RESUMEN
In recent years, the research of phenylethynylcopper (PhC2Cu) in photocatalysis has attracted immense attention. However, its synthesis requires two steps extending over 9 days. In this paper, the successful preparation of PhC2Cu nanowires is reported using a highly rapid and facile one-step method directly using copper acetate and phenylacetylene as raw materials and ascorbic acid as reducing agent. The kinetic studies indicated that the synthetic reaction follows a pseudo-second-order equation through electrical conductivity. Comparative studies of the crystal structures, morphologies, and optical properties of PhC2Cu prepared by the traditional two-step and the current one-step methods were conducted using XRD, SEM, UV-Vis Drs, FT-IR, Raman spectra, and photocurrent. Meanwhile, the PhC2Cu nanowires exhibited excellent photocatalytic activity to degrade methyl violet (MV) and glyphosate. This facile and rapid method dramatically improves the preparation efficiency of PhC2Cu, and the obtained PhC2Cu also shows higher photocatalytic activity. This remarkable progress enables the possibility of large-scale and efficient preparation of PhC2Cu with high photocatalytic activity, indicating their excellent application prospect in photocatalysis.
