Bio-inspired oxidation of methane in water catalyzed by N-bridged diiron phthalocyanine complex

Abstract

A stable mu-nitrido diiron phthalocyanine activates H2O2 to oxidize CH4 in water at 25-60 degrees C to methanol, formaldehyde and formic acid as evidenced using 13C and 18O labelling.

Reaction of μ-Nitrido Diiron(IV) Phthalocyanine and Dicumyl Peroxide

“…Исследования, проведенные в последнее время, свидетельствуют о значимых катали-тических свойствах стабильного μ-нитридодимерного фталоцианината железа в реакциях окисления алифатических и ароматических углеводородов. [2,6,[8][9][10][11][12] Каталитическая активность N-мостиковых структур во многом обусловлена стабилизацией активных частиц, образующихся при взаимодействии µ-нитридодимерных комплексов с окислителями, а также высокой устойчиво-стью указанных соединений в условиях каталитической реакции.…”

An Overview of Recent Advances of the Catalytic Selective Oxidation of Ethane to Oxygenates

“…Whilst a number of homogeneous catalytic systems have been reported for the activation of methane, the catalytic oxidation of ethane using homogeneous catalysts has rarely been studied [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65].…”

“…Another class of catalysts which have been reported as active for the partial oxidation of short chain alkanes with H2O2 are iron phthalocyanine complexes [50,51,93,94]. Whilst to date most research has focussed upon the partial oxidation of methane, Sorokin and co-workers have recently reported that the SiO2 supported phthalocyanine (FePc)2N/SiO2 shown in Figure 3 affords high reaction yields (34%) with appreciable acetic acid selectivity (69%) in the aqueous phase at the low temperature of 60 °C [95].…”

Gold anion catalysis of methane to methanol

“…Recently, the negative ion resonances that characterize the electron elastic scattering TCSs for atomic Au have been proposed as the fundamental mechanism driving nanoscale catalysis [6,7]. The catalytic combustion of methane, the main component of natural gas, including its conversion to useful products, has recently received extensive experimental and theoretical attention because of the potential to reduce pollutant emissions and synthesize useful chemicals [30][31][32][33][34][35][36] [29].…”
