Sintesis Material Fotokatalis Covalenttriazine Framework (CTF) Boron Dan Aplikasi Pada Degradasi Zat Warna

---

CTF as a semiconductor polymer can be used as an alternative material for photocatalyst applications. Boron atoms (B) are an option to increase the effectiveness of the CTF catalyst in the photocatalysis process. This research synthesizes CTF with dicyanobenzene (DCB) and carries out boron doping using H3BO3 as a precursor. The catalyst materials are then denoted as CTF-B-1, CTF-B-2, and CTF-B-3. The aim of this research is to studies the photocatalyst perfomance of the catalyst after the addition of boron. The catalyst that has been successfully synthesized is characterized using X-ray diffraction (XRD), Surface Area Analyzer (SSA) with the Braunner-Emmet-Teller (BET) method, Field Emission Scanning Electron Microscope, and Energy dispersive X-ray spectroscopy (FESEM-EDX), Fourier Transform Infra-Red (FT-IR), Ultra Violet-Diffuse reflectance spectroscopy (UV-DRS), and Raman Spectroscopy (Raman). The best catalyst was CTF-B-2 in several photocatalytic degradation tests. The degradation efficiency was obtained up to 99.15% with a concentration of 10 mg/L with a reaction speed of 0.0187 min-1. The CTF-B-2 catalyst can properly degrade various odorants such as methylene blue, rhodamine b, and methyl orange. Apart from photocatalysts, CTF-B-2 can also activate oxidants such as PMS and H2O2 and produce additional active radicals such as sulfate and hydroxy radicals which can degrade dyes. The photocatalytic reaction using CTF-B-2 predominantly produces O2·- which will be involved in the degradation reaction. Reusing the CTF-B-2 catalyst resulted in an efficiency reduction of below 5%.
