Facile Synthesis of Ni-Doped ZnO Nanoparticles Using Cashew Gum: Investigation of the Structural, Optical, and Photocatalytic Properties

Molecules, Journal Year: 2023, Volume and Issue: 28(23), P. 7772 - 7772

Published: Nov. 25, 2023

This work adopted a green synthesis route using cashew tree gum as mediating agent to obtain Ni-doped ZnO nanoparticles through the sol–gel method. Structural analysis confirmed formation of hexagonal wurtzite phase and distortions in crystal lattice due inclusion Ni cations, which increased average crystallite size from 61.9 nm 81.6 nm. These resulted growth point defects structure, influenced samples’ optical properties, causing slight reductions band gaps significant increases Urbach energy. The fitting photoluminescence spectra an increase concentration zinc vacancy (VZn) monovacancies (Vo) Zn cations were replaced by structure. percentage VZn for pure compound was 11%, increasing 40% 47% samples doped with 1% 3% respectively. In contrast, highest VO is recorded material lowest ions concentration, comprising about 60%. influence dopant also reflected photocatalytic performance. Among tested, Zn0.99Ni0.01O presented best result MB degradation, reaching efficiency 98.4%. Thus, recovered underwent reuse tests, revealing 98.2% dye confirming stability photocatalyst. Furthermore, use different inhibitors indicated that •OH radicals are main ones involved removing pollutant. valuable because it presents ecological gum, natural polysaccharide has been little explored literature.
