In this study, a simple strategy was described for the synthesis of Pt-SWCNTs conductive nanocomposite by microwave heated polyol method and nanocomposite characterized by EDS, FESEM, and XRD method. The Pt nanoparticles were decorated at the surface of SWCNTs with a diameter of 22.3 nm. The synthesized nanocomposite was used for modification of the carbon paste electrode (CPE) in the presence ...

Glucose and ATP biosensors have important applications in diagnostics and research. Biosensors based on conventional materials suffer from low sensitivity and low spatial resolution. Our previous work has shown that combining single-walled carbon nanotubes (SWCNTs) with Pt nanoparticles can significantly enhance the performance of electrochemical biosensors. The immobilization of SWCNTs on bios...

Single-walled carbon nanotubes (SWCNTs) have emerged as one of the leading additives for high-capacity nanocomposite lithium ion battery electrodes due to their ability to improve electrode conductivity, current collection efficiency, and charge/discharge rate for high power applications. However, since as-grown SWCNTs possess a distribution of physical and electronic structures, it is of high ...

The gas-sensing properties of Pt-decorated carbon nanotubes (CNTs), which provide a foundation for the fabrication of sensors, have been evaluated. In this study, we calculated the gas adsorption of Pt-decorated (8,0) single-wall CNTs (Pt-SWCNTs) with SO2, H2S, and CO using GGA/PW91 method based on density functional theory. The adsorption energies and the changes in geometric and electronic st...

However, there i...

An adhesive and conductive glue was created by synergistic assembly of graphene oxide (GO), single walled carbon nanotubes (SWCNTs) and conjugate polymer PEDOT:PSS in aqueous solution. The GO–SWCNTs–PEDOT:PSS glue can be used as a binder to fabricate metal oxide nanoparticle based ultracapacitors. Since the functional nanoparticles are immersed in this conductive gel, uniform electrical and mec...

A novel conductive ceramic/graphene nanocomposite is prepared to prohibit the re-stacking of reduced graphene oxide (RGO) by wedging zirconium diboride (ZrB2) nanoparticles (NPs) into multiple layer nanosheets using a simple solvothermal method. Surprisingly, the RGO/ZrB2 nanocomposite supported Pt NPs shows very excellent catalytic activity. Its electrochemical surface area (ECSA) is up to 148...

A waste-originated one-part alkali-activated nanocomposite is introduced herein as a novel thermoelectric material. For this purpose, single-walled carbon nanotubes (SWCNTs) were utilized nanoinclusions to create an electrically conductive network within the investigated construction Thermoelectric and microstructure characteristics of SWCNT-alkali-activated nanocomposites assessed after 28 day...

There is a great need for viable alternatives to today's transparent conductive film using largely indium tin oxide. We report the fabrication of a new type of flexible transparent conductive film using silver nanowires (AgNW) and single-walled carbon nanotube (SWCNT) networks which are fully embedded in a UV curable resin substrate. The hybrid SWCNTs-AgNWs film is relatively flat so that the R...
