Layer by Layer Self-Assembly of Thin Films of Metal Hexacyanoferrate Multilayers

Abstract

A general methodology to prepare redox active inorganic multilayers consisting of copper hexacyanoferrate layers formed by successive self-assembly and solution epitaxy is described. The layers are separated by a mercaptopropionic acid spacer.

Solution electrospinning of polypropylene-based fibers and their application in catalysis

“…There are various types of substrates using for the metal nanoparticle encapsulation as metal oxides [14,17], organically modified silicates [18], thin films [19,20], fibers [13], and dendrimers [21]. Considering these substrate types, fiber formed materials display more efficient catalytic performance as compared to the others because of their high surface area, low resistance to flow of gas and liquids, flexible structure, and safer operation conditions [22].…”

Electrochemistry with Nanoparticles

“…The possibility of constructing electrochemical interfaces with tunable kinetic barriers has recently been reported [42]. A planar gold electrode is modified with a hydrolyzed mercaptosilane sol to yield a surface with high blocking properties.…”

An Amperometric Sensor for Hydrogen Peroxide Based on a (3‐Mercaptopropyl)trimethoxysilane Self‐Assembled Layer Containing Hydrazine

“…Various techniques such as physical adsorption, covalent attachment, cross linking, electrostatic binding, etc., have been used to immobilize catalysts over the well ordered thiol layers formed on metal surface, with a high degree of control over the molecular architecture of the recognition interface [4,5]. Recently, using thiolated silicon alcoxides for designing three-dimensional silica gel interfacial structure via direct coupling of sol-gel and SAM technologies was reported [6,7]. The formation of silica gel confined interfaces based on the coupling of sol-gel and SAM technologies may be applied to immobilize a catalyst.…”

“…The quality of the bleached product is strongly dependent on the H 2 O 2 concentration. In addition, sensors with good stability and sensitivity at an alkaline medium are necessary for the monitoring of H 2 O 2 continuously to improve the dye quality [7]. Moreover, the interference from the reducible metal ions in aqueous media can be eliminated as most of them can be precipitated as their hydroxides at this pH conditions.…”
