Abstract
The current investigation studies the covalent triazine framework (CTF) with copper modification. The analyses comprised several characterizations including, i.e. FTIR (Fourier Transform Infrared Spectroscopy), XPS (X-ray Photoelectron Spectrometer), SEM/EDX (Field Emission Scanning Electron Microscopy/Energy-dispersive X-ray), XRD (X-ray Diffractometer), BET (Brunauer–Emmett–Teller) isotherm and surface area, and UV–vis DRS (Diffuse Reflection Spectroscopy). Additionally, the effect of additional oxidants and scavengers is studied. The copper-modified CTF (CTF-Cu) was found to have favorable properties for photocatalysis purposes compared to pristine CTF-1. The copper modification extends visible light absorption, reduces estimated band gap energy, and modifies the microstructure and chemical composition of the pristine CTF-1 facet. Conclusively, the CTF-Cu exhibited higher performance for methylene blue degradation.
