Summary Nitrogen‐doped porous carbon (NPC@ZIF‐11) and boron‐NPC (BNPC@ZIF‐11) materials were synthesized by pyrolysis methods, and structural characterization of the compounds was carried out by scanning electron microscopy, transmission electron microscopy, Fourier‐transform infrared spectroscopy, X‐ray diffraction, Brunauer–Elmet–Teller technique, Raman spectroscopy, and inductively coupled plasma‐mass spectrometry techniques. The ZIF‐11 was converted to the NPC@ZIF11 by pyrolysis. BNPC@ZIF‐11 was fabricated from NPC@ZIF‐11 by pyrolysis in the presence of phenylboronic acid. The fabric supercapacitor, sandwich‐type supercapacitor, and Li‐ion battery performances of NPC@ZIF‐11 and BNPC@ZIF‐11 were investigated. The capacity of the Li‐ion cell was found as 720 mAh g−1 for the first cycle, and it was decreased to 250 mAh g−1 after 100 cycles. The capacitance values of the cylindrical devices were 92 F g−1 and 115.6 F g−1, for C1 and C4000 in KOH electrolytes. The BNPC@ZIF‐11 was used as an electrode material on cotton fabric, and the highest obtained capacitance was 72.8 mF for 0.1 mA, which is a promising result for wearable energy storage materials.

Magnetic porous carbon composite was synthesized from zeolitic imidazolate framework (ZIF‐12) and used as a support material to fabricate CoPd nanoparticles decorated NPC@ZIF‐12 nanocatalyst. The structure of CoPd@NPC@ZIF‐12 has been characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray diffraction (XRD), Raman, Brunauer–Emmett–Teller (BET), X‐ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), and inductively coupled plasma mass spectrometry (ICP‐MS) techniques. The catalytic reduction reaction of nitrophenols (NP) to aminophenols (AP) was successfully achieved by CoPd@NPC@ZIF‐12 nanocatalyst. When the catalytic performance of the catalyst was compared with other reported catalysts, the performance of the catalyst and reusability was found much better. This better catalytic activity of the CoPd@NPC@ZIF‐12 nanocatalyst may be attributed to facilitating the mass transfer of the nitro compound and the wettability of catalyst caused by the high nitrogen content of the carbon matrix and to the synergistic effect of Co and Pd nanoparticles. The CoPd@NPC@ZIF‐12 nanocatalyst showed perfect catalytic activity in the reduction of 4‐nitrophenol (4‐NP), 3‐nitrophenol (3‐NP), and 2,4‐nitrophenol (2,4‐DNP) reactions with high turnover frequency (TOF) values of 1679, 2687, and 1014 h−1, respectively. The reusability experiments of the CoPd@NPC@ZIF‐12 nanocatalyst showed that the catalytic activity of the CoPd@NPC@ZIF‐12 nanocatalyst was almost retained after 10 consecutive reaction runs. The SEM, XRD, and FTIR analyses of the 10 times used CoPd@NPC@ZIF‐12 nanocatalyst showed that there were limited changes in the structure of the CoPd@NPC@ZIF‐12 nanocatalyst. This highly active, magnetically separable, and recyclable CoPd@NPC@ZIF‐12 catalyst exhibits better catalytic activity than commercial Pd/C catalysts.

Metal‐organic frameworks (MOFs) have been important electrochemical energy storage (EES) materials because of their rich species, large specific surface area, high porosity and rich active sites. Nevertheless, the poor conductivity, low mechanical and electrochemical stability of pristine MOFs have hindered their further applications. Although single component MOF derivatives have higher conductivity, self‐aggregation often occurs during preparation. Composite design can overcome the shortcomings of MOFs and derivatives and create synergistic effects, resulting in improved electrochemical properties for EES. In this review, recent applications of MOF composites and derivatives as electrodes in different types of batteries and supercapacitors are critically discussed. The advantages, challenges, and future perspectives of MOF composites and derivatives have been given. This review may guide the development of high‐performance MOF composites and derivatives in the field of EES.
