“…[ 1,2 ] To tackle the looming energy crisis and the related problem of environmental pollution, significant efforts are being made to develop advanced energy storage and conversion systems. [ 3–5 ] Among them, direct formic acid fuel cells (DFAFCs) and direct methanol fuel cells (DMFCs) have attracted particular attention because of their high energy‐conversion efficiency, low pollutant emissions, and simplicity of fabrication as well as the ease of storage and transport of the liquid fuels involved. [ 6 ] Since the power supply capability of fuel cells is largely dependent on the properties of the electrode material used, the design and fabrication of highly efficient electrocatalysts with long lifespans and high activity with respect to the oxidation of formic acid and methanol is essential for improving the performances of DFAFCs and DMFCs.…”

Although direct formic acid fuel cells and direct methanol fuel cells have attracted a lot of interest owing to their high energy‐conversion efficiency and low pollutant emissions, their large‐scale commercial applicability is limited by lack of suitable catalysts that exhibit high activity and are cheap. Here, a synergistic morphology and defect engineering strategy for the “clean” synthesis of multiple‐twinned Pd nanoparticles on nitrogen‐doped low‐defect graphitic carbon nanosheets (Pd/NL‐GCN) without using a template or surfactant are presented. The unique grain‐boundary‐enriched multiple‐twinned Pd nanoparticles provide a large number of catalytically active sites, while the graphitic carbon frameworks with a modulated electronic structure afford high electron conductivity as well as strong poison tolerance. Consequently, the Pd/NL‐GCN hybrid shows outstanding catalytic performance with respect to the oxidation of formic acid and methanol, exhibiting a large electrochemically active surface area, high mass activity, and good long‐term durability. Moreover, the catalyst outperforms conventional Pd‐nanoparticle‐based catalysts supported on carbon black, carbon nanotubes, and graphene materials.

The exploration of a new family of flexible and high-performance electromagnetic shielding materials is of great significance to the next generation of intelligent electronic products. In this paper, we report a simple magnetic-electrospinning (MES) method for the preparation of a magnetic flexible film, γ-Fe2O3 nanoparticle-embedded polymeric nanofibers. By introducing the extra magnetic field force on γ-Fe2O3 nanoparticles within composite fibers, the critical voltage for spinning has been reduced, along with decreased fiber diameters. The MES fibers showed increased strength for the magnetic field alignment of the micro magnets, and the attraction between them assisted the increase in fiber strength. The MES fibers show modifications of the magnetic properties and electrical conductivity, thus leading to better electromagnetic shielding performance.

“…Heteroatoms (O, N or/and P) doped carbonaceous materials derived from MOFs is also reported recently. Xu et al [ 76 ] used polyacrylonitrile (PAN)/Zn(Ac) 2 (Ac: acetate) fiber as the a self-sacrificing template to grow ZIF-8@PAN layer by layer, followed by removing PAN core and produce integrated ZIF-8 tubes and finally pyrolysis of ZIF-8 tubes and immersed the carbonized product in 1 M H 2 SO 4 to obtain the nitrogen-doped carbon tubes (NCTs) ( Figure 4 c). The electrochemical measurement of NCTs, NCPs (N-doped carbon particles, by direct pyrolysis of ZIF-8 particles) and ACs in 1 M NaCl solution revealed the corresponding specific capacitances of ~290, 150 and 100 F g −1 at the current density of 1 A g −1 .…”

View full text Add to dashboard Cite

Supercapacitors (SCs), one of the most popular types of energy-storage devices, present lots of advantages, such as large power density and fast charge/discharge capability. Being the promising SCs electrode materials, metal–organic frameworks (MOFs) and their derivatives have gained ever-increasing attention due to their large specific surface area, controllable porous structure and rich diversity. Herein, the recent development of MOFs-based materials and their application in SCs as the electrode are reviewed and summarized. The preparation method, the morphology of the materials and the electrical performance of various MOFs and their derivatives (such as carbon, metal oxide/hydroxide and metal sulfide) are briefly discussed. Most of recent works concentrate on Ni-, Co- and Mn-MOFs and their composites/derivatives. Conclusions and our outlook for the researches are also given, which would be a valuable guideline for the rational design of MOFs materials for SCs in the near future.
