Abstract: A polystyrene spheres (PS) coated copper foil was adopted as a template to prepare three-dimensional (3D) porous Sn film electrode. The PS colloidal spheres were synthesized through emulsion polymerization and spin-coated on copper foil. Then Tin was electrodeposited on the template foil, following by etching in tetrahydrofuran to remove PS template. The obtained Sn film has a honeycomb-like porous structure and showed improved electrochemical performance.

Abstract: The Macroporous Nanocrystalline TiO₂ Thin Film Was Prepared by Dipping-Coating Method. Polystyrene (PS) Microspheres Template Was Used as Pore-Forming Assistant and TiO₂ Sol Was Used as Precursor. the Photoelectric Characteristics of the Samples Were Studied Using Surface Photovoltage (SPV) and Photoacoustic (PA) Techniques. the Presence of a Small Amount of Residual Template Damages the Integrity of the Porous TiO₂ Film with Inverse Opal Structure, and TiO₂ May Be Restricted in Certain Application Fields as Photonic Crystals. a Small Amount of Residual Template Changes the Surface Photovoltaic Properties of the Porous TiO₂ Film, Resulting Mainly in the Broadened Scope and the Increased Intensity of SPV Response.
