In this work, a g-C3N4/porphyrin nanocomposite was fabricated through the self-assembling of monomeric Tetrakis (4-carboxyphenyl) porphyrin (TCPP) molecules with g-C3N4 nanomaterials. The characterizing results showed a good distribution of TCPP nanofibers with a diameter of < 100 nm and several micrometers in length on the g-C3N4 nanoflakes’ surfaces. The prepared g-C3N4/porphyrin nanocomposite had two bandgap energies of 2.38 and 2.7 eV, which could harvest a wide range of photon energy in the light spectrum, particularly in visible light. The obtained C3N4/TCPP nanocomposite revealed a remarkable photodegradation efficiency toward rhodamine B dyes, with a RhB removing rate of 3.3 × 10−2 min−1. The plausible mechanism for the photocatalytic performance of the g-C3N4/porphyrin photocatalyst for the RhB dye’s degradation was also studied and discussed.

PET, one of the most commonly used plastics, presents significant environmental challenges due to its non-biodegradable nature. To address this, we developed a sustainable method to convert PET waste into high-performance activated carbon via chemical activation with phosphoric acid (H3PO4). The produced activated carbon was analyzed utilizing X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), nitrogen adsorption/desorption (BET), energy-dispersive X-ray (EDX), and Raman spectroscopy. The activated carbon produced had a macroporous architecture with a substantial surface area, pore diameter, and pore volume of 655.59 m2/g, 3.389 nm, and 0.120 cm3/g, respectively. The adsorption isotherm of activated carbon for phenol conformed to the Langmuir model, signifying single-layer adsorption with a maximal capacity of 114.94 mg/g, while the kinetic adsorption adhered to the second-order model at an optimal pH of 7. The study highlights the sustainable benefits of mitigating plastic waste pollution while producing a cost-effective and eco-friendly adsorbent for water treatment applications. This research underscores the potential for recycling PET waste into valuable materials for environmental remediation.

Vật liệu nanocompozit silica/polypyrol (SiO2/PPy) hiện nay được sử dụng rất rộng rãi ở trên thế giới cũng như trong nước. Vật liệu này đã được tổng hợp bằng phương pháp vi nhũ in situ nhằm ứng dụng trong lớp phủ hữu cơ bảo vệ chống ăn mòn cho thép CT3. Ảnh hưởng của dung môi đến các đặc trưng, tính chất của nanocpmpozit SiO2/PPy đã được nghiên cứu. Kết quả nghiên cứu cho thấy dung môi tổng hợp không ảnh hưởng nhiều đến cấu trúc và hình thái của vật liệu tổng hợp được. Nanocompozit SiO2/PPy-W tổng hợp trong dung môi nước có độ dẫn điện cao nhất (σ = 0,19 S.cm-1), cao hơn độ dẫn điện của SiO2/PPy-EW và SiO2/PPy-E được tổng hợp trong dung môi rượu/nước và dung môi rượu (0,14 và 0,11 S.cm-1 tương ứng).
