QCM based mercury vapor sensor modified with polypyrrole supported palladium
Polypyrrole (PPy) nanofibers loaded with either palladium (II) acetate (PPy/Pd(O 2CCH 3) 2) or palladium (II) nitrate (PPy/Pd(NO 3) 2) were characterized by TEM, SEM, EDX, Raman and FTIR techniques prior to their use as sensing materials for QCM based mercury vapor sensors. The QCM based sensor load...
