HKUST-1 formation in solution influenced by laser-induced plasma at the early stage

A suspension containing the raw materials of HKUST-1, which is a metal-organic framework, is irradiated by a nanosecond-pulsed laser at 532 nm to generate plasma only at the early stage (5–30 min) of the formation process. Depending on the plasma treatment conditions, HKUST-1 begins forming after th...

Description
Summary:A suspension containing the raw materials of HKUST-1, which is a metal-organic framework, is irradiated by a nanosecond-pulsed laser at 532 nm to generate plasma only at the early stage (5–30 min) of the formation process. Depending on the plasma treatment conditions, HKUST-1 begins forming after the laser-induced plasma generation is stopped. The formation of HKUST-1 can be represented by the Gualtieri model, thus suggesting that the plasma treatment only at the early stage influences the formation process by modifying the nucleation and growth rates.
