evolution reactions. Here, we present a facile method to modulate the interfacial dissolved‐gas concentration using cationic fluorinated pyridinium sulfonate (CFPS) for highly efficient hydrazine oxidation (HzOR). We found that the interfacial dissolved‐nitrogen concentration was effectively lowered by the cationic surfactant CFPS, while CFPS still ensured a sufficient exposure of the active sites during the HzOR. As a result, relative to pure Pt, the CFPS‐modulated Pt exhibited a 2.1‐fold higher current density and a lower overpotential for HzOR. This work presents a new avenue to achieve highly efficient hydrazine oxidation through regulating the interfacial gas concentration.

Catalytic Organometallic Reactions of Ammonia

Until recently, ammonia had rarely succumbed to catalytic transformations with homogeneous catalysts, and the development of such reactions that are selective for the formation of single products under mild conditions has encountered numerous challenges. However, recently developed catalysts have allowed several classes of reactions to create products with nitrogen-containing functional groups from ammonia. These reactions include hydroaminomethylation, reductive amination, alkylation, allylic substitution, hydroamination, and cross-coupling. This Minireview describes examples of these processes and the factors that control catalyst activity and selectivity.

“…As presented in TGA curve exhibited weight loss amount, which is almost 30% at 550°C. According to the literature, important part of this weight loss, especially in temperatures more than 300°C, is due to the loss of N 2 from azine section, triazole ring decomposition, and maybe single bond tearing. But about ferrocene scaffold, it is noteworthy that it is one of the first organometallic compounds that remain intact up to 500°C .…”

Poly(azine ferrocene‐triazole‐xanthone amide) (PAFTXA) was successfully synthesized from azine ferrocene bisacetylene (AFcB) and 2,7‐(N‐2‐azidoacetamide) xanthone (NAzX) by using click chemistry protocol. In this paper, innovative AFcB moiety incorporated in this procedure as a monomer. This monomer was prepared in three steps from ferrocene scaffold, and the synthetic processes were discussed in details. Characterization of the synthesized novel intermediate materials, monomer, and the resulting polymer was performed by nuclear magnetic resonance, Fourier transform infrared, thermal gravimetric analysis, differential scanning calorimetry, and ultraviolet‐visible spectrophotometer. In addition, the in vitro antibacterial activity of the polymer was appraised against Gram‐positive and Gram‐negative bacteria by using minimum inhibitory concentration method. Moreover; antitumoral effects of synthesized polymer were evaluated on Hela, MCF‐7, and Saos cancer cell lines and compared with normal fibroblast cell line by means of 3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyltetrazolium bromide assay. Promising antiproliferative effects were detected on both epitheloid and mesenchymal cancer cell lines depending on PAFTXA concentration and time. Survey on its characteristic features revealed the proficiencies of our prepared biomaterial such as its high thermal stability as well as valuable antitumoral and antibacterial capabilities that make it an appreciable candidate for further bioapplications.
