Synthesis and Structure of Copper Hydroxyphosphate and Its High Catalytic Activity in Hydroxylation of Phenol by H2O2

Phenol Hydroxylation over Cu-Containing LDHs and Their Calcined Forms: Profound Cobivalent Metal Influence

“…Elemental chemical analysis of the samples was determined using inductively coupled plasma emission spectrometry (ICPES; Perkin-Elmer, OES, Optical 2000 DV) by digesting the sample in minimum amount of concentrated HNO 3 .…”

Copper hydroxyphosphate as catalyst for the wet hydrogen peroxide oxidation of azo dyes

“…Xiao and coworkers first discovered its excellent catalytic properties for the oxidation of olefins and alcohols by molecular oxygen under air pressure [26], and hydroxylation of phenol, benzene, naphthol, and 2,3,6-trimethylphenol by hydrogen peroxide [27][28][29]. Electron spin resonance (ESR) investigation suggested that Cu 2 (OH)PO 4 decomposed hydrogen peroxide to generate a high concentration of hydroxyl radicals, which could be responsible for the high catalytic activity [27,28]. This implies that such a catalyst may be effectively used to degrade wastewater containing organic pollutants through the Fenton mechanism.…”

Synthesis of Cu2PO4OH Hierarchical Superstructures with Photocatalytic Activity in Visible Light

“…[12] Cu 2 PO 4 OH has been found to possess catalytic, [13] magnetic, [14] and optical properties [15] because of its special crystal structure. [12,16] In particular, novel catalytic properties of Cu 2 PO 4 OH for the oxidation of alcohols, [17] hydroxylation of phenol, [13] and epoxidation of styrene [18] have been investigated. These excellent catalytic properties originate from the OH species attached to the Cu sites, which act as adsorption sites on the catalyst surface.…”

“…These excellent catalytic properties originate from the OH species attached to the Cu sites, which act as adsorption sites on the catalyst surface. [16] Recently, it has been reported for the first time that Cu 2 PO 4 OH with complex morphologies could be formed by hydrothermal synthesis. [19] Using a wet-chemical method and without any surfactants or templates, various 3D hierarchical superstructures of Cu 2 PO 4 OH were synthesized by simply adjusting the pH.…”
