Developing transition metal nitrides with unique nanomorphology is important for many energy storage and conversion processes. Here, a facile and novel one‐step approach of growing 3D hierarchical nickel nitride (hNi3N) on Ni foam via nitrogen plasma is reported. Different from most conventional chemical synthesis, the hNi3N is obtained in much shorter growth duration (≤15 min) without any hazardous or reactive sources and oxide precursors at a moderate reaction zone temperature of ≤450 °C. Among possible multifunctionalities of the obtained nanocoral hNi3N, herein the performance in reversible lithium ion storage and electrocatalytic oxygen evolution reaction (OER) is demonstrated. The as‐obtained hNi3N delivers a considerable cycling performance and rate stability as a lithium ion battery anode, and its property can be further enhanced by coating the hNi3N surface with graphene quantum dots. The hNi3N also serves as an active OER catalyst with high activity and stability. Additionally, on the basis of controlled growth under different nitrogen plasma treatment time, the formation mechanism of the nanocoralline hNi3N is outlined for further extension to other materials. The results on time‐ and energy‐efficient nitrogen‐plasma‐based preparation of hNi3N pave the way for the development of high‐performance metal nitride electrodes for energy storage and conversion.

Recent Advances toward Achieving High‐Performance Carbon‐Fiber Materials for Supercapacitors

View full text Add to dashboard Cite

State-of-the-art energy storage devices are highly attractive for the ever-worsening energy depletion and environmental deterioration. Among various candidates, supercapacitors (SCs) have been considered among the most promising energy storage devices. As key factors for the development of SCs, the electrode materials have been widely exploited, and great achievements have been made. Among these materials, carbonfiber materials, such as carbon nanofibers (CNFs), carbon cloths (CCs), and carbon fiber papers (CFPs), are considered as promising candidates for electrodes and supports/current collectors for other electrode materials, owing to their special physical/chemical properties and structures. This Minireview aims to provide an overview of recent advances and technologies to improve the electrochemical performance of these carbon-fiber materials and their composite electrodes. We also briefly outline the current challenges and perspectives for the development of these carbon-fiber materials and carbon-fiberbased composite electrode materials.[a] Dr.

“…The C, O, S, and N elements are mainly in the form of CÀ C/C=C, CÀ O, CÀ S/C=S and pyrrolic/graphitic N, respectively ( Figure S5). [31,[33][34][35] The corresponding energy dispersive X-ray (EDX) mapping images of SNGF further illustrates the homogeneous dispersion of these heteroatoms ( The electrochemical behavior of Cu deposition on SNGF was firstly investigated by cyclic voltammetry (CV) measurement in 5 or 2 mM CuSO 4 solution containing 0.2 M H 2 SO 4 . As illustrated in Figure 1a, the deposition takes place at two stages, including two characteristic peaks at 0.1 V and À 0.12 V, the corresponding stripping peaks occur at 0.32 V and 0.14 V. The nearly overlapped redox peaks at 0.1 V and 0.32 V at different Cu 2 + concentration suggest a UPD behavior of Cu on SNGF, where deposition only occurs on the substrate surface and the deposition amount is restricted; whereas the other group of redox peaks corresponds to OPD, exhibiting larger peak area at higher Cu 2 + concentration.…”

In this study, we successfully fabricated approximately 1 nm copper clusters on sulfur and nitrogen co‐doped graphite foam (SNGF) by using an electrodeposition method. The introduction of sulfur dopants enhances the metal‐support interaction and, thus, allows the application of the underpotential deposition (UPD) technique on graphite foam. Furthermore, the strong S−Cu binding leads to the preferential formation and firm anchoring of Cu nuclei on monodispersed S sites. The controllable growth of Cu nuclei into Cu clusters is achieved by controlling the deposition amount by adjusting the electrochemical parameters. As an example, the supported Cu clusters were utilized towards oxygen reduction reaction catalysis, exhibiting a high catalytic activity and a long‐term durability. Remarkably, this strategy is promising for developing a general method to prepare other metal clusters (e. g. Ag clusters).
