Summary: This study presents a visible-light-driven organic-inorganic S-scheme heterostructure photocatalyst with excellent performance in removing antibiotics from wastewater. By anchoring TCPP on the surface of Bi12O17Cl2, the S-scheme junction between TCPP and Bi12O17Cl2 was created, enhancing the visible-light response and accelerating the disintegration and conservation of photo-carriers. The resulting TCPP/Bi12O17Cl2 showed significantly improved photocatalytic activity and stability compared to Bi12O17Cl2. Through scavenging tests, LC-MS analysis, and toxicity calculation, the reactive radicals, degradation pathway, and eco-toxicity were elucidated. This research demonstrates the potential practicality of porphyrin-based S-scheme heterojunction photocatalysts for efficient antibiotic removal.

Summary: In this paper, yolk-shell structured magnetic multicomponent nanocomposites (MCNCs) were produced and their outstanding electromagnetic wave absorption performances (EMWAPs) were demonstrated. The as-prepared materials exhibited excellent absorption capabilities, broad absorption bandwidth, and thin matching thicknesses due to the unique structures and the synergistic effect between dielectric and magnetic loss. Furthermore, the materials maintained their specific structure even after thermal and hydrothermal processes, and MCNCs with different MoS2 contents could be synthesized by controlling the hydrothermal temperature.
