摘要：
The scale-up synthesis of HOfrom HOvia a dielectric barrier discharge(DBD)under ambient conditions was studied.A plasma reactor consisting of multiple parallel DBDtubes was designed to scale up the HOsynthesis.The number of tubes had no significant effecton the discharge mode,and no decay occurred in HOselectivity during the scale-up process.These advantages made this technology more stable and efficient.The reactor’s energy efficiencyincreased with the number of tubes and reached 136 g HO/kWh in the four-tube reaction.Thetotal energy efficiency was limited by the extremely low energy transfer efficiency of power supply,and might be enhanced by optimizing the impedance matching between the power supply and thereactor load.As a result,an assembly of multiple DBD tubes may provide a viable route for thescale-up synthesis of HOby a non-equilibrium plasma.
