Photoelectrocatalytic Degradation of Chlorpyrifos Wastewater Paired with Biogas SOFC Based on PrBaMn2O5+δ Electrodes

In recent years, photocatalytic oxidation (PEC) technology has been widely studied in the field of water pollution remediation as an effective way to accelerate the degradation rate of organic matter. However, the external electric field applied by commonly used PEC wastewater treatment tanks is mostly provided by external equipment, therefore the pollution reduction process is accompanied by inevitable additional energy consumption. Aimed to reduce energy consumption and carbon emission, we designed a PEC tank which gets the extra bias voltage input from a biogas solid oxide fuel cell (SOFC) based on PrBaMn2O5+δ electrodes. The PrBaMn2O5+δ (PBMO) double perovskite powder has mainly tetragonal phase in both reduced and oxidized atmosphere. The polarization resistances of the PBMO electrodes with PBMO|SDC functional layers were 0.08 and 0.78 Ω•cm2 in air and simulated biogas respectively. Using simulated biogas (70% CH4 and 30% CO2) with 3% water vapor as the fuel and ambient air as the oxidant, the SOFC power density can achieve 325.5 and 234.8 mW•cm−2 at 700 and 650°C, respectively. Using MoS2/Ti as photoanode for the PEC tank, with applied bias of 0.5 V in 0.02 M Na2SO3 electrolyte, and with pH=3, the degradation rate of chlorpyrifos (CPF) in PEC tank can achieve 99.7% after 4 hours.
