Sustainable nitrogen fixation with nanosecond pulsed spark discharges: insights into free-radical-chain reactions

Shuai Zhang et al.

Summary: A nanosecond pulsed spark discharge technique was developed for sustainable nitrogen fixation. Through experiments and modeling, it was found that chain reactions between O and N radicals and vibrationally excited N-2 and O-2 molecules are the key pathways for NOx formation. These findings provide new insights into sustainable and decentralized NOx production.

Effect of texture and physical properties of catalysts on ammonia synthesis

Rahat Javaid et al.

Summary: This study reports highly efficient mixed oxide supported Ru catalysts for ammonia synthesis at mild reaction conditions. By using different Mg and Ce contents in the MgO-CeO2 supports and loading 1% Ru, efficient ammonia synthesis was achieved. Even with higher MgO content, the mixed oxide MgO-CeO2 supported catalysts exhibited comparable ammonia synthesis yields to pure CeO2 supported catalysts, indicating that the catalytic activity is highly dependent on the texture and physical properties of the catalysts. The presence of highly dispersed Ce and Ru is suggested as the reason for the higher yield of ammonia obtained from Ru/MgO-CeO2 catalysts with selective deposition of Ru on CeO2.

Shielding Protection by Mesoporous Catalysts for Improving Plasma-Catalytic Ambient Ammonia Synthesis

Yaolin Wang et al.

Summary: Plasma catalysis holds promise for decentralized NH3 synthesis using renewable energy, with a bespoke design of supported Ni catalysts showing potential for efficient NH3 production. By depositing Ni active sites on the surface of mesoporous MCM-41, it enhances plasma-catalyst interactions and shields NH3 from decomposition, driving the reaction forward effectively. This demonstrates the importance of rational catalyst design for improving plasma-catalytic processes.

Mechanochemical Synthesis of RuCo/MgTiO3 Catalysts for Nonthermal Plasma-Assisted Ammonia Synthesis

Yuxin Zhang et al.

Summary: The development of robust catalysts is essential for nonthermal plasma-assisted ammonia synthesis. In this study, a mechanochemical synthesis method was used to prepare a bimetallic RuCo/MgTiO3 catalyst for NTP-assisted NH3 synthesis. The physicochemical properties of the catalyst were systematically investigated, and it exhibited high NH3 synthesis rate and energy efficiency. However, the energy barrier approach may not be suitable for studying the dynamics of the NTP-catalytic system.

Microwave-assisted ammonia synthesis over Ru/MgO catalysts at ambient pressure

Christina Wildfire et al.

Summary: In this study, microwave synthesis of ammonia over Ru/MgO catalysts was conducted at 320℃ under ambient pressure with different Ru loading levels. Higher Ru loading showed better dispersion, leading to decreased sintering and enhanced activity and stability. The microwave reactor also offered faster catalyst recovery compared to traditional thermal convectional Haber Bosch (HB) technology.

Formation of Catalytic Active Sites in Hydrothermally Obtained Binary Ceria-Iron Oxides: Composition and Preparation Effects

Tanya Tsoncheva et al.

Summary: A series of mesoporous cerium-iron binary oxides were prepared using CTAB as a template via a hydrothermal technique. The influence of Fe/Ce ratio and variations in preparation techniques on the properties of the materials were studied extensively. The shared Ce-O-Fe structures played a key role in the catalytic behavior, which could be controlled by the Fe/Ce ratio and the hydrothermal synthesis procedure.

Enhanced Ammonia Synthesis Activity of Ceria-Supported Ruthenium Catalysts Induced by CO Activation

Bingyu Lin et al.

Summary: Metal-support interactions strongly impact the catalytic performances of ceria-supported metal catalysts, and hydrogen treatment at high temperature is essential for the preparation of catalysts with strong metal-support interaction (SMSI). CO activation of a Ru/CeO2 catalyst enhances the reduction degree and exposure of Ru species, leading to the formation of electron-enriched Ru delta- species and Ru delta-OV-Ce3+ sites, resulting in high ammonia synthesis activity and alleviating the ill effect of hydrogen poisoning. These findings are crucial for designing supported metal catalysts with metallic species as active sites.

Plasma Catalysis for Ammonia Synthesis: A Microkinetic Modeling Study on the Contributions of Eley-Rideal Reactions

Yannick Engelmann et al.

Summary: The study uses microkinetic models to investigate the impact of different plasma conditions and transition metal catalysts on the NH3 synthesis process. Vibrational distribution functions, radical reactions, and transition metal types all affect the NH3 turnover frequencies (TOFs). The results show that the NH3 TOFs vary depending on the population of vibrational levels of N-2, and at higher concentrations of plasma-generated radicals, the dependence on catalyst material decreases.
