Surface-bound nanoparticles for initiating metal deposition

Surface functionalization of porous ZrO2–TiO2 membranes using γ-aminopropyltriethoxysilane in palladium electroless deposition

“…Also, Pd colloidal particles have poor adhesion to the substrate because of the absence of chemical conjunction between palladium and ceramic-based substrates. This effectively results in the decomposition of the plating bath as the Pd activation particles leach out into the solution [18]. Functionalization of the surface represents a ''soft'' pre-treatment method which does not damage the selective layer.…”

“…g-APTES introduces exposed amine groups, which can further be used to bond to Pd 2+ ions. In this way, a self-assembled monolayer was formed on the ZrO 2 -TiO 2 surface through hydrogen bonding of hydroxyl (-OH) surface functional groups and -OH groups of the gaminopropyltrihydroxysilane molecule [18].…”

Preparation of thin films comprising palladium nanoparticles by a solid–liquid interface reaction technique

“…The binding energy of Pd3d 5/2 of sample B at 335.5 eV is assignable to that of Pd(0) [52,53]. In addition to this there is a small peak at 337 eV, probably assigned to PdO, the reoxidized product of active Pd(0) by both exposure to the air and high-energy photoelectron bombardment during XP measurement [54].…”

Inkjet catalyst printing and electroless copper deposition for low-cost patterned microwave passive devices on paper

“…Such a precipitate-free printing approach eliminates problems associated with the use of noble-metal-particle-based printing. While catalyzed electroless deposition is well known, [31][32][33][34][35][36] tailoring of the palladiumbearing catalyst solution was required in the present work to allow for inkjet printing of desired patterns on the Teslin ® paper substrate. Ethanol was chosen as the solvent for the palladium chloride catalyst owing to the enhanced wetting observed for this solvent, relative to water, on Teslin ® paper.…”
