High-yield synthesis of poly(m-phenylenediamine) hollow nanostructures by a diethanolamine-assisted method and their enhanced ability for Ag+ adsorption†
Abstract
A diethanolamine-assisted (DEA-assisted) conventional oxidation method was explored to synthesize the hollow nanostructures of poly(m-phenylenediamine) (PmPD) with a high specific surface area. The DEA concentration has a significant influence on the PmPD morphology and a possible formation mechanism has been proposed. The obtained hollow nanostructures show an excellent Ag+ adsorption ability with an adsorbance of 2359.3 mg g−1, much higher than other reported materials.
