Here, we report a systematic investigation of the effect of experimental parameters on the structure, morphology and electrochemically active surface area of 3-D mesoporous platinum (Pt) framework. Template-assisted deposition of the mesoporous Pt framework is achieved using phytantriol-based inverse bicontinuous cubic phase of double diamond morphology (Q_II^D) with Pn3m symmetry. Platinum is deposited electrochemically using hexachloroplatinic acid solution present within the aqueous domains of the cubic phase template. Deposition conditions, particularly the deposition potentials, are shown to significantly affect the surface morphology, porosity and electrochemically active surface area of the deposited Pt framework. Furthermore, the effect of underlying substrate on the structure and morphology of the mesoporous Pt framework is also investigated.

在这里，我们报告实验参数对3-D介孔铂（Pt）骨架的结构，形态和电化学活性表面积的影响的系统研究。使用基于植物三醇的双钻石形态的反向双连续立方相实现了介孔Pt骨架的模板辅助沉积（Q _II ^D），并具有Pn3m对称性。使用存在于立方相模板水域中的六氯铂酸溶液电化学沉积铂。沉积条件，特别是沉积电位，显示出显着影响沉积的Pt骨架的表面形态，孔隙率和电化学活性表面积。此外，还研究了下面的底物对中孔Pt骨架的结构和形态的影响。
