“…Ray et al have reported immobilization of salicyladimine complex onto amorphous silica and MCM-41 for evaluation of their efficacies towards hydroxylation of phenols. They found MCM-41 supported catalyst showed a higher phenol conversion than the amorphous silica, which is due to higher surface area of MCM-41 [30]. The mechanism of phenol hydroxylation is known to proceed via a redox mechanism involving a Fe(III)/Fe(II) redox pair which is illustrated in Scheme 3.…”

“…Moreover, a strong interfacial interaction between nickel oxide (NiO) and activated carbon is highly desired to facilitate the charge transfer between the two components, which can enhance the electrocatalytic performance. Nickel(II) salicylaldimine, amine, imidazole and tetraazamacrocycle complexes have been successfully used as catalysts in the oxidation of phenol to catechol and hydroquinone (Abbo et al, 2004;Ray et al, 2007;Salavati-Niasari and Bazarganipour, 2006;Bansal et al, 2010).…”

“…Catechol and hydroquinone are used in a large number of applications in the modern chemical industry, such as pharmaceuticals, photography and polymer production [1]. Catechol and hydroquinone are commonly synthesized by a phenol hydroxylation reaction using H 2 O 2 as an oxidant [2]. H 2 O 2 has many advantages, such as having a high active oxygen content and being a stable reagent and a green compound that only results in water as waste product from the reaction [3].…”

“…TS-1 has a relatively high phenol conversion activity and it can lessen the production of tar and other side products that are potential pollutants [2]. However, TS-1 has a low reaction rate and catalytic selectivity in oxidation reactions because of its hydrophobic nature [9].…”
