Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons. 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds. One of the most common occurrences of nitriles is in Nitrile rubber. Name: 4-Nitrophthalonitrile.
Wang, Shuai;Deng, Li-Hong;Du, Yi-Fei;Song, Xian-Liang research published 《 Graphene carbon black as catalyst support: The influences of iron phthalocyanine loading and carbon black additive amount on the power generation performance of direct glucose fuel cell》, the research content is summarized as follows. Fast accessibility of oxygen reduction reaction (ORR) species to a catalyst surface with the efficient utilization of every catalytic site plays a critical role in catalysis. Therefore, engineering of the structure and morphol. of catalyst supports to both anchor and expose catalytic sites at three-phase-boundaries, accelerating the mass transport of reaction-species through the active sites, can be regarded as one of the most prospective methods to promote the efficient utilization of every catalytic site, giving prominent cell performance. Herein, two series of oxygen reduction reaction catalysts are prepared: reduced graphene oxides (rGO) with different loading amounts of iron phthalocyanine TFePc/rGO-X (X = 1,2,3,4 and 5); and TFePc/rGO-3 that is intercalated by different amounts of carbon black TFePc/rGO/CB-Y (Y = 1,2,3,4 and 5). The catalytic activities and stabilities of these catalysts were evaluated by cyclic voltammetry and linear sweep voltammetry. As expected, the 3D rGO/CB/rGO network is demonstrated as a singular catalyst-loading platform, with interlayer spacing that could be elaborately tuned via a simple carbon black intercalation. This enables ORR-species to be efficiently transported to each catalytic site. Besides, the optimal catalyst of TFePc/rGO/CB-3 exhibits more pos. ORR peak potential than Pt/C catalyst. More significantly, in a practical cell, the cell performances were highly consistent with ORR active and the first-best cell performance of 0.86 mWcm-2 in power d. was achieved for TFePc/rGO/CB-3. This is mainly attributed to the synergistic effect of rGO and carbon black, as well as the π-π interaction between rGO and TFePc.
Name: 4-Nitrophthalonitrile, 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., 31643-49-9.
