“…The LIG obtained after pyrolysis was denoted LIG-CF-x, where "x" represents the laser power in watt, for further analysis. A detailed description of the pyrolysis process in the electric furnace for polymer materials can be found in other literature and is not provided herein as the exploitation of LIG-CF electrodes in HER is the main focus of this study [36,37].…”

Hierarchical porous carbon materials have received significant attention for application in catalytic water splitting because of their high efficiency, cost-effectiveness, and biocompatibility. In this study, laser-induced graphene (LIG) was fabricated on a carbon film- (CF-) type substrate for an efficient hydrogen evolution reaction (HER). The LIG-CF electrode was fabricated via laser-induced graphitization on a commercial polyimide (PI) film, followed by the pyrolysis of the LIG on the PI film (LIG-PI). During pyrolysis, the microscopic and material properties of the LIG remained intact, as verified through various characterizations. The as-prepared all-carbon electrode was then utilized as an electrode for the HER study in a 1.0 M KOH electrolyte and compared with LIG-PI and Pt electrodes. In the HER experiments, the optimized LIG-CF electrode exhibited excellent catalytic performance with zero-onset potential, and the potentials required to achieve high current densities of 10 and 20 mA/cm2 were 134 and 139 mV (vs. reversible hydrogen electrode (RHE)), respectively. The excellent performance of the LIG-CF electrode originates from the hierarchical porous structure of the LIG material, which serves as an electrochemically active site, and carbon substrate that facilitates the fast transport of ions at the electrode/electrolyte interface. Additionally, the carbon substrate shortens the transportation length of electrons which played a significant role for the enhanced performance of the LIG-CF electrode.

“…Therefore, the organic solvents must be recycled or turned into harmless products to reduce their harm to the human body and pollution to the environment. 7,8 Accordingly, before implementation of the correct use and effective handling of organic solvents, their accurate identification should be considered as the prerequisite task.…”
