Summary: This work presents a novel tubular g-C3N4 with a hierarchical core-shell structure achieved through the incorporation of phosphorous elements and nitrogen vacancies. The core is composed of randomly stacked ultra-thin nanosheets, enabling efficient electron/hole separation and visible-light absorption. This photocatalyst demonstrates outstanding performance in the photodegradation of rhodamine B and tetracycline hydrochloride under low intensity visible light, as well as remarkable hydrogen evolution rate under visible light. The introduction of phytic acid into the melamine and urea solution during hydrothermal treatment leads to the formation of this hierarchical structure, offering a facile and scalable approach for mass production.

Summary: Due to its abundant precursors, simple preparation, and environmental friendliness, nitrogen-doped carbon is regarded as a promising anode material for potassium-ion batteries (PIBs). In this study, nitrogen-doped carbon material (NC-2) was synthesized using exfoliated g-C3N4 as a precursor, combined with sucrose, and subjected to hydrothermal and high-temperature pyrolysis. NC-2 exhibited a high nitrogen content, porous layered structure, and large interlayer spacing. As the anode for PIBs, NC-2 demonstrated a high reversible capacity of 261.07 mAh g-1 at 0.1 A g-1 and an impressive rate performance of 153.36 mAh g-1 at 2 A g-1. The excellent performance of NC-2 can be attributed to its porous layered structure, enlarged interlayer spacing promoting ion diffusion, and the presence of abundant active sites due to nitrogen doping. These results indicate the great potential of NC-2 as a PIBs anode material.
