| Outline of Annual Research Achievements |
We developed two types of single-atom catalysts for energy-related applications based on the successful development of 3D nanoporous graphene with tunable microstructure and physicochemical properties: 3D nanoporous graphene anchored with platinum atoms for electrochemical hydrogen production; and 3D nanoporous graphene co-anchored with nickel and copper atoms for the oxygen reduction reaction and high-performance rechargeable Zinc-air batteries. Energy devices have been developed that are highly efficient, have a high power density, and are sufficiently stable. Additionally, we released a review article summarizing our systematic study on the development, characterization, and application of 3D nanoporous graphene materials.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The purpose of this research is to develop multiscale 3D nanoporous graphene materials for a variety of functional applications. We have achieved the designable production of 3D nanoporous graphenes and investigated their applications for electrochemical energy storage over the last two years. This year, we expanded our focus to electrochemical energy conversions and developed advanced electrocatalysts using the 3D nanoporous graphene materials. As a result, our research proceeds smoothly as planned.
|
| Strategy for Future Research Activity |
We intend to continue developing novel materials and innovative energy technologies based on three-dimensional nanoporous graphene. Additionally, we will investigate template-free methods for 3D graphene synthesis.
