摘要：

In this study, L-arginine-capped cadmium telluride (CdTe) nanoparticles (NPs) were successfully prepared using the hydrothermal process. The formation, morphology, and physicochemical properties of the prepared samples were successfully characterized using different analytical techniques, such as X-ray diffraction (XRD), Fourier transforms infrared (FTIR), High-resolution transmission electron microscopy (HRTEM), Ultraviolet-visible spectroscopy (UV-Visible) and Photoluminescence spectroscopy (PL). The photocatalytic activity of the prepared samples was evaluated by the degradation of methyl orange (MO) dye under visible-light. It was observed that 86.3% MO dye removal efficiency was achieved over L-arginine-capped CdTe NPs, which was 1.6 times higher than that of the bare CdTe NPs. Interestingly, the L-arginine-capped CdTe photocatalyst was recycled in four consecutive runs without significant activity loss. (C) 2020 Elsevier B.V. All rights reserved.
