| 英文摘要 | herein; 2d g-c3n4 nanosheets was successfully prepared by two processes: acid treatment and liquid exfoliation. the thickness of the nanosheets was nearly 4.545 nm containing similar to 13 c-n layers. the acid treatment process before liquid exfoliation for bulk g-c3n4 could effectively destroy the in-plane periodicity of the aromatic systems and made the bulk easily exfoliated. this work carefully discussed the acid treatment effect for bulk by xrd patterns, nitrogen adsorption-desorption isotherm, ft-ir spectra, and uv-vis-nir absorption spectra. moreover, the nanosheets was fabricated and transferred onto fto substrates by vacuum filtration self-assembled method to carefully investigate their optical, electrical, and photoelectrochemical properties. the thin film filtrated by 2 ml g-c3n4 nanosheets supernatant showed the best photocurrent response nearly 0.5 mu a/cm(2) and the lowest resistance of charge transfer (rct) at the interface between fto and electrolyte. the photocurrent response could be further effectively improved from nearly 0.5 to 1.8 mu a/cm(2) by the integration of cnts to promote charge separation and transfer. thus, the easy, safe, and indirect synthesis of 2d g-c3n4-based nanosheets thin films opens new possibilities for the fabrication of many energy-related devices.
