“…Contrasting the peaks in the range from 850 to 864 eV for 1J79 and HT-1J79 (Figure 2c), the initial Ni (852.4 eV) and NiO (855.0 eV) have transformed into NiOOH (855.9 eV) completely after in-situ etching. [13,14,40] As for O 1s (Figure 2d), three fitting peaks are identified as O 2À (529.8-530.1 eV), OH À (531.4-531.5 eV), and H 2 O (532.4-532.6 eV). [13] From the above characterization results, FeOOH and NiOOH are the main composition on the surface of nanocone arrays.…”

Nowadays, stainless steel (SS) based electrode has gained extensive interest for oxygen evolution reaction (OER) owing to its low-cost and high efficiency. However, the problem of hazardous Cr dissolving out from the SS during the surface treatment needs to be solved urgently. Herein, we report a kind of self-supported NiÀ Fe oxyhydroxide pagoda-shaped nano-cone array prepared through an environmentally friendly method, which can be developed as an electrocatalyst for OER with low overpotential, small Tafel slope, and good stability under alkaline condition. This route ensures good catalytic performance of the prepared electrode and eliminates the leach of Cr ion at the same time.

“…[227,228] In this latter case, the in situ activation of the electrode in the electrolyte enables self-healing thanks to the formation of an active oxide-based layer under controlled corrosion conditions. [229] However, in the Li-O 2 battery, one of the main issues is the corrosion of the metallic anode due to the dissolved O 2 and H 2 O coming from electrolyte decomposition even in absence of electrochemical reactions, which is a more severe problem with respect to other sealed LMBs because the cathodic compartment is exposed to air or oxygen. As reported, the presence of tiny amount of H 2 O promotes the very fast corrosion of the anode with the formation of unstable Li 2 CO 3 , Li 3 N, and LiOH-based layers by poorly reversible processes which also increase the electrode overpotential.…”

An improved lifetime can be achieved by exploiting higher intrinsic durability of the materials, or by repairing the deteriorated component and restoring its original properties. Indeed, in the last years, several attempts to improve the lifetime of widespread devices (prosthetics, batteries, solar cells, lighting devices, etc.) were reported. [4-8] However, traditional techniques (welding, gluing, patching) need in situ application of fresh healing materials, and are not applicable to many modern complex devices that require disassembly and targeted operations well beyond the expertise of the final user. Moreover, repair by specialized personnel may be impossible or unsustainable from an economic point of view. To overcome these problems, a radically new strategy that can pave the way for more durable materials is emerging: the concept of selfhealing (SH). [9] This term refers to those smart materials that can automatically restore some, or all, of their functions after having suffered of an external damage that degraded their original properties. This usually has to do with autonomous recovery of physical cracks, but may include a wider range of features prolonging the lifetime of a material/ device, which space from anticorrosion to bactericidal properties. [10,11] By tailoring an appropriate response of the system, it becomes possible to design a material that can respond to various external perturbations and accommodate their eventual disturbance. The idea at the base of this approach is usually defined as biomimetic, since it takes inspiration from nature and mimic it in solving complex technological problems. [12] During the years, many different materials or technologies, naively depicted in Figure 1a, have taken inspiration from nature (as Velcro tape which mimics tiny hooks on bur fruits, naturally ventilated facades that mime termites' mounds, hydrophobic lotus-leaf coatings, and iridescent or adhesive surfaces respectively inspired by butterflies and geckos) and self-healing is not an exception. [13-15] In fact, in nature many organisms are capable of healing damages and of restoring their functionalities: skin, bones, plants, and other living systems can sense any failure and reconstruct the injured biological part which recovers its original functionalities. [16-18] Since these features lengthen the life of natural living beings, analog mechanisms can be exploited in artificial self-healing materials to benefit the Major improvements in stability and performance of batteries are still required for a more effective diffusion in industrial key sectors such as automotive and foldable electronics. An encouraging route resides in the implementation into energy storage devices of self-healing features, which can effectively oppose the deterioration upon cycling that is typical of these devices. In order to provide a comprehensive view of the topic, this Review first summarizes the main self-healing processes that have emerged in the multifaceted field of smart materials, classifying them on the basis of t...

Nonprecious and effective electrocatalyst development is an essential requirement for boosting water-splitting efficiency to obtain clean and sustainable fuels for future renewable energy demands. Herein, we reported an ultrafast and feasible strategy for constructing an S-doped bimetallic iron/nickel oxy(hydroxide) (S-(Fe/Ni)OOH) as a superior electrocatalyst for oxygen evolution reaction (OER). It is prepared by consequent electroplating of nickel nanocone arrays (NiNCAs) on carbon cloth (CC) and stainless-steel mesh (SSM) and then formation of S-(Fe/Ni)OOH layers on them by ultrafast one-step oxidation solution-phase method in the solution of Fe3+ and sodium thiosulfate at room temperature. The derived composite material [S-(Fe/Ni)OOH@NiNCAs on SSM and CC] exhibited high electrocatalytic activity toward OER as well as good durability. The electrochemical measurements demonstrate that S-(Fe/Ni)OOH@NiNCAs-CC and S-(Fe/Ni)OOH@NiNCAs-SSM can drive the benchmark current density of 10 mA cm–2 at low overpotentials of 248 and 245 mV and current density of 100 mA cm–2 at overpotentials of 327 and 312 mV with a Tafel slope of 77 and 65 mV dec–1, respectively. Their outstanding electrocatalytic performances are benefited from porous, highly exposed active sites, accelerated mass and electron transport, and synergistic effects. The prepared composite electrodes act better than most advanced priceless catalysts and noble commercial RuO2 catalysts. This work provides an effective and efficient approach to design porous architecture catalysts on a three-dimensional substrate (SSM and CC) with high performance for energy-relevant and electrocatalysis reactions.
