Photothermal superhydrophobic coatings are ideal materials for high-viscosity crude oil adsorption or treatment. However, how to quickly prepare large-scale photothermal superhydrophobic coatings for real application is still a challenge. Here, we report that photothermal superhydrophobic copper foam with a water contact angle of 159.9° can be quickly prepared using a low-cost and easy-to-manipulate electroplating method within only 5 min, presenting a facile and fast approach to fabricate large-scale photothermal superhydrophobic materials. The prepared superhydrophobic copper foam showed good physical and chemical stability. Importantly, the superhydrophobic copper foam had good oil spill adsorption characteristics, and the adsorption capacity and efficiency for n-hexane (<ρwater) reached 6.48 g/g and 99%, respectively. The adsorption capacity and efficiency for dichloromethane (>ρwater) reached 9.42 g/g and 99.3%, respectively. In addition, the superhydrophobic copper foam possessed a good photothermal property, enabling it with the ability of crude oil adsorption, and each gram of copper foam could adsorb 11.326 g of crude oil. The excellent performance of this photothermal superhydrophobic copper foam prepared by the ultrafast electroplating approach should play a great role in the treatment of marine crude oil leakage pollution.

Porous metal wires are promising in various applications, such as catalysis, energy storage and conversion, electrochemical sensing, and so forth. However, controllable fabrication and structural tuning of porous metal wires remains a daunting challenge. Here, we report the fabrication of 3D porous silver wires based on a template-assisted electroless deposition (ELD) method using an electrospinning-derived elastomer yarn as the template. After the calcination, the elastomer yarn with the deposition of silver nanoparticles can be converted into a 3D porous metallic silver wire with a conductivity higher than 3600 S/cm and a porosity of 86%. The porous structure of the wire could be tuned by changing the repeating cycles of the ELD process for loading silver nanoparticles. More importantly, the electrospinning-based fabrication strategy enables us to incorporate an insulating fibrous layer on the silver wire to impart advanced functionalities. As a proof of concept, a porous silver wire containing a concentric layer of SiO2 microfibers was prepared, and its application as a wire-shaped capacitor for liquid sensing was demonstrated. Benefitting from its completely inorganic nature, high porosity, and chemical stability, the composite wire could sense various organic solvents as well as aqueous solutions with high sensitivity, reliability, and long-term-use stability.

Graphical Hydrogen evolution reaction : A strategy of electroless plating of transition metal boride with high boron content to fabricate binder-free catalytic electrode with superior HER activity has been realized. Facile deposition of transition metal boride (TMB) with high-boron content as highly efficient hydrogen evolution reaction (HER) electrocatalyst has been realized by a facile one-step electroless-plating (EP) method. Boron content of the TMB catalyst shows an appreciable impact on its intrinsic HER activity. NiB/NF electrode with thin amorphous nickel boride (NiB) deposition on nickel foam (NF) required overpotential of only 41.2 mV to deliver a current density of 10 mA cm −2 for HER in 1.0 M KOH alkaline electrolyte. Meanwhile, this kind of electrode also shows satisfied stability which can work at large current density of 1000 mA cm −2 for over 72 h without performance degradation. The advance on the TMB electrode may pave a way to the development of practical electrodes for water splitting.

Synthesizing high performance and affordable nickel-based electrocatalysts has been one of the research hotspots in the field of clean energy conversion. Herein, facile electroless plating accompanied with mild impregnation method is explored to synthesize petal-like Ni(OH) 2 flakes on carbon cloth (CC) for electrocatalytic alkaline hydrogen evolution reaction (HER). Notably, the optimal Ni(OH) 2 /CC electrode has outstanding HER activity requiring only 24.6 mV vs . RHE of overpotential to reach 25 mA cm −2 of current density, and only 101.5 mV vs . RHE of overpotential to reach 100 mA cm −2 . Meanwhile, the 25-h stability test results performed well. This is primarily due to its plentiful interfacial contact, favorable surface morphology of ultrathin and dense nanosheets array, and rapid electron transport . Overall, this study provides a viable approach for the development of efficient, low-cost, hydrophilic nickel-based catalysts for electrocatalytic water splitting applications.

This study reports an efficient electroless plating approach using an amino-alcohol precursor to synthesize the oxidation stable copper@silver (Cu@Ag) core–shell nanowires. The synthesized nanowires were characterized by different techniques. The as-synthesized nanowires were used to fabricate transparent flexible electrodes (TFEs) and transparent stretchable heaters (TSHs). The nanowire network on the substrates was sintered using the 5% aqueous solution of H2O2, which welded the nanowires at their junction and strongly attached to the substrate. Therefore, the optical-electrical performance (∼13 Ω sq–1 @ 89% transmittance), oxidation stability, and mechanical flexibility of as-prepared TFEs and TSHs were improved to a large extent. In addition, the performance of the TSHs in terms of high-saturation temperature and stability against repeated stretching cycles upon 20% mechanical strain temperature are also enhanced. The overall processing strategy was suitable to synthesize the Cu@Ag core–shell nanowires and to fabricate the stable TFEs and TSHs for modern electronic and thermoelectric devices.

Exploring high-efficiency and stable monolithic structured catalysts is vital for catalytic combustion of volatile organic compounds. Herein, we prepared a series of Pd/δ-MnO2 nanoflower arrays monolithic integrated catalysts (0.01–0.07 wt% theoretical Pd loading) via the hydrothermal growth of δ-MnO2 nanoflowers onto the honeycomb cordierite, which subsequently served as the carrier for loading the Pd nanoparticles (NPs) through the electroless plating route. Moreover, we characterized the resulting monolithic integrated catalysts in detail and evaluated their catalytic activities for toluene combustion, in comparison to the controlled samples including only Pd NPs loading and the δ-MnO2 nanoflower arrays. Amongst all the monolithic samples, the Pd/δ-MnO2 nanoflower arrays monolithic catalyst with 0.05 wt% theoretical Pd loading delivered the best catalytic performance, reaching 90% toluene conversion at 221°C at a gas hourly space velocity (GHSV) of 10,000 h−1. Moreover, this sample displayed superior catalytic activity for o-xylene combustion under a GHSV of 10,000 h−1. The monolithic sample with optimal catalytic activity also displayed excellent catalytic stability after 30 h constant reaction at 210 and 221°C.

Developing composite materials with a rational composition structure has been a critical strategy to obtain superior electromagnetic (EM) wave absorption materials. CoNi/MoSe 2 composites were synthesized by a two-step method in this work. Firstly, the flower-like MoSe 2 was synthesized by hydrothermal method , and then the CoNi alloy was loaded on the MoSe 2 surface by an electroless plating method. It is worth noting that in this paper, PdCl 2 was not used for activation during the electroless plating process, and the flower-like structure of MoSe 2 was not destroyed. In order to investigate the effect of different Co/Ni molar ratios on the absorption performance of the CoNi/MoSe 2 composites, three samples with Co to Ni molar ratios of 1:3, 1:1, 3:1 and two other samples with only one metal (Ni or Co) were prepared. The analysis results show that the minimum reflection loss(RL) value of Ni/MoSe 2 is −18.01 dB and the maximum effective absorption bandwidth(EAB) of Co/MoSe 2 is 2.16 GHz. In comparison, the CoNi/MoSe 2 composite exhibits the best EM wave absorption performance when the Co/Ni ratio is 1:3, and the minimum RL can reach −48.6 dB at a matching thickness of only 1.8 mm. And when the matching thickness is 1.4 mm, the broadest EAB is 3.76 GHz. Therefore, this work provides a new research idea for the design of broadband and efficient EM wave absorbers.

Several Ni-W-P-TiO 2 nanocomposite coatings were developed by the sol-enhanced electroplating method. The phase and elemental compositions of coatings were determined, and the surface and cross-section morphology were characterized. The mechanical and corrosion performance were systematically tested. The results revealed the addition of 5 ml·L −1 TiO 2 sol caused a compact coating surface, while higher concentrations of TiO 2 reduced the coating thickness and led to the inferior surface microstructure. The comparison in physiochemical properties of prepared coatings confirmed the superior performance of the Ni-W-P-TiO 2 nanocomposite coating at 5 ml·L −1 TiO 2 sol addition. Under this condition, the best mechanical properties were achieved when abrasive wear was the dominating wear-resistance mechanism, and the best corrosion resistance was obtained due to its smooth and compact surface microstructure.

A heterogeneous catalyst, cobalt-modified natural zeolite prepared by electroless plating technique (ECM-Co-NZ), was fabricated as a peroxymonosulfate (PMS) activator for enhancing the oxidative degradation of atrazine (ATZ) in aqueous media. SEM, EDS, BET, XRD, Py-DRIFT, H 2 -TPR and XPS techniques were applied to characterize the features of the synthesized catalyst and conventional impregnation sample for comparison. Then, the catalytic activity and recyclability of two materials were investigated comparatively. The results show that ECM-Co-NZ has a better catalytic performance as well as a longer operational life, and complete removal of ATZ can be achieved in 14 min in ECM-Co-NZ/PMS system. Further, the effects of key factors including Co mass loading, calcination temperature, catalyst dosage, PMS dosage, initial pH and ATZ concentration on ATZ removal and Co leaching in ECM-Co-NZ/PMS system were elucidated in details. In addition, reactive oxygen species generated in the oxidation process were identified by radical scavenging test, byproduct detection and fluorescent probe technique. The results reveal that both hydroxyl and sulfate radicals were contributed to the degradation of ATZ, but sulfate radical had dominant role in controlling the ECM-Co-NZ/PMS oxidation system. Finally, the reaction mechanism and possible ATZ degradation pathways were discussed based on the experiment results and previous literature.
