New Nanocomposites Study Findings Have Been Reported by Researchers at Karlsruhe Institute of Technology

June 13, 2014

By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Nanocomposites have been presented. According to news reporting originating in Karlsruhe, Germany, by NewsRx journalists, research stated, "Pd@SnO2 and SnO2@Pd core@shell nanocomposites are prepared via a microemulsion approach. Both nanocomposites exhibit high-surface, porous matrices of SnO2 shells (>150 m(2)g(-1)) with very small SnO2 crystallites (

The news reporters obtained a quote from the research from the Karlsruhe Institute of Technology, "Although similar by first sight, Pd@SnO2 and SnO2@Pd are significantly different in view of their structure with Pd inside or outside the SnO2 shell and in view of their sensor performance. As SMOX-based sensors (SMOX: semiconducting metal oxide), both nanocomposites show a very good sensor performance for the detection of CO and H-2. Especially, the Pd@SnO2 core@shell nanocomposite is unique and shows a fast response time (tau(90) < 30 s) and a very good response at low temperature (

According to the news reporters, the research concluded: "Under these conditions, even commercial sensors (Figaro TGS 2442, Applied Sensor MLC, E2V MICS 5521) are outperformed."
