Synthesis of Vanadium Oxide Supported on Reduced Graphene Oxide for De-Nox

Abstract

Graphene has many excellent properties such as wide specific surface area, outstanding electrical mobility, and high optical transmittance. Due to these advantages, which make graphene appropriate matrix supporting vanadium for the nanocomposite. Also, depending on the synthesis process, graphene can be obtainable graphene oxide (GO) and reduced graphene oxide (RGO). Moreover, RGO has been receiving increased attention due to its nature to easily reduced to graphene, referred to as RGO, which has wide application. The purpose of this study is to investigate the characteristic of V2O5 deposited on RGO. The nanocomposite of vanadium oxide (V2O5) supported on RGO was prepared by different methods of evaporation, impregnation and impregnation with dispersant. XRD, SEM, TEM, BET and TGA analyses were used to investigate their chemical stability, and amount in vanadium oxide on RGO. This synthesis of V2O5 supported RGO is expected to be used as selective catalytic reduction (SCR) catalyst for De-NOx.

Synthesis of oxygen functionalized carbon nanotubes and their application for selective catalytic reduction of NOx with NH3

“…This suggests that when CNTs are used as a support, in addition to the high specic surface area affecting the dispersion of catalytic particles, the catalyst efficiency is also increased by the presence of sufficient surface functional groups that effectively disperse the nanoparticles without aggregation. 45,46…”

Recent trends in vanadium-based SCR catalysts for NOx reduction in industrial applications: stationary sources

“…Therefore, many researchers have used various dispersants to improve dispersibility [ 82 – 86 ]. It is important to finely disperse catalytically active materials without aggregation to enhance the catalyst acid sites, achieve a high specific surface area, and prevent sintering at high temperatures [ 87 – 89 ]. In addition, significant research has been conducted for improving catalyst dispersibility using supports with abundant functional groups [ 90 ] and having high efficiency and durability by dispersing single-atom catalysts on a support [ 91 ].…”
