Inducement of nanoscale Cu–BTC on nanocomposite of PPy–rGO and its performance in ammonia sensing
Source abstract
Abstract
Abstract In this study, polypyrrole-nanofiber-coated reduced graphene oxide (PPy–rGO) was decorated with nanoparticles of Cu–BTC [Cu 3(BTC)2(H2O)3 , where BTC is short for benzene-1,3,5-tricarboxylate], a typical metal–organic framework , via a hydrothermal process combined with in situ chemical polymerization . The Cu–BTC nanoparticles enabled gas capture because of their large surface area and high affinity for gases. PPy–rGO induced the formation of nanometer-sized Cu–BTC particles and provided a good platform for gas sensing because of the resulting decorated composite’s good electrical properties. The Cu–BTC/PPy–rGO nanocomposite exhibited good electrical-resistance response to NH 3 at room temperature. Compared to the PPy–rGO thin film , the Cu–BTC/PPy–rGO thin film showed enhanced NH 3-sensing properties in the form of higher sensitivity and much faster response under the same conditions. The selectivity and stability of the NH3 sensor based on the Cu–BTC/PPy–rGO nanocomposite were also investigated.
