Facile template fabrication of Fe-Mn mixed oxides with hollow microsphere structure for efficient and stable catalytic oxidation of 1,2-dichlorobenzene

Recent Progress of Thermocatalytic and Photo/Thermocatalytic Oxidation for VOCs Purification over Manganese-based Oxide Catalysts

“…Compared with the corresponding single oxides synthesized by similar methods, the Mn-based oxide composites exhibit excellent catalytic performance, which can be attributed to the higher surface oxygen mobility, the generation of more oxygen vacancies, or the synergy of improved oxidation capacity. Various composites such as manganese oxides based heterostructures, − manganese oxides coupled with perovskite oxides, , incorporation of MnO x with other metal oxides, − manganese oxides compounded with carbon materials, − and multiple composites, − illustrated the enhanced catalytic oxidation performances of VOCs. A summary of these composites and their performances and reaction conditions is shown in Table , respectively.…”

TiO2 nanosheet supported MnCeOx: a remarkable catalyst with enhanced low-temperature catalytic activity in o-DCB oxidation

“…The weak peaks at 2320 cm −1 and 2355 cm −1 were assigned to the CO 2(Silva et al 2018), indicating that the intermediate formates and acetic species were further converted to CO 2 by deep oxidation. Besides, in addition to the intermediates mentioned above, the o-DCB catalyzed oxidation process is usually accompanied by the formation of H 2 O, which can be explained from our previous studies(Ma et al 2019).…”

Fabrication of a multi-dimensional CoFeOx catalyst for the efficient catalytic oxidation elimination of o-dichlorobenzene

“…Appropriate use and control are important to the release of CVOCs, so complete elimination and destruction of volatile organic compounds in exhaust gases are necessary. 5,6 Catalytic combustion of CVOCs is a low-cost and high-efficiency method to convert CVOCs into H 2 O, HCl and CO 2 . Due to the high removal efficiency of catalytic combustion technology, it has been widely used in the field of exhaust gas treatment, and even traces of CVOCs can be eliminated completely at low temperatures (o500 1C).…”

“…Chlorine poisoning leads to the loss of catalytic combustion activity and reduces the catalytic efficiency of transition metal oxides. 5,10,19 The durability and stability of the catalyst are as critical as its selectivity and activity, as these properties have a significant impact on catalytic oxidation efficiency. 20,21 To solve the problems of catalyst poisoning and loss of active components caused by chlorine deposition, doping metal cations in the catalyst preparation process is a simple and practical method.…”
