The Haber process, crucial for artificial nitrogen fixation and population growth, enables ammonia and urea production from atmospheric gases, but requires harsh conditions and high energy inputs.
In this study, we present a novel approach to urea synthesis directly from CO2 and N2 using an acid-base co-doped graphene catalyst. By employing sonocavitation and nebulization synthesis (SNS), we create high-pressure, high-temperature reaction conditions via acoustic cavitation. Where acid and base sites interact with carbon dioxide and nitrogen. The acid component binds the reactants (CO2, N2), while the base site reduces the activation energy during the reduction process.
Enhance urea production, we focus on improving the current density of the catalyst. We aim to enhance electrochemical properties and increase the three-phase (gas, liquid, and solid) surface area. Consequently, we propose that our catalyst offers a sustainable approach to green urea synthesis.
