Findings in Nanostructures Reported from Chinese Academy of Science (SnO2@TiO2 Heterojunction Nanostructures for Lithium-Ion Batteries and Self-Powered UV Photodetectors with Improved Performances)

By a News Reporter-Staff News Editor at Biotech Week -- New research on Nanostructures is the subject of a report. According to news reporting out of Beijing, People's Republic of China, by NewsRx editors, research stated, "To overcome the issue of inferior cycling stability and rate capacity for SnO2 anode materials in lithium-ion batteries, an effective strategy is explored to prepare a hybrid material consisting of rutile SnO2 nanoparticles and rutile TiO2 nanorods, considering not only the small lattice mismatch to achieve a better composited lattice structure but also their superior synergistic effect in electrochemical performances. The as-prepared SnO2@TiO2 material, directly formed on a carbon cloth as a binder-free anode, exhibits a reversible capacity of 700 mAhg(-1) after 100 discharge/charge cycles at 200 mAg(-1), as well as excellent cycling stability and rate capacity."

Our news journalists obtained a quote from the research from the Chinese Academy of Science, "After being calcinated at high temperature, the produced hollow SnO2@TiO2 hybrid microtubes were directly used to fabricate photoelectrochemical (PEC) UV detectors for future devices with self-powered function. A high photocurrent response of 0.1 mAcm(-2) was observed, together with an excellent self-powered and fast response and 'visible blind' characteristics."

According to the news editors, the research concluded: "Such a hybrid material could achieve a complementary effect in lithium-ion batteries and a superior band gap match in photovoltaic devices, and could consequently be extended to applications such as dye-sensitized solar cells and supercapacitors."
