Laser-induced generation of hydrogen from methanol vapor

A laser-induced generation of hydrogen (LIGH) from methanol vapor by irradiation of graphene aerogel (GA) as the target with focused beam of continuous wave (CW) laser diode is reported. It was found that among the produced gases H-2, CO and CH4 were main components. The generation of gas products was observed when light emission from graphene aerogel occurred upon irradiation with laser beam. The efficiency of hydrogen generation increased with excitation power of applied laser and concentration of methanol in vapor. This process is potentially attractive for the H-2-rich and O-2 -free syngas for fuel cells. (C) 2022 The Authors. Published by Elsevier Ltd on behalf of Hydrogen Energy Publications LLC.

Automated summary

Laser-induced generation of hydrogen from methanol vapor by irradiation of graphene aerogel has been achieved, with H-2, CO, and CH4 as main components of the produced gases. The efficiency of hydrogen generation increases with excitation power of applied laser and concentration of methanol in vapor, suggesting potential application for producing H-2-rich and O-2-free syngas for fuel cells.
