Ordered porous carbon nanomaterials have been widely employed as key elements in the field of catalysis, energy storage and fuel cells. It has also been reported that nanostructured carbonaceous materials exhibit synergetic effects for various reactions in electrochemistry when they form a composite with noble metals or semiconductor metal oxides. Recently, block copolymers (BCPs), versatile platforms for fabricating functional nanostructures with tailored arrangements and composition, have been used as carbon sources due to their ability to be directly converted into carbon, allowing it suitable for wide applications in generating well-organized, multidimensional carbon nanomaterials. Herein, we suggest simple strategies to fabricate Pt/TiO2 hybrids-embedded porous carbon thin films or nanotubes originated from BCP via anodized aluminum oxide (AAO) template wetting. Along with morphology studies, we investigate into the optical and electrocatalytic properties of Pt-TiO2/C composites. |
