Under the proposed theme, Hydrogen substituted graphdiyne (HsGDY) is synthesized by a novel thermal coupling technique through the chemical vapour deposition (CVD) method. The HsGDY has similar functional properties of graphdiyne and its structural, functional properties have not been explored yet. Hence, the nanoscale characterization of the newly developed HsGDY is essential to identifying the π-conjugated butadiyne and aromatic hydrogen (Ar-H) in the 2D network. The high-resolution scanning probe microscopy (SPM) characterization and grazing incidence wide-angle X-ray scattering analysis will disclose the atomic arrangements and stacking behaviour of HsGDY. Specifically, the carbon diyne functional groups are identified with Raman spectroscopy, NMR spectroscopy and FTIR. As an output of this research, the developed material is applied to capacitive energy storage or sensing devices.

Initially, Hydrogen-substituted graphdiyne (HsGDY) is successfully synthesized over Cu₂O nanowires and the physical-chemical properties were analyzed. The electrochemical and dye removal properties of HsGDY experiments are in progress. A part of the results are presented at the 70th JSAP spring meeting 2023 on March 17-18 2023 at Shopiya University, Tokyo.
