Zn-Al layered double hydroxides as efficient photocatalysts for NOx abatement
(Elsevier, 2019)
In this study,we report that layered double hydroxides (LDH) exhibited high photocatalytic activitiesin degrading NOx gases for the first time. ZnAl-CO3LDHs with a 1.5 to 3.0 Zn/Al ratio were prepared by ...
Cr3+ substituted Zn-Al layered double hydroxides as UV–Vis light photocatalysts for NO gas removal from the urban environment
(Elsevier, 2019)
The ZnAl-CO3, ZnAlCr-CO3 and ZnCr-CO3 LDH samples were studied as De-NOx photocatalysts in this work. Samples without Cr and increasing the presence of Cr3+ in the LDH framework in the 0.06, 0.15 and 0.3 Cr/Zn ratio were ...
Effects of Fe3+ substitution on Zn-Al layered double hydroxides for enhanced NO photochemical abatement
(Elsevier, 2020)
In this work the ability of ZnAlFe-CO3 layered double hydroxides (LDHs) as highly efficient UV-Vis light photocatalysts for the photochemical oxidation of NO gas was studied. LDHs with 3.5 to 4.1 M2+/M3+ and 0.33 to 1.55 ...
ZnO on rice husk: a sustainable photocatalyst for urban air purification
(Elsevier, 2019)
A cost-effective and sustainable De-NOx photocatalyst is prepared usingzinc acetate and rice husk. ZnO@SiO2samples are obtained from the calcination of a homogenised precursor mixture at 600 C. ZnO ...
Aqueous miscible organic solvent treated NiTi layered double hydroxide De-NOx photocatalysts
(Elsevier, 2021)
New efficient photocatalysts are required to remediate polluted urban atmospheres. We prepared a series of highly dispersed aqueous miscible organic (AMO) solvent treated NiTi layered double hydroxide (NixTi-AMO-LDHs (x = ...
Use of LDH- chromate adsorption co-product as an air purification photocatalyst
(Elsevier, 2022)
This work deals with the use of layered double hydroxides for a double environmental remediation. The residue obtained in the use of these materials as a chromate sorbent in water, was subsequently studied as a photocatalyst ...
