New Aromatic Hydrocarbons Data Have Been Reported by Investigators at JiaoTong University

June 6, 2014

By a News Reporter-Staff News Editor at Science Letter -- A new study on Aromatic Hydrocarbons is now available. According to news originating from Nanchang, People's Republic of China, by NewsRx correspondents, research stated, "Au/La2O3 nanomaterials were prepared through calcining Au-modified La(OH)(3) precursors. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffractometry (XRD) were employed to characterize the as-prepared samples."

Our news journalists obtained a quote from the research from JiaoTong University, "Benzene, a common volatile organic compound, was selected as a model to investigate the cataluminescence (CTL)-sensing properties of the Au/La2O3 nanomaterials. Results indicated that the as-prepared Au/La2O3 exhibited outstanding CTL properties such as stable intensity, high signal-to-noise values, and short response and recovery times. Under optimized conditions, the benzene assay exhibited a broad linear range of 1-4000 ppm, with a limit of detection of 0.7 ppm, which was below the standard permitted concentrations. Furthermore, the gas sensor system showed outstanding selectivity for benzene compared with seven other types of common volatile organic compounds (VOCs)."

According to the news editors, the research concluded: "The proposed gas sensor showed good characteristics with high selectivity, fast response time and long lifetime, which suggested the promising application of the Au/La2O3 nanomaterials as a novel highly efficient CTL-sensing material."
