Controllably Fabricated Polypyrrole Nanorods Network by Doping Tetra-Β-Carboxylate Cobalt Phthalocyanine Tetrasodium Salt for Enhanced Ammonia Sensing at Room Temperature
Morphological tuning and functional doping are important for improving the gas sensing properties of polypyrrole (PPy). Here, PPy-0.5TcCoPc nanorods with a uniformly dispersed 3-D network were prepared in one-step using the electrostatic interaction between tetra-β-carboxylate cobalt phthalocyanine tetrasodium salt (TcCoPcTs) and pyrrole (Py) molecules, in which TcCoPcTs acted both as doping molecules to modulate the morphology of PPy and as accelerators to improve the gas sensing performance. The resulting PPy-TcCoPc hybrids exhibited superior NH3-sensing properties compared to pure PPy and TcCoPc. The prepared PPy-0.5TcCoPc sensor shows an ultra-fast response/recovery time (8.1 s/370.8 s) to 50 ppm NH3, a low detection limit of 8.1 ppb, excellent gas selectivity, superior response (49.3% to 50 ppm NH3), and better stability. This results from the excellent selective affinity of NH3 for TcCoPc, the unique charge transfer between PPy and NH3, couple with the large specific surface area of the PPy-TcCoPc hybrids, which brings abundant active sites and good electron transport orbitals. The effective doping of TcCoPcTs for the modulation of PPy morphology and performance optimization strategies broadens the research of ideal gas sensor materials direction.
