“…00-004-0802) observed from Figure S9c. 48 Figure 3a displays the survey XPS spectra for Au@NiO|Ni (red curve), Pd@NiO|Ni (blue curve), and Pt@NiO|Ni (green curve) electrodes, confirming the presence of Au, Ni, and O at the Au@NiO|Ni electrode, Pd, Ni, and O at the Pd@NiO|Ni electrode, and Pt, Ni, and O at the Pt@NiO|Ni electrode. From the XPS survey spectra, the atomic percentage of the elements was found to be 0.4:19.3 for Au to Ni, 8.7:7.0 for Pd to Ni, and 0.1:13.2 Pt to Ni (Table S1).…”

Design of both efficient and durable electrode materials is key for oxygen reduction reaction (ORR) in influencing the efficacy of both fuel cells (FCs) and metal-air batteries (MABs). Here, we demonstrate the uniform dispersion of noble metals like (Au), palladium (Pd), and platinum (Pt) on nickel oxide on nickel electrodes (NM@NiO|Ni) for promoting ORR under alkaline electrolytes through engineering the electronic structures of noble metals as active sites. The NM@NiO|Ni electrodes are fabricated using acid etching followed by the galvanic replacement reaction method. Nickel oxide functions as an appropriate and encouraging support that can intensely interact with noble metals for both high catalytic activity and stability improvement. The Pd@NiO|Ni electrode exhibits prominent electrocatalytic ORR performance with an onset potential (E onset ) of ∼0.98 V [vs. reversible hydrogen electrode (RHE)], reduction potential (E) of ∼0.88 V (vs. RHE), catalytic cathodic current density of ∼−0.125 mA cm −2 at ∼0.88 V (vs. RHE), and mass activity of ∼0.38 Ag −1 in 0.1 M KOH, among the other developed electrodes in this study. The introduction of Pd as a second constituent to the NiO nanostructures enhanced the ORR performance expressively. The synergistic effects of Pd and Ni seem to possess a key impact on both catalytic ORR activity and stability. This strategy for enriching the catalytic active sites and the durability of the electrocatalysts demonstrates great potential for FC and MAB applications.

In the context of developing a more livable environment, people are paying more attention to the pollution problem. As the consumption of water resources increases, water pollution is one of the most serious problems people need to pay attention to the most. However, traditional methods cannot meet the requirements of treating wastewater while recovering resources. In this review, the application of electrocatalytic technology in municipal wastewater treatment is discussed. Specifically, the comparison between electrocatalysis and traditional methods is shown in this review. Various literatures on different types of materials of electrodes are included. Besides, two different types of electrodes and mechanisms of electrocatalysis and their application in multiple types of wastewater are also summarized. This review aims to arouse peoples attention to the wastewater problem and explore the further application of electrocatalytic technology in the future in order to rationally design new electrocatalytic systems for the recovery of energy and resources.
