A review of the role and mechanism of surfactants in the morphology control of metal nanoparticles

Abstract

Although great progress has been made in the synthesis of metal nanoparticles, their good repeatability and accurate predictability are still difficult to achieve. This difficulty can be attributed to synthetic...

Anti‐Corrosion for Reversible Zinc Anode via a Hydrophobic Interface in Aqueous Zinc Batteries

“…And these characterization results were confirmed by the digital photographs of cycled zinc foils based on different cationic surfactants as shown in Figure S3c-e, Supporting Information. These results indicated that the adsorption of surfactants with hydrophobic groups could affect the formation and growth of ZHS, [54] and were consistent with the previous analysis. That is, the DDBAC with stronger hydrophobic groups could not form a good adsorption layer to block the contact between free water with zinc foil, which leads to the decomposition of some water at the interface and induces the production of ZHS.…”

Enhanced water-resistant performance of Cu-BTC through polyvinylpyrrolidone protection and its capture ability evaluation of methylene blue

“…Polyvinylpyrrolidone (PVP) is a water-soluble polymer surfactant with hydrophilic and polar groups, 11 and its monomer is N-vinylpyrrolidone. There are two kinds of forces in PVP molecules: one is the interaction between the exposed oxygen atoms of PVP molecules and the hydrogen atoms of water molecules; the other is the interaction between the hydrogen and oxygen atoms of a water molecule and those of another water molecule.…”

Supported nanocatalysts: recent developments in microwave synthesis for application in heterogeneous catalysis

“…Some of the transition metals (Cu, Ni) are also unstable and readily oxidized in air, preventing their sustainable use. 6 Modification of transition metal nanocatalysts with functionalizing agents such as surfactants 7,8 or polymers 9 has helped to improve stability against aggregation but such modification often deteriorates the catalytic properties via changes in the electronic structure of metal nanocatalysts. 10 The alternative way proposed to overcome the aggregation and deterioration of catalytic property is the implanting or anchoring of nanocatalysts on inert low density solid supports.…”
