From: Innovative Strategy on Hydrogen Evolution Reaction Utilizing Activated Liquid Water

Process of preparing highly reduced hydrogen-bonded water (HRHBW) under resonant illumination on Au NPs.
The HRHBW was characterized by Raman spectra. (a) Absorption spectrum of the supported Au NPs. (b) Schematic setup for the preparation of plasmon-activated liquid water based on the LSPR effect on Au NPs under resonant illumination of an LED (λmax 530 nm). (c) Raman spectra of OH stretching of various types of water. (d) DNHBW of treated water prepared by using illuminations of fluorescent lamps and green-light LED with time.
