▎ 摘  要

Herein, we report the intercalation of t-butyl hydrazinecarboxylate on the surface of GO through the epoxide ring opening on the basal plane. Upon the intercalation, the interlayer d-spacing has increased from 0.78 to 1.21 nm and further treatment with acid, and the interlayer d-spacing was decreased from 1.21 to 0.94 nm, which was referred as Jacky-Lifting approach. DFT calculations confirm the intercalation with the energetically favorable profound interactions with GO. The as-prepared GO nanosheets were characterized by spectroscopic and microscopic techniques. This approach of tuning interlayer d-spacing between the GO nanosheets paves the way to stuff the biological sensor materials for stimuli-based biosensor applications.
