Synthesis of ammonia directly from air and water at ambient temperature and pressure
The N≡N bond (225 kcal mol⁻¹) in dinitrogen is one of the strongest bonds in chemistry therefore artificial synthesis of ammonia under mild conditions is a significant challenge. Based on current knowledge, only bacteria and some plants can synthesise ammonia from air and water at ambient temperature and pressure. Here, for the first time, we report artificial ammonia synthesis bypassing N₂ sep...
متن کاملSynthesis of ammonia directly from wet air using Sm(0.6)Ba(0.4)Fe(0.8)Cu(0.2)O(3-δ) as the catalyst.
Ammonia was directly synthesised from wet air at 400 °C at atmospheric pressure. A new perovskite Sm(0.6)Ba(0.4)Fe(0.8)Cu(0.2)O(3-δ) was used as the electrocatalyst for electrochemical synthesis of ammonia. Ammonia formation rates of 9.19 × 10(-7) mol s(-1) m(-2) and 1.53 × 10(-6) mol s(-1) m(-2) were obtained at 400 °C when wet air and wet N2 were introduced into a simple single chamber reacto...

کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولremoval of ammonia from air, using three iranian natural zeolites
ammonia in air can be hazardous to human and animal life and should be removed from the environment. recently the removal of environmental pollutants such as ammonia by means of natural and modified zeolites has attracted a lot of attention and interests. in this study the capability of three iranian natural zeolites (clinoptilolite) in point of view of removal of ammonia from air was investiga...
متن کاملSynthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...
