Hydrodechlorination of 4-chlorophenol in water with formic acid using a Pd/activated carbon catalyst

The Pd-catalyzed hydrodechlorination of chlorophenols in aqueous solutions under mild conditions: A promising approach to practical use in wastewater

“…[7][8][9][10][11][12][13][14][15]. The available literatures support the application of catalytic hydrodechlorination of chlorophenols as a feasible non-destructive waste treatment method that operates under mild conditions in liquid phases [16][17][18].…”

“…The available literatures support the application of catalytic hydrodechlorination of chlorophenols as a feasible non-destructive waste treatment method that operates under mild conditions in liquid phases [16][17][18]. In the hydrodechlorination reactions, chlorophenols could be converted into relatively non-toxic cyclohexanone and cyclohexanol in liquid phase [13,18].…”

A Highly Active Pd on Ni–B Bimetallic Catalyst for Liquid-Phase Hydrodechlorination of 4-Chlorophenol Under Mild Conditions

“…Plenty of methods have been developed for the elimination of chlorinated organics: incineration, reduction dechlorination [5,6], oxidation dechlorination [7][8][9][10], biodegradation, photochemical catalysis, and catalytic HDC [4,11,12]. From an economical and environmental point of view, HDC is the most effective and promising method, which could avoid the formation of more toxic compounds such as dioxins, phosgene, and chlorine.…”

“…Hoke et al [13] studied that the complete destruction of 4-CP over Pd/C was possible under mild conditions (307 K, 0.2 MPa) early in 1992. In the last 5 years, it attracted more attention on the preparation of more effective catalysts, in which Pd/C catalysts were the most commonly used [12,[14][15][16]. The catalysts involved are essentially from the group VIII, such as Pd, Pt, Ru, Rh, and Ni, among which Pd and Ni are the most widely used.…”

A simple and effective approach for catalytic reductive dechlorination of aromatic compounds

“…12 It is usually mediated by a transition-metal catalyst, 13 molecular hydrogen (H 2 ) in the metal-catalyzed reductive dechlorination, 14 or using the other hydrogen sources such as hydrazine, formic acid and its salts, etc. 15 Recently, the hydrodechlorination of polychlorinated biphenyls (PCBs) in water-isopropanol systems and in the presences of catalysts have also been studied.…”
