As such, it is an ideal companion book to classical. A First Introduction to the Finite Element Analysis Program MSC Marc/Mentat. Download The Amazing Spiderman For Android Cracked.
We report a new and general strategy for improving the capacitive properties of TiO 2 materials for supercapacitors, involving the synthesis of hydrogenated TiO 2 nanotube arrays (NTAs). The hydrogenated TiO 2 (denoted as H–TiO 2) were obtained by calcination of anodized TiO 2 NTAs in hydrogen atmosphere in a range of temperatures between 300 to 600 °C.

The H–TiO 2 NTAs prepared at 400 °C yields the largest specific capacitance of 3.24 mF cm –2 at a scan rate of 100 mV s –1, which is 40 times higher than the capacitance obtained from air-annealed TiO 2 NTAs at the same conditions. Importantly, H–TiO 2 NTAs also show remarkable rate capability with 68% areal capacitance retained when the scan rate increase from 10 to 1000 mV s –1, as well as outstanding long-term cycling stability with only 3.1% reduction of initial specific capacitance after 10 000 cycles. The prominent electrochemical capacitive properties of H–TiO 2 are attributed to the enhanced carrier density and increased density of hydroxyl group on TiO 2 surface, as a result of hydrogenation. Furthermore, we demonstrate that H–TiO 2 NTAs is a good scaffold to support MnO 2 nanoparticles. The capacitor electrodes made by electrochemical deposition of MnO 2 nanoparticles on H–TiO 2 NTAs achieve a remarkable specific capacitance of 912 F g –1 at a scan rate of 10 mV s –1 (based on the mass of MnO 2). The ability to improve the capacitive properties of TiO 2 electrode materials should open up new opportunities for high-performance supercapacitors.
