Summary: Rational design of graphitic carbon nitride (g-C3N4) engineered hematite (Fe2O3)/reduced graphene oxide (rGO) photocatalysts has been successfully employed for visible-light-driven photo-Fenton-like degradation of sulfamethoxazole (SMX). The optimal photocatalyst showed exceptional performance due to the successful integration of g-C3N4/Fe2O3/rGO, enabling efficient separation and migration of photoinduced charge carriers (e/h+). The study also optimized the photochemical decomposition efficiency by analyzing important reaction parameters such as catalyst loading, H2O2 dosage, pH, and temperature, and proposed a possible mechanism for SMX degradation based on the generation of reactive species and degradation intermediates.

Summary: To prepare low nitrogen content hydrochar, Na2SO3 and NaHSO3 were used as additives to remove nitrogen from sewage sludge during hydrothermal carbonization. The maximum removal efficiency of nitrogen in hydrochar can increase by 68.68% at 210 degrees C when 10% of Na2SO3 was added, indicating that Na2SO3 has a greater capability than NaHSO3. The key role of Na2SO3 is the degradation of extracellular polymeric substances (EPS) to release polysaccharides and destroy proteins structure, thereby inhibiting Maillard reaction and reducing nitrogen content in hydrochar.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.
