Synthesis and characterization of anatase TiO2 nanosheet arrays on FTO substrate
چکیده انگلیسی

We have exploited a green approach to prepare layered titanate Na2-xHxTi2O5
• H2O nanosheet arrays on FTO substrate by hydrothermal hydrolysis of titanium(IV) isopropoxide (TTIP) with aids of Na2EDTA and TEOA as co-coordination agents, which were then treated by HNO3 to replace Na+ by H+, followed by a calcination at 450 °C to topotactically transform into anatase TiO2 nanosheet arrays. SEM, TEM, XRD, and Raman spectroscopy have been employed to characterize the nanosheet films. The TiO2 nanosheet arrays were further applied as electron transport materials of CH3NH3PbI3 perovskite solar cells, achieving power conversion efficiency of 6.99%.

Well-defined anatase TiO2 nanosheet arrays have been formed on FTO substrate via a green hydrothermal approach, and have been employed as building blocks of perovskite solar cells.Figure optionsDownload as PowerPoint slide
