Abstract Recently, many studies have been published regarding electrochemical oxygen reduction reaction for generating hydrogen peroxide (H 2 O ) using gas diffusion electrodes (GDEs) various applications. Sodium salts solved in deionized water were usually used as supporting electrolytes. In technical applications, however, tap water‐based electrolytes with hardeners are particularly relevant and only considered a few to date. this work, we investigated the influence of on H ‐generation at 150 mA cm −2 able show that scaling occurs predominantly GDE‐surface not its pore structure. With novel method synthesis by complexing agents bind hardeners, significantly reduce scaling. Even after 10 h operation, reactor still achieves faradaic efficiency (FE) above 70 % (>67 mg −1 ), comparable experiments without electrolyte. Furthermore, demonstrate electrochemically converted carbon‐based GDE behave inertly. If cell is operated rinsed acidic liquid (anolyte) between batches, can be completely avoided.

This study integrates macromixing and micromixing methodologies to characterize an electrochemical reactor with a gas diffusion electrode (GDE) based on computational fluid dynamics (CFD) simulations validated by residence time distribution (RTD) data. It experimentally evaluates two types of GDEs for H2O2 accumulation uses the CFD model evaluate in reactor. The tanks-in-series (T-I-S) provides qualitative understanding fluid's macroscopic behavior, while transition SST analyzes microscopic turbulence zones. reveals significant convergence current density, volumetric flow rate, GDE type production. optimal experimental configuration (carbon/PTFE/fabric Q = 50 L h–1) was evaluated through at different rates. These results improve our hydrodynamics offer prospects optimizing generation processes.

Most established synthesis routes in the chemical industry are based on high-energy-demanding processes and rely consumption of fossil fuels. Organic peracids, which can be used as ecofriendly highly effective disinfectants, typically synthesized by reaction a carboxylic acid hydrogen peroxide (H2O2), electrochemically with renewable electricity. In particular, use gas diffusion electrodes open new field for indirect on-demand electrochemical peracid production. this paper, implementation an in-cell various peracids building up improved performic (PFA) is described. H2O2 was obtained at high current densities 100 mA cm–2 directly reacted formate catholyte solution. The using buffered system 1 wt % H3PO4 ending 1.47 mol L–1 0.24 PFA efficiencies 37.5% 6.1% after 24 h electrosynthesis, respectively. Finally, conditions were successfully transferred, demonstrating first comprehensive approach to electrosynthesis introducing general route.
