One-step Synthesis Pd@Pt Core-Shell Concave Cube by Facile Reduction Control toward formic acid oxidation reaction. |
| 초록 |
The core-shell Pd@Pt nanocubes were successfully designed as concave structure by a galvanic replacement, one-step process. In this study, we chose the ascorbic acid and citric acid as the different strength reduction to facile control the Pd@Pt crystal growth. Firstly, the Pd nanocube formed using ascorbic acid as stronger reducing agent with accuracy control amount. In general, the different intensities reducing agent ascorbic acid and citric acid are the key-points to kinetic control the concave structure formed and the Br- play the major role to enhance the galvanic replacement reaction between Pt(II)Cl42-and Pd. In addition, the concave cubic Pd@Pt nanocrystal exhibited higher electrochemical performance compare to commercial Pt electrocatalyst toward formic acid oxidation reaction. |
