Novel TiO₂/graphene oxide functionalized with a cobalt complex for significant degradation of NO_x and CO

Abstract

A TiO2/FGO composite manifests high photocatalytic properties for NOx and CO removal as high as three times more than that of bare TiO2.

Synthesis of Mesoporous Pd-Doped TiO2 Templated by a Magnetic Recyclable Ionic Liquid for Efficient Photocatalytic Air Treatment

“…There is no synergistic effect such as competition or deactivation between CO and NO x at this level, in the combination state. We have previously reported catalytic performance as 10% for CO and 16% for NO x in TiO 2 thin film …”

Immobilization Impact of Photocatalysts onto Graphene Oxide

“…Recently, novel TiO 2 /GO functionalized with a cobalt complex for significant degradation of NO x and CO has been reported [53]. The cobalt-imidazole functionalized GO incorporating with the TiO 2 result in a notable decrease of the band gap and increased the sensitivity to visible light irradiation.…”

Design, synthesis, and catalytic performance of modified graphene oxide based on a cobalt complex as a heterogenous catalyst for the preparation of aminonaphthoquinone derivatives

“…[19][20][21] Silica (SiO 2 ) increases the corrosion resistance and thermal resistance of graphene oxide, which may improve the loading of catalytically active sites, having signicant application potential in different elds. [22][23][24][25][26][27] In addition, cobalt has obtained more attention because of being an earth-abundant metal, catalytic activities, 28,29 and photocatalytic H 2 production. 30 2-Hydroxy-1,4-napthoquinone (lawsone) has been known for almost 4000 years, which is present in the leaves of the henna plant, and it is a signicant source of natural dyes.…”
