Synthesis of CuFeVO Nanoparticles to Produce 1,2,3-Triazoles by Azide-Alkyne Cycloaddition Reactions.

This paper presents the fabrication of novel CuFeVO nanoparticles (NPs) via a facile sol-gel method as efficient nanocatalysts (NCs) to produce azide-alkyne 1,3-dipolar cycloaddition compounds. The effect of the calcination time on the formation of NPs was investigated. The as-prepared NPs were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), electron-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and Brunauer-Emmett-Teller (BET) analyses.

S, N co-doped carbon quantum dots/TiO nanocomposite as highly efficient visible light photocatalyst.

In this paper, we report on the preparation of S, N co-doped carbon quantum dots (CQDs)/TiO nanocomposite using a hydrothermal process where S, N-CQDs were concurrently synthesized and anchored to the surface of the TiO. The prepared nanocomposite was carefully characterized to identify the morphology and structure, crystallinity, chemical composition and optical properties. The photocatalytic activity of the nanocomposite was investigated for degradation of acid red 88 (AR88) under visible light irradiation.
