Preparation of macro-porous 3D boron-doped diamond electrode with surface micro structure regulation to enhance electrochemical degradation performance

Dongtian Miao et al.

Summary: Boron-doped diamond (BDD) is considered an excellent electrode material, with a specific surface area being a crucial factor in its electrocatalytic performance. A 3D BDD structure, Cu/W/BDD, showed significantly higher electrochemical active surface area compared to a 2D planar structure, resulting in enhanced efficiency in removing tetracycline hydrochloride (TCH) and total organic carbon (TOC). The energy consumption and fluid dynamics of the 3D structure were identified as key factors in its superior degradation performance.

Advanced Treatment of Phosphorus Pesticide Wastewater Using an Integrated Process of Coagulation and Ozone Catalytic Oxidation

Shengping Cao et al.

Summary: Conventional pretreatment and secondary biochemical treatment are ineffective in removing phosphorus from phosphorus-containing pesticide wastewater. In this study, coagulation-coupled ozone catalytic oxidation was used to treat the secondary biochemical tailwater from such wastewater. The results showed that a combination of coagulation and ozone catalytic oxidation effectively removed COD, TP, and chromaticity from the wastewater, indicating great potential for application in treating this type of wastewater.

Peroxymonosulfate activation by algal carbocatalyst for organic dye oxidation: Insights into experimental and theoretical

He Wang et al.

Summary: This study investigates the preparation of nitrogen-doped algal carbocatalyst (N-C) and the mechanism of radical and nonradical pathways in the N-C/PMS system. The results show that N-C prepared at 800 degrees C exhibits optimal degradation performance for methylene blue. The involvement of both radical and nonradical pathways in the degradation process is confirmed. Additionally, the correlation between graphitic N and nitrogen vacancy with the MB removal rate is identified. This work provides new insights into the role of nitrogen-dopants and nitrogen vacancies in carbocatalyst activation and advances the understanding of algal biomass utilization.
