“…Therefore, FeP was compounded with carbon nanotubes with high conductivity to improve its electrochemical performance. [10,11] Due to the advantages of high energy density, long cycle life, high safety and low self-discharge, lithium-ion batteries (LIBs) have become very important energy storage devices and are widely used in mobile phones, computers, power tools, electric vehicles and other electronic devices. [12,13] However, the low theoretical capacity (372 mAh g À 1 ) of existing commercially available graphite anode materials cannot meet the demand for higher power and energy density in the field of energy storage, and it is necessary to search for alternative anode materials with high capacity and long cycling stability to develop lithiumion batteries with better performance.…”

Iron phosphide (FeP) is a promising electrochemical energy storage material due to easy to obtain and high theoretical capacity. However, the intrinsic poor conductivity and the large volume change during charging and discharging process, result in a sharp decline in capacity and short cycle life for FeP. In this work, the FeP/C/CNT nanocomposite was synthesized efficiently and conveniently by one‐step solid‐phase synthesis method. Amorphous carbon‐coated FeP particles are embedded in a three‐dimensional network structure composed of highly conductive carbon nanotubes, drastically enhancing the conductivity of FeP and reducing the volume expansion during charging and discharging. In the three‐electrode system, the FeP/C/CNT composites showed good electrochemical performance, with a specific capacity as high as 124.4 mAh g−1 at 1 A g−1. Meanwhile, the constructed Ni2P@C/CNT//FeP/C/CNT asymmetric supercapacitor delivered a high energy density (70.73 Wh kg−1), power density (7.9 kW kg−1) and a long cycle life (10000 cycles). In addition, as served as an anode material in the lithium ion battery, the FeP/C/CNT composite also displayed as high as 601.8 mAh g−1of specific capacity at 0.1 A g−1 and a good cycle stability, showing superior electrochemical performance. The above work provides a promising composite material for supercapacitors and lithium ion batteries. Moreover, the solid‐state preparation methods can provide a reference for the synthesis of transition metal phosphides.

The sluggish reaction kinetics of the oxygen reduction reaction (ORR) and the formation of a biofilm on the cathode prevent efficient and stable operation of microbial fuel cells (MFCs). In this work, zeolitic imidazolate framework-derived N-doped carbon-supported CoCulayered double hydroxide nanosheets (CoCu-LDH@NC) were synthesized as a bifunctional cathode catalyst for MFCs. CoCu-LDH supported on CoO@NC induced the production of carbon nanotubes (CNTs) from the NC matrix. CNTs and CoCu-LDH nanosheets improved the atomic reaction efficiency and active area for the ORR. The high-speed electron-transfer channel was attributed to two-dimensional CoCu-LDH nanosheets and onedimensional CNTs. The catalytic activity and stability of CoO@NC were sustained through the incorporation of CoCu-LDH nanosheets. The electronic interaction of CoCu-LDH and CoO@NC enhanced the ORR catalytic activities. CoCu-LDH nanosheets generated reactive oxygen species (ROS) and Cu + , improving the antibacterial activity to prevent the growth of biofilm for MFCs. CoCu-LDH@NC demonstrated superior oxygen reduction activity with a half-wave potential of 0.84 V and an onset potential of 0.89 V. The maximum power density and operating cycle of the MFCs assembled with CoCu-LDH@NC reached 1012 mW m −2 and 170 h, respectively. This work offers guidance to enhancing the ORR catalytic activity and stability by designing antibacterial ORR catalysts.

“…40,41 In order to prevent the agglomeration of Fe x P nanoparticles and improve electrical conductivity, Fe x P nanoparticles are usually supported on carbon nanostructures to realize synergistic interaction with further boosted ORR performance. [42][43][44][45][46][47][48] These Fe x P nanoparticles modulate the electron distribution across the carbon matrix, and rendering moderate adsorption/desorption capability to the reactant/intermediate/product, along with easier activation and breakage of the O-O bond. For instance, Shan et al confirmed that the ORR performance of the three-dimensional petaloid carbon nanosheets can be dramatically improved by supporting FeP nanoparticles.…”
