The Many Applications of Electrostatic Adsorption for the Preparation of Supported Metal Nanoparticles
Abstract
A simple, scientific method to prepare supported metal nanoparticles was proposed almost 50 years ago, which utilizes the protonation-deprotonation chemistry of the nascent hydroxyl groups that populate typical support surfaces. In aqueous solution, these can be protonated and so positively charged in the pH range below the point of zero charge (PZC) of the support, and deprotonated and negatively charged above the support PZC. An oppositely charged metal complex in the impregnating solution will experience a strong electrostatic attraction to the surface and will be firmly anchored during drying. The metal nanoparticles produced after thermochemical conversion of the dried precursor are typically small (
