Mesoporous Silicon/Polypyrrole Based Structures for Paranitrophenol Sensing

Elaboration of new structures based on semi-conductors and conducting polymers can procure a alternative to the development various electrochemical sensors with good sensibility. The key idea this paper is develop facile technique for detection para-nitrophenol which considered as an important toxic pollutant. In context, different mesoporous silicon modified Polypyrrole (PPy) were elaborated. hybrid have been characterized by several techniques such FTIR, SEM Contact angle measurements. addition, behavior these cyclic voltammetry was studied. results show high sensitivity sensor linearity response in large concentration interval ranging from 10−8 M the10−2M.
