Catalytic oxidation of chlorobenzene over noble metals (Pd, Pt, Ru, Rh) and the distributions of polychlorinated by-products

High-yield synthesis of Ce modified Fe–Mn composite oxides benefitting from catalytic destruction of chlorobenzene

“…Ce 4+ has strong oxidizing properties, which can oxidize Mn x+ and Fe x+ . At the same time, Ce 3+ is oxidized to CeO 2 by O 2 in the air 16 (eqn (3)-(5)).…”

“…12 By comparison, catalytic oxidation is regarded as one of the most promising techniques for elimination of chlorinated aromatic compounds at much lower temperatures (<500 C), due to its high efficiency, less harmful by-products (e.g., CO 2 , HCl, Cl 2 ), and low energy consumption. 11,[13][14][15][16] Catalysts based on noble metals, perovskites, and transition metal oxides have been developed for the catalytic oxidation of chlorinated aromatic compounds. 11,16,17 Noble metals are expensive and always deactivate owing to chlorine (Cl) poisoning during catalytic oxidation processes, which limits their practical large-scale application.…”

Advances in Catalytic Oxidation of Volatile Organic Compounds over Pd-Supported Catalysts: Recent Trends and Challenges

“…Ning and coworkers investigated the catalytic performance of noble metal (Pd, Pt, Ru, and Rh) catalysts for chlorobenzene catalytic destruction. The reaction mechanism was proposed based on the result of the in situ FTIR analysis (Liu et al, 2019). The oxidation reaction started with the adsorption of chlorobenzene on the catalyst surface.…”

Highly Selective Catalytic Dechlorination of Dichloromethane to Chloromethane over Al−Ti Mixed Oxide Catalysts

“…These are also recognized as chlorinated volatile organic compounds (CVOCs), which are very harmful to the environment and human body, thus its exposure should be suppressed. The oxidative decomposition of CVOCs by reacting them with dioxygen can convert CVOCs to harmless substances such as carbon dioxide, in which a number of efficient catalysts have been studied for the catalytic oxidation of CVOCs, including zeolites, [8][9][10] perovskites, [11][12][13][14] noble metals [15][16][17][18][19] and metal oxides. [20][21][22][23][24][25][26][27][28][29] The complete oxidation of CVOCs to CO 2 would be efficient approach to solve the environmental problems of CVOCs, but another potential way to convert the CVOCs into value-added intermediates could be considered.…”
