A grazing incidence surface X-ray absorption fine structure (GIXAFS) study of alkanethiols adsorbed on Au, Ag, and Cu

Design and synthesis of multifunctional microencapsulated phase change materials with silver/silica double-layered shell for thermal energy storage, electrical conduction and antimicrobial effectiveness

“…As well known, thiol groups can adsorb silver ions through the cleavage of the SeH bond followed by the spontaneous formation of the SeAg bond [51]. Such a unique behavior makes the chemicals containing thiol groups achieve broad applications as chemical protocols for preparation of various multi-layered metalepolymer and metaleinorganic composites [50,52]. In this work, the introduction of thiol groups by adding MPTMS as a secondary silica precursor is the key approach in the synthesis, because these thiol groups play a role of chemical protocol to make the reduced silver nanoparticles deposit on the surface of silica shell.…”

Preparation of silver nanowires coated with TiO2 using chemical binder and their applications as photoanodes in dye sensitized solar cell

“…In particular, the existence of chemical binder between Ag core and TiO 2 shell could be confirmed by detecting the well-dispersed S element of the thiol group in 2-mercaptoethanol. Thiol groups tend to interact with silver ions by the cleavage of S-H bond and the spontaneous formation of Ag-S bond [22,23]. Also, the hydroxyl group of 2-mercaptoethanol was reacted with the hydroxyl group of surface TiO 2 through condensation reaction.…”

Adsorption behaviour of C2H5SCH3 on Ag(111) and Ag(UFP) surfaces

“…However, not so many studies have been done on the Ag surface using S K-edge NEXAFS. 1,13 To our knowledge, this is the first report on S K-edge NEXAFS data of ethylmethylsulfide (C 2 H 5 SCH 3 or EMS) on the Ag surface. The chain length of thiol has an effect on the ordering and packing of the alkane chains of the monolayer 14 and an impact on the way in which the sulfur functionality binds to the metal substrate.…”

“…Upon adsorption of sulfur-containing molecules on metal surfaces, a strong sulfur-metal interaction is established, the orientation of molecules is affected by the nature of the sulfurmetal interface 1 and charge transfer occurs from metal to molecules. 2 -4 These characteristics give rise to the unique physicochemical properties of the interface.…”
