“…ZIF-8 was obtained by a simple hydrothermal method at low temperature and underwent pyrolysis in H 2 /Ar atmosphere to form N-doped porous carbon with dispersed zinc nanoparticles. Based on the potential difference between redox couples of Zn 2+ /Zn (− 0.76 V vs. SHE) and Bi 3+ /Bi (0.31 V) [ 45 ], bismuth nanoparticles were anchored on the carbon matrix through a replacement reaction. The carbon matrix afforded an electronically conductive network and served as support to restrain the aggregation of bismuth nanoparticles [ 46 ].…”

A novel bismuth–carbon composite, in which bismuth nanoparticles were anchored in a nitrogen-doped carbon matrix (Bi@NC), is proposed as anode for high volumetric energy density lithium ion batteries (LIBs). Bi@NC composite was synthesized via carbonization of Zn-containing zeolitic imidazolate (ZIF-8) and replacement of Zn with Bi, resulting in the N-doped carbon that was hierarchically porous and anchored with Bi nanoparticles. The matrix provides a highly electronic conductive network that facilitates the lithiation/delithiation of Bi. Additionally, it restrains aggregation of Bi nanoparticles and serves as a buffer layer to alleviate the mechanical strain of Bi nanoparticles upon Li insertion/extraction. With these contributions, Bi@NC exhibits excellent cycling stability and rate capacity compared to bare Bi nanoparticles or their simple composites with carbon. This study provides a new approach for fabricating high volumetric energy density LIBs.Electronic supplementary materialThe online version of this article (10.1007/s40820-018-0209-1) contains supplementary material, which is available to authorized users.

“…[8] Conventionally, the electrochemical deposition method was applied; only few studies reported the chemical method for the fabrication of Bi nanostructure. [9] In this study, the bismuth nanodendrite was succesfully obtained by chronopotentiometric method. The electrodeposition condition of the BiNDs was carefully examined.…”

In this study, bismuth nanodendrites (BiNDs) were fabricated on glassy carbon electrode by chronopotentiometric method. The hierarchical structure and high population matrix of BiNDs provides high surface active area to enhance the electrochemical signals of measured Cd2+ and Pb2+ ions. The developed bismuth nanodendritic structure was well‐observed and characterzied by scanning electron microscopy (SEM). Electrochemical behaviours of developed BiNDs electrodes were studied by the cyclic voltammetric (CV) method. The fabrication conditions for BiNDs such as the applied current and deposition time were optimized as ‐10 mA and 90 s, respectively. Under this optimized condition, the highest peaks of Cd2+ and Pb2+ ions at concentration of 20 ppb were obtained. The Cd2+ and Pb2+ signals acquired by BiNDs are almost three times greater than that measured by the Bi film electrode.

“…Currently, hydrophobic and oleophilic material is relatively promising in oil-water separation because of its intrinsic different wettability of oil and water [7,8]. Based on this, numerous hydrophobic porous materials synthesis routes (including dip-coating [9,10], vapor deposition [11][12][13], electrochemical deposition [14][15][16], in-situ synthesis [17][18][19][20][21], electrospinning [22,23]) have been reported to fabricate superhydrophobic and superoleophilic surface. Besides, spraying technique is a one-step process to obtain a special wetting coating occupying appropriate surface roughness and chemical composition [24,25].…”

Foam-based material with unique wettability is one of the promising materials for developing oil-spill cleanup, benefiting from its intrinsic interconnected three-dimensional skeleton, oil permeation and water repellency. However, obtaining a foam-based material capable of in situ separating oil spills, especially with superhydrophobic durability and simple recycling mode, remains challenging. Herein, we reported a one-step spraying approach to fabricate fluorinated ethylene propylene (FEP)/ polyvinylidene fluoride (PVDF)/ ultrafine polyurethane (UPU)/ hydrophobic nanosilica (HSiO 2)-decorated nickel foam coating with a static water contact angle (WCA) of 157±1.5˚ and a static oil contact angle (OCA) of 0˚. Owing to the foldability of the coated nickel foam, we established a continuous in-situ collection apparatus by external pumping on 3D nickel foam box. UPU addition endowed the resultant 3D nickel foam with excellent interfacial adhesion. After 7 days of continuous oil-water experiment that simulated cleanup oil-spill, the static WCA of the 3D nickel foam with 10 wt% UPU was still above 130˚. Notablely, after heat treatment at 240 ℃, the fabricated 3D nickel foam coating could be refreshed from the damaged surface to superhydrophobic.
