          MnO2-FILLED MULTIWALLED CARBON NANOTUBE/POLYANILINE NANOCOMPOSITES: EFFECT OF LOADING ON THE CONDUCTION PROPERTIES AND ITS PERCOLATION THRESHOLD

          Nano01 Feb 2011

          This paper reports the synthesis and characterization of ternary nanocomposites consisting of polyaniline (PANI), multiwalled carbon nanotubes (MWCNTs) and manganese dioxide (MnO2) at different MWCNT–MnO2 loadings. The composite electrical percolation threshold is investigated as well. The in situ nanocomposites were characterized by UV-visible, Fourier transform and Raman spectroscopy, thermogravimetric analysis, field emission scanning electron microscopy, and electrical conductivity measurements. The conductivity of the nanocomposite reached up to 78.79 Scm-1 with 50 wt.% addition of MWCNT–MnO2 with good conduction stability and reversibility. The percolation threshold of this nanocomposite was achieved at 0.5 wt.%. Using the scaling law of the percolation theory, it was found that the theoretical conductivity of the nanocomposite exhibited an exponential factor, (t) of 1.38 instead of the universal t value of 2.

          Controllable Preparation of Silver Orthophosphate@Carbon Layer Core/Shell Heterostructure with Enhanced Visible Photocatalytic Properties and Stability

          Nano01 Feb 2015

          In this study, silver orthophosphate@carbon layer (Ag3PO4@C) core/shell heterostructure photocatalyst was prepared for the first time. The results showed that a uniform carbon layer was formed around the Ag3PO4. By adjusting the hydrothermal fabrication parameters, the thickness of carbon layer could be easily controlled. Furthermore, the Ag3PO4@C had remarkable light absorption in the visible region. Photocatalytic tests displayed that the Ag3PO4@C heterostructures possessed a much higher degradation rate of phenol than pure Ag3PO4 under visible light. The enhanced photocatalytic activity could be attributed to high separation efficiency of photogenerated electrons and holes based on the synergistic effect between carbon as a sensitizer and Ag3PO4. Recycle tests showed that the Ag3PO4@C core/shell heterostructures maintained high stability over several cycles. The good stability could be attributed to the protection of insoluble carbon layer on the surfaces of Ag3PO4 crystals in aqueous solution.

          In Situ Growth of MOF-Derived NaCoPO4@Carbon for Asymmetric Supercapacitive and Water Oxidation Electrocatalytic Performance

          Nano01 Dec 2019

          The increasing energy crisis promotes the study on novel electrode materials with high performance for supercapacitive storage and energy conversion. Transition metal phosphates have been reported as a potential candidate due to the unique coordination and corresponding electronic structure. Herein, we adopted a facile method for preparing NaCoPO4@C derived from a metal organic framework (MOF) as a bifunctional electrode. ZIF-67 was synthesized before a refluxing process with Na2HPO4 to form a precursor, which is transformed into the final product via calcination in different atmospheres. Specifically, the resultant NaCoPO4@C exhibits a high specific capacitance of 1178.7Fg1 at a current density of 1Ag1 for a supercapacitor. An asymmetric supercapacitor (ASC) assembled with active carbon displays a high capacitance of 163.7Fg1 at 1Ag1. In addition, as an oxygen evolution reaction (OER) catalyst, the NaCoPO4@C electrode requires only 299mV to drive a current density of 10mAcm2. These results suggest that the rational design of MOF-derived NaCoPO4@C provides a variety of practical applications in electrochemical energy conversion and storage.

          Fabrication of Biomass-Derived N, S Co-doped Carbon with Hierarchically Porous Architecture for High Performance Supercapacitor

          Nano01 Jul 2020

          Multi-element doped porous carbon materials are considered as one of the most promising electrode materials for supercapacitors due to their large specific surface area, abundant mesoporous structure, heteroatom doping and good conductivity. Herein, we propose a very simple and effective strategy to prepare nitrogen, sulfur co-doped hierarchical porous carbons (N-S-HPC) by one-step pyrolysis strategy. The effect of sole dopants as a precursor was a major factor in the transformation process. The optimized N-S-HPC-2 possesses a typical hierarchically porous framework (micropores, mesopores and macropores) with a large specific surface area (1284.87m2 g1) and N (4.63 atomic %), S (0.53 atomic %) doping. As a result, the N-S-HPC-2 exhibits excellent charge storage capacity with a high gravimetric capacitance of 360F g1 (1 A g1) in three-electrode systems and 178F g1 in two-electrode system and long-term cycling life with 87% retention after 10,000 cycles in KOH electrolyte.

          Significant Solar Thermal Conversion Properties of Ethylene Glycol Nanofluids Enhanced by Carbon Chain Nanostructures

          Nano01 Apr 2022

          Nanofluids are promising in solar harvesting and solar thermal utilization. Ethylene glycol (EG) nanofluids have the advantages of high boiling point and low volatility, and therefore are highly desired in some circumstances. In this study, the solar harvesting and solar thermal conversion properties of EG were significantly enhanced by carbon chain nanostructures (CCNSs). The prepared CCNSs/EG nanofluids showed greater optical absorption compared to EG in the wavelength range from 250nm to 1400nm. The solar weighted absorption factor (Am) of the CCNSs/EG nanofluids was 95.9% at the mass fraction of 0.05 wt.%. The enhancement was 649.2% compared to that of EG. The photothermal conversion efficiency was determined to be 97.7% and the enhancement of 83.0% was achieved. An enhancement of 1.2% in thermal conductivity was also been observed. These enhancements can be ascribed to the special architectures of the CCNSs that provide fast transfer path for the generated heat.

          The Effect of Carbon Quantum Dots on the Growth of Aspergillus Oryzae

          Nano27 Jul 2024

          Carbon quantum dots (C QDs) were synthesized using lemon juices as a precursor by hydrothermal method. The impact of C QDs on the biomass, density of spores, and morphology of Aspergillus oryzae (A. oryzae) was studied for the first time. The results revealed that C QDs had a graphite structure, and their average size was about 4.25nm. As a carbon source, C QDs were more beneficial to A. oryzae growth than glucose. It has been observed that C QDs worked as an activator to improve the yield of A. oryzae, and the biomass and density of spores of A. oryzae cultured with 15mg C QDs were about 1.46 and 2.00 times higher than that in control medium (without C QDs). Our work can give a new idea for improving the yield of A. oryzae or microorganisms and satisfy industrial requirements.
