Activated carbon was fabricated by using phenolic resin as carbon source, tween-80 as organic template, KOH as activator. The samples were analyzed by N2 adsorption, scanning electron microscopy (SEM). Cyclic voltammetry and galvanostatic charge-discharge were used to characterize the electrochemical performance of the samples. The results showed that specific surface area of the prepared sample was 1935.99 m2/g, pore size was mainly in the range of 1.0～4.0 nm and showed typical capacitance characteristics in cyclic voltammetry. At a current density of 15mA/cm2, a specific capacitance of 246.18F/g was achieved and the resistance was 1.11Ω. Supercapacitors based on the sample had low ESR and excellent power property.

Core-shell SnO 2 @ZnO composite nanospheres were successfully prepared by using carbon spheres as sacrificial templates via a facile three-step procedure including a hydrothermal method. In contrast, pristine SnO 2 nanospheres and ZnO nanoparticles were obtained through a similar method with different steps, respectively. The composition and structures of the as-synthesized samples were confirmed by a series of characterization procedures. The obtained composite materials exhibited the special core-inhollow-shell structure at the nanometer level. And as potential sensing materials, the obtained coreshell SnO 2 @ZnO composite nanomaterials demonstrated better gas sensing properties to ethanol including higher response, better selectivity, faster response and favorable repeatability, which may be related to the special core-in-hollow-shell structure with a porous surface and the hetero-contact between two different metal oxide semiconductors.

In/Pd-doped SnO2 is synthesized via a sol-gel method and coated on a silicon substrate with Pt electrodes to fabricate a micro-structure sensor. The sensor can be used to detect CO down to 1 ppm (the sensitivity is about 3), and the response time and recovery time are about 5 and 15 s, respectively. Excellent selectivity is also found based on our sensor. These results demonstrate a promising approach to fabricate high-performance CO sensors with high sensitivity and quick response.
