Article Synopsis
- Mesoporous noble metals are promising for applications in electrocatalysis, photocatalysis, and optoelectronics due to their high active site exposure and large surface area.
- Despite the interest, techniques for patterning mesoporous metals are still limited when compared to metal oxides and silica.
- This study successfully demonstrates the creation of patterned mesoporous gold films on photolithographically prepared substrates, along with findings that indicate these patterned films possess enhanced electrochemical properties over their non-patterned counterparts.
Stable polymeric micelles have been demonstrated to serve as suitable templates for creating mesoporous metals. Herein, we report the utilization of a core-shell-corona type triblock copolymer of poly(styrene--2-vinylpyridine--ethylene oxide) and H₂PtCl₆·H₂O to synthesize large-sized mesoporous Pt particles. After formation of micelles with metal ions, the reduction process has been carried out by vapor infiltration of a reducing agent, 4-(Dimethylamino)benzaldehyde.
