Specifications

Gaseous N₂O₅ yield

{'zh': '1867', 'en': '1867'} ppm

Liquid-phase NOₓ⁻ concentration

{'zh': '3.2', 'en': '3.2'} mM

Energy consumption

{'zh': '3.95', 'en': '3.95'} MJ/mol

Advantages

Low energy consumption

The energy consumption for synthesizing high-concentration NOₓ is only 3.95 MJ/mol, significantly lower than conventional plasma nitrogen fixation processes, helping to reduce operating costs.

High yield

The gaseous N₂O₅ yield reaches 1867 ppm, benefiting from the synergistic effect between the catalyst and discharge that promotes generation of active species and conversion of intermediates.

Environmentally friendly

Using air and water as raw materials, the plasma-driven nitrogen fixation avoids the high carbon emissions of the traditional Haber–Bosch process.

Applications

• plasma catalytic nitrogen fixation：Replaces the conventional Haber–Bosch process, reducing energy consumption and carbon emissions.
• green fertilizer synthesis：Converts generated NOₓ into nitrates for use as green fertilizer precursors.
• catalytic materials：CuCo₂O₄/NaY enhances generation and conversion of active species in the discharge system.
• environmental catalysis：Utilizes mild plasma conditions to reduce the environmental footprint of nitrogen fixation.
