Major Contributions

1. Synthesis of Carbon-Bridged g-C3N4 :
The study developed a novel carbon-bridged g-C3N4 by using oxamide, malonamide, and succinamide as carbon linkers. This synthesis improved the photocatalyst's light absorption and reduced charge recombination, thereby enhancing its efficiency in degrading tetracycline.

2. Integration with 3D-Printed Al2O3 Frameworks :
The research introduced a self-developed vat photopolymerization 3D printing technique to create alumina frameworks that support the carbon-bridged g-C3N4. This integration not only provided a robust support structure but also allowed for easy recycling and reuse of the photocatalyst, maintaining high mechanical strength and structural stability.

3. Enhanced Photocatalytic Performance :
The carbon-bridged g-C3N4 supported on the 3D-printed alumina framework demonstrated a high tetracycline removal rate of 85-90%. This system showed significant potential for environmental remediation due to its effective degradation process, which involves step-by-step oxidation, deamination, and mineralization.


主要貢獻

1. 碳橋g-C3N4的合成：
本研究開發了一種新型的碳橋g-C3N4，使用草酰胺、丙二醯胺和琥珀酰胺作為碳連接劑。這種合成方法提高了光催化劑的光吸收能力並減少了電荷復合，從而增強了其降解四環素的效率。

2. 與3D列印Al2O3框架的整合：
研究引入了一種自研的光聚合立體印刷技術來創建支撐碳橋g-C3N4的氧化鋁框架。這種整合不僅提供了堅固的支撐結構，還使光催化劑易於回收和重複使用，保持高機械強度和結構穩定性。

3. 增強的光催化性能：
支撐在3D打印氧化鋁框架上的碳橋g-C3N4展示了85-90%的高四環素去除率。由於其有效的降解過程，包括逐步氧化、去胺和礦化，該系統在環境修復方面展現了顯著潛力。
