The visible light-driven photocatalytic degradation of Alizarin red S using Bi-doped TiO₂ nanoparticles

Abstract

Ultrasonic assisted sol–gel synthesized Bi-doped TiO2 mesoporous nanoparticles with a good crystallinity and high surface area were prepared. The 1% Bi-doped TiO2 catalyst showed the highest photocatalytic activity under visible light.

Sunlight-driven photocatalytic degradation of non-steroidal anti-inflammatory drug based on TiO2 quantum dots

“…0 5), (2 1 1), (2 0 4), (1 1 6), (2 2 0) and (1 0 7) indices of TiO 2 , respectively. This observation confirms the existence of anatase phase [28,29]. No other peaks of rutile and brookite were detected in XRD plot.…”

Sb2O3–ZnO nanospindles: A potential material for photocatalytic and sensing applications

“…The photoluminescence study provides useful information about the recombination or trapping of charge carriers [38]. The room temperature photoluminescence (PL) spectrum of the Sb 2 O 3 -ZnO nanospindles is shown in Fig.…”

Sm-Doped Tio2 Nanoparticles With High Photocatalytic Activity For ARS Dye Under Visible Light Synthesized By Ultrasonic Assisted Sol-Gel Method

“…6(b)). The highest photocatalytic efficiency for 1% SmT photocatalyst is due the small grain size, large surface area, inhibition of the e -/h + recombination and the increase in the absorption of visible light as explained in the XRD and TEM, BET isotherms, XPS spectra and UV-vis DRS respectively 35 .…”
