Electrochemical advanced oxidation process with simultaneous persulfate and hydrogen peroxide on-site generations for high salinity wastewater

Jucai Wei et al.

Summary: Organic contaminant abatement by upgraded electrochemical process is highly efficient. An electrochemical advanced oxidation process is developed by combining in situ electro-generation of persulfate on beta-PbO2 anode and hydrogen peroxide on carbon cathode. The presence of reactive species, such as 1O2, ·OH, and SO4·-, produced on-site contributes to the strong oxidant power and mineralization. The application of oxygen-depolarized electrode not only produces hydrogen peroxide but also reduces cell voltage and energy consumption.

Enabling direct H2O2 electrosynthesis of 100 % selectivity at 100 mA cm-2 using a continuous flow sulfite/air fuel cell

Jucai Wei et al.

Summary: The direct electrosynthesis of hydrogen peroxide from the air is a promising alternative to the energy-intensive anthraquinone process. However, current methods suffer from low productivity and high energy consumption. In this study, a continuous flow sulfite/air fuel cell with a sulfite depolarized anode is proposed as a direct synthesis strategy. By optimizing catalysts and cell parameters, the prototype cell achieved high selectivity and productivity, with low energy consumption. The desulfurization solution from the flue gas desulfurization process is applied as the anolyte, further enhancing hydrogen peroxide synthesis and recovering sulfur as fertilizer.

A sulfite/air fuel cell for H2O2 electrosynthesis

Jucai Wei et al.

Summary: In this work, a self-driven sulfite/air fuel cell was developed for H2O2 electrosynthesis by coupling the sulfite oxidation reaction with the 2e(-) route oxygen reduction reaction. An Au-Pd/C catalyst was synthesized and exhibited good activity and selectivity for the 2e(-) route oxygen reduction reaction. The fuel cell achieved an open cell voltage of 0.52 V and a discharge current density of 24.48 mA cm(-2) at 0 V. Ammonia desulphurization wastewater was utilized as the fuel, enabling cost reduction and energy and resource recycling.
