Preparation of spike-like palladium nanoparticle electrode and its dechlorination properties

Metallic nanoparticles for electrocatalytic reduction of halogenated organic compounds: A review

“…Indeed, Pd NPs electrodeposited on an interlayer film composed of polyaniline-nickel hexacyanoferrate-carbon nanotubes appeared as -spike-like‖ clusters. In addition, the electrodes prepared with an interlayer exhibited a much higher catalytic activity towards the dechlorination of 4-chlorophenol than those without interlayer [160]. Similar effects were reported with the utilization of various interlayers, such as carbon nanotubes [100,161], graphene-based materials [162][163][164], or titanium-based interlayers [165,166] (2) Component's molecular structure effect…”

“…It was also reported that the shape, activity and stabilization of the NPs can be greatly influenced by the utilization of an interlayer [160]. Indeed, Pd NPs electrodeposited on an interlayer film composed of polyaniline-nickel hexacyanoferrate-carbon nanotubes appeared as -spike-like‖ clusters.…”

Recent advances in electrocatalysts for halogenated organic pollutant degradation

“…Furthermore, to exploit the most intrinsic properties of Pd catalysts, a robust interlayer with a high specific surface area is often required. 189,190 For instance, Li et al 186 (Fig. 8 a).…”

Rational Design and Structural Regulation of Robust Catalysts for Electrocatalytic Hydrodechlorination: From Nanostructures to Single Atoms

“…By controlling the size and morphology of the nanoparticles, it is possible to achieve the desired surface structure to improve catalytic performance. The size of nanoparticles can significantly affect their catalytic activity, and a higher surface area and smaller particle size can expose more active sites. − At the same time, nanoparticles with a different atomic arrangement on the surface could expose different crystal surfaces, which would affect the adsorption of pollutants on the catalyst or affect the bond breaking in the catalyst surface reaction, thus changing the catalytic activity and selectivity. , Wang et al prepared the composite electrode by electrodepositing palladium nanoparticles on the interlayer membrane composed of polyaniline-nickel hexacyanoferrate-carbon nanotubes and used 4-chlorophenol (4-CP) as a model pollutant to study the EHDC performance. The results show that the Pd nanoparticles with peaklike clusters exhibit excellent performance, and 98.59% 4-CP can be removed within 120 min at a low loading (0.53 mg/cm –2 ).…”
