Superaerophobic Hydrogels Application for Enhancement of Hydrogen Production Performances of Electrochemical and Photoelectrochemical Reaction |
| 초록 |
The efficient removal of gas bubbles in (photo)electrochemical gas evolution reaction is very important in terms of electrochemical active surface area. Recently, many researchers have been working on methods to control the microstructure of electrodes, but most of these approaches have limitations such as material specificity and lab scale. We report a simple strategy that addresses existing limitations by depositing hydrogels to accomplish superaerophobicity to desired electrode surfaces. In this study, we deposited a M13 bacteriophage template transparent hydrogel onto electrochemical and photochemical electrodes. The deposited hydrogel overlayer facilitated the elimination of produced hydrogen bubbles and significantly improved the electrodes’ performances by minimizing the concentration overpotential and maintaining high catalytic activity. We suggest that this study can contribute to the practical application of various types of (photo)electrochemical gas-evolution reactions. |
