“…Moreover, solvent affects the growth of BiOX crystals, which also decides the photocatalytic performance. By using a hydrolysis method, Hu et al 36 synthesized BiOCl photocatalyst for degradation of atenolol (ATL), and the removal efficiency reached nearly 100% within 60 min. Song et al 37 synthesized BiOCl nanosheets for degradation of perfluorooctanoic acid (PFOA).…”

Electrochemical oxidation of β-blocker atenolol (ATL, 100 ppm) at different applied current densities (33, 50 and 83 mA•cm -2 ) using a reactor divided by an ion-exchange membrane and an undivided one was investigated. Two types of anodes were used for this purpose: a boron-doped diamond (BDD) anode and new low-cost ceramic electrodes made of tin dioxide doped with antimony (Sbdoped SnO2). Degradation was assessed using a high performance liquid chromatography, while mineralization by measuring total organic carbon (TOC) dissolved in sample. Except for the lowest current density, ATL was completely 2 degraded for both reactors and electrodes. The highest percentage of TOC eliminated (89%) was obtained at the highest applied current density with the BDD electrode in the divided reactor. The presence of the cation-exchange membrane prevented the reduction of both the electrogenerated oxidizing species and the oxidized organic compounds and enhances the electro-oxidation kinetic reaction.In order to study the influence of the supporting electrolyte, three different concentrations of sodium sulfate (0.014, 0.05 and 0.1 M) were tested in the undivided reactor with both electrodes. The results showed that an increase in the concentration of the supporting electrolyte improves the mineralization of ATL for the BDD electrode and, on the contrary, worsens for the ceramic electrode.Accelerated service life tests were carried out for the ceramic electrode at 100 mA•cm -2 in 0.5 M H2SO4. Ecotoxicity tests using marine bacteria (Vibrio Fischeri) revealed that no toxic by-products were formed in any case.

“…Since the catalyst used in this study was doped with an appropriate amount of photocatalyst BiOCl and its effectiveness had been proved through the experiments above, it was apparent that this cooperative reaction mechanism was established. Photocatalysis generally follows zero‐order reaction kinetics because the catalyst does not directly participate in the reaction but generates electron‐hole pairs under the excitation of MW energy to indirectly participate in the reaction [34] . The specific proposed mechanism is shown in Figure9.…”

Microwave‐assisted Fenton process over a high microwave‐responsive catalyst (Fe3O4−BiOCl) was developed. The morphology, composition and magnetic recovery of the prepared catalyst were analyzed. Correspondingly, the optimal reaction conditions were obtained and the catalyst had a good recovery performance. A good degradation result (COD removal efficiency=82.57 %, TOC removal efficiency=85.15 %, TN removal efficiency=80.86 %) was obtained with low energy consumption and chemical inputs, which proved that the system has a certain industrialization prospect. Furthermore, take p‐nitrophenol (PNP) as an example, The reaction mechanism of this process had been investigated. The reaction was divided into three stages: 1. Activation 2. Oxidation 3. Mineralization. In the Oxidation phase, the reaction followed zero‐order reaction kinetics model and the rate constant was 0.0642 mM s−1. To investigate the kinetics, a heterogeneous Fenton‐photocatalysis synergistic degradation mechanism based on experimental data was proposed.
