Effect of nano-silver particles in bonding material on field emission properties for carbon nanotube cathodes

Titanium Dioxide-Carbon Nanotubes Composites Immobilized Ag Nanoparticles: Enhanced Photocatalytic Bacterial Inactivation and Mechanistic Study

“…On the other hand, the morphology and structure of CNTs allow them to act as specific templates for fabricating metal nanoparticle-CNTs composite [14][15]. It has been reported that Ag incorporated CNTs demonstrated high electrocatalytic activity towards hydrazine oxidation [16]. In contrast, the photocatalytic performance of Ag/TiO 2 towards 4nitrophenol reduction was also accomplished via the existence of Ag o /Ag + species at the interface of TiO 2 phases [17].…”

Characterisation of carbon nanotube pastes for field emission using their sheet resistances

“…These superior properties and their distinctive geometric feature of extremely high aspect ratios [3] makes CNTs particularly suitable for field emission applications [1] such as flat lamps [4], flat panel displays [5,6] and X-ray sources [7,8]. Many techniques-including direct CVD growth [9], dip coating [10], screen printing of CNT pastes [11], electrophoresis [12], spray coating [10] and vacuum filtration [13]-have been used to fabricate CNT field emitters, but screen printing is the favoured technique because it enables simple, low-cost and large-area processing.…”

“…Inorganic fillers are commonly added to a CNT paste to enhance its adhesion and cohesion and also to control the CNT density. Many types of inorganic fillers have been used in preparing CNT pastes, including glass frit (GF) [11], metal powders [11,14] and inorganic oxides [14,20,21]. Among these, GF, which is a well-known sealing material for electronic devices [22], is the most commonly used, probably because it is inexpensive and improves cohesion and adhesion.…”

Photoelectrocatalytic properties and bactericidal activities of silver-treated carbon nanotube/titania composites

“…The structure and morphology of CNTs enable them to serve as specific templates for preparing metal nanoparticle-CNTs nanohybrids [17][18][19][20][21][22]. The combination of these two materials (i.e., CNTs and nanoparticle) is particularly useful when integrating the properties of the two components of the hybrid materials for use in catalysis, energy storage and nanotechnology [19].…”

“…Ag ions have antibacterial effects on some microbes. In 2007, An [20] reported that Ag supported by CNTs showed high electrocatalytic activity towards hydrazine oxidation. This indicates that a relatively inexpensive Ag catalyst may be able to replace noble metal catalysts.…”
