Ammonia (NH3) is one of the important chemicals for human life. The demand ammonia expected to increase every year. Conventionally, fixation process N2 produce NH3 in industrial sector carried out through Haber−Bosch process, which requires extreme temperature and pressure conditions that consume a high amount energy emit considerable CO2. Therefore, it necessary develop alternative technology ...

Current industrial production of ammonia from the Haber-Bosch process and its transport concomitantly produces a large quantity CO2. Herein, we successfully synthesize inorganic-structure-based catalysts with [Fe-S2-Mo] motifs connecting structure similar to that FeMoco (a cofactor nitrogenase) by placing iron atoms on single molecular layer MoS2 at various loadings. This type new catalytic mat...

Despite the Haber-Bosch process being more than 100 years old, only incremental improvements have been achieved until recently. Now, by combining catalyst expertise of CLARIANT and engineering knowledge CASALE, a breakthrough has realized. AmoMax®-Casale is new ammonia synthesis jointly developed Casale Clariant particularly for use in converters. customized evolution well-known, wustite-based ...

Electrochemically converting nitrate ions back to valuable ammonia (NH3) represents a sustainable alternative the traditional Haber-Bosch process. However, NH3 electrosynthesis is currently restricted by low catalytic activities and Faradaic efficiency (FE) of NO3−-to-NH3. Here we report an interlayer-confined reduction reaction (NTRR) in two-dimensional layered structure. The results indicate ...

The shipping industry has reached a higher level of maturity in terms its knowledge and awareness decarbonization challenges. Carbon-free or carbon-neutralized green fuel, such as hydrogen, ammonia, methanol, are being widely discussed. However, little attention paid to the fuel pathway from renewable energy shipping. This paper, therefore, provides review production methods for power (green me...

Hydrogen production using renewable energy is regarded as a key technology to achieve sustainable society. But hydrogen has low volumetric density and it’s difficult storage transport. Therefore, ammonia normally produced by the Haber-Bosch process with nitrogen attracts much attention carrier. Although toxic, it risk because we can detect immediately due its characteristic smell when leaks. So...

Electrochemical nitrogen reduction reaction (NRR) to ammonia (NH3) driven by renewable electricity is a promising alternative the current energy-intensive and fossil feedstock-dependent Haber–Bosch (H–B) process. The intrinsic inertness of N2 molecule competition hydrogen evolution (HER) are primary challenges for NRR. Although transition metal-based electrocatalysts can solve kinetic limitatio...

Ammonia has been intensively studied as a clean, sustainable fuel source and an efficient energy storage medium due to its effectiveness hydrogen carrier molecule. However, the currently used Haber–Bosch process requires large fossil input, high temperatures pressures, well significant capital investment. These constraints prevent decentralized small-scale ammonia production at level of small f...

Abstract Selective and efficient ammonia (NH 3 ) production using an electrocatalytic nitrate reduction reaction (ECNtRR) under ambient conditions provides a green promising alternative to the traditional energy-intensive Haber–Bosch process. The challenge is in design controlled syntheses of electrocatalysts with high selectivities, NH yield rates (Y NH3 long-term stabilities. Here, freestandi...
