Hadimane, Sowmyashree;Aralekallu, Shambhulinga;CP, Keshavananda Prabhu;Hojamberdiev, Mirabbos;Sannegowda, Lokesh Koodlur research published 《 Bioinspired Precious-Metal-Free N4 Macrocycle as an Electrocatalyst for the Hydrogen Evolution Reaction》, the research content is summarized as follows. The design and development of strategies and catalysts are essential for sustainable energy production, particularly for the hydrogen evolution reaction (HER). Precious Pt/C catalyst is known to demonstrate high efficiency in the electrochem. HER and suffers from commercialization issues. Therefore, precious-metal-free and organic-based catalysts are of importance for a future perspective. In this work, cobalt tetra[4-[2-(1H-benzimidazol-2-yl)phenoxy]]phthalocyanine (CoTBImPc) is synthesized for the first time and characterized by physicochem. and electrochem. techniques. 1H NMR and mass spectral data reveal the successful formation of the ligand and complex, whereas the thermogravimetry (TG) study confirms the thermal stability of the complex up to 400 °C. The electroactivity of CoTBImPc is compared with the hybrid composite of a carbon nanotube (CNT-CoTBImPc) and benchmark Pt/C catalyst for the HER. Linear sweep voltammetry (LSV) shows that an onset potential for the HER for CoTBImPc-CNT/GCE is shifted to a higher potential than that of CoTBImPc/GCE, suggesting that the HER is more feasible at the surface of CoTBImPc-CNT. Higher activity for CoTBImPc-CNT/GCE in comparison with that of CoTBImPc/GCE in 0.5 M H2SO4 (pH = 0.3) may be ascribed to the enhanced conductivity, a greater number of active sites, and a larger surface area. The hybrid composite yields a c.d. of -10 mA·cm-2 and demonstrates HER activity at a lower overpotential (63 mV). The benchmark Pt/C catalyst and the as-synthesized pristine phthalocyanine mol. exhibit the HER at overpotentials of 3 and 160 mV, resp., at a c.d. of -10 mA·cm-2. A lower Tafel slope value of 43.2 mV·dec-1 and a higher double-layer capacitance value of 44 mF·cm-2 confirm that the hybrid composite is one of the superior catalyst candidates for the HER compared to the bare glassy carbon electrode (GCE) and pristine metal phthalocyanine. Further, CoTBImPc-CNT/GCE also exhibits an excellent stability during the HER.
31643-49-9, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., Recommanded Product: 4-Nitrophthalonitrile
