Abstract

Researchers present the synthesis and characterization of novel tantalum phosphate nanosheets by exfoliating HTaP2O8·2H2O with tetrabutylammonium hydroxide (TBAOH) and tetrabutylphosphonium hydroxide (TBPOH). The nanosheets are spin-coated to create optically homogenous thin films containing the respective counter ions. The impact of the counter ion for distinguishing VOCs is evaluated and compared to H3Sb3P2O14 and TBAxH3-xSb3 P2O14 nanosheet thin film devices. They find a clear improvement on the sensitivity toward several solvent vapors with varying polarity, resulting in a better vapor differentiation capability if organic counter ions are present.
