Abstract The metal oxides/graphene composites are one of the most promising supercapacitors (SCs) electrode materials. However, rational synthesis such materials with controllable conductivity and electrochemical activity is topical challenge for high‐performance SCs. Here, Co 3 O 4 /graphene composite taken as a typical example develops novel/universal one‐step laser irradiation method that overcomes all these challenges obtains oxygen‐vacancy abundant ultrafine nanoparticles/graphene...
Self‐assembled α‐Fe 2 O 3 mesocrystals/graphene nanohybrids have been successfully synthesized and a unique mesocrystal porous structure, large specific surface area, high conductivity. Mesocrystal structures recently attracted unparalleled attention owing to their promising application in energy storage as electrochemical capacitors. However, mesocrystal/graphene growth mechanism not clearly investigated. Here we show facile fabrication of short rod‐like by self‐assembly FeOOH nanorods the...
Nitrogen-doped graphene-ultrathin MnO2 sheet composites (NGMCs) were prepared through a one-step hydrothermal method at low temperature (120 °C). Ultrathin sheets well-dispersed and tightly anchored on graphene sheets, which doped with nitrogen simultaneously. NGMCs electrode exhibited enhanced capacitive performances relative to those of undoped (GMCs). As the current density increased from 0.2 2 A/g, capacitance still retained ~74.9%, was considerablely higher than that GMCs (27%)....
The heterojunction of g-C3N4/BiOI was uniformly immobilized on electrospun polyacrylonitrile (PAN) nanofibers via a facile in situ synthesis at room temperature. X-ray photoelectron spectra showed that both the C and N 1s peaks PAN/g-C3N4/BiOI shifted to higher binding energies as compared those PAN/g-C3N4 suggesting electron transfer from g-C3N4 BiOI during formation heterojunctions. enhanced photocurrent densities significant decrease photoluminescence intensity confirmed effective charge...
Hydrogenated TiO2 (H-TiO2) are considered one of the most promising materials for supercapacitors given its low-cost, high conductivity, and enhanced electrochemical activity. However, performances H-TiO2 due to lacking suitable structures is unsatisfactory, thus how design energetic H-TiO2-based electrode architectures still remains a great challenge. Herein, covalently coupled ultrafine nanocrystals/nitrogen-doped graphene (H-TiO2/NG) hybrid were developed through simple hydrothermal route...
Abstract In the past decades, pseudocapacitive materials (PCMs) for electrochemical energy storage have drawn enthusiastic attention from researchers, owing to their virtue of larger Faradaic capacitance facilitating enhanced densities compared electric double‐layer capacitive materials. To maximize properties without sacrificing power densities, novel design and fine fabrication innovative PCMs with rational micro‐structures become significant importance. Typically, enormous efforts been...
Porous α-Fe2O3/graphene composites (S-PIGCs) have been synthesized by a simple hydrothermal method combined with slow annealing route. The S-PIGCs as supercapacitors electrode material exhibit an ultrahigh specific capacitance of 343.7 F g–1 at current density 3 A g–1, good rate capability, and excellent cycling stability. enhanced electrochemical performances are attributed to the contribution from optimally architecture porous α-Fe2O3, result annealing, extraordinary electrical...
Crumpled nitrogen-doped graphene–ultrafine Mn3O4 nanohybrids (CNGMNs) were synthesized through a one-step strategy under hydrothermal conditions for promising application as supercapacitor materials. Doping of N atoms in the lattice graphene and anchoring nanoparticles on sheets achieved concomitantly during process assistance aniline. The specific capacitance this nanostructured hybrid was nearly six times that counterpart. Additionally, enhanced rate capability cycling stability (∼98.7%...
Flexible photocatalysts stand out from numerous because of their foldable, reusable, and mechanically stable properties.
