Facile “scratching” method with common metal objects to generate large-scale catalyst patterns used for growth of single-walled carbon nanotubes
A facile “scratching” method to pattern a catalyst with commonly used metal objects, such as blade, pen cover, tweezers, watchband, knife, key, clamp, and coin, was developed. The single-walled carbon nanotube (SWCNT) ...
One-step growth of graphene–carbon nanotube hybrid materials by chemical vapor deposition
Graphene–carbon nanotube (CNT) hybrid materials were synthesized by simple one-step chemical vapor deposition (CVD) using ethanol as precursor. On a copper foil decorated with silicon nanparticles (Si NPs), a graphene film ...
Graphene oxide as a carbon source for controlled growth of carbon nanowires
A simple methodfor the controlled growth of novel reduced graphene oxide/carbon nanowire (rGO/CNW) composites is developed. Without any additional carbon precursor, the graphene oxide itself serves as the only carbon source. ...
Controlled assembly of gold nanoparticles and graphene oxide sheets on dip pen nanolithography-generated templates
The ability to organize nanomaterials, e.g., Au nanoparticles (NPs) and graphene oxide (GO) sheets, into ordered structures with high accuracy and resolution on a substrate is crucially important for fundamental studies ...
Preparation of Cobalt Sulfide Nanoparticle-Decorated Nitrogen and Sulfur Co-Doped Reduced Graphene Oxide Aerogel Used as a Highly Efficient Electrocatalyst for Oxygen Reduction Reaction
A novel 3D cobalt sulfide (CoS) nanoparticle-decorated nitrogen and sulfur co-doped reduced graphene oxide aerogel (NSGA), referred to as CoS/NSGA, is prepared via three sequential processes, i.e., freeze-drying, annealing, ...
Facile “Needle-Scratching” method for fast catalyst patterns used for large-scale growth of densely aligned single-walled carbon-nanotube arrays
Scratching the surface: a simple needle-scratching method (NSM) generates large-area catalyst patterns on solid substrates for the growth of densely aligned single-walled carbon-nanotube (SWCNT) arrays by chemical vapor ...
Controlled growth of nano-and bio-arrays on patterned substrates
Bio-and nano-material arrays have attracted significant attention due to their importance in a number of research and application fields, such as biology, sensors, devices, etc. How to generate these arrays in a controlled ...
All-carbon electronic devices fabricated by directly grown single-walled carbon nanotubes on reduced graphene oxide electrodes
A simple method for fabrication of all carbon CNT-rGO devices was developed, where the individual long-aligned SWCNT directly grew by CVD to connect with rGO electrodes scratched by non-metal objects.
