Abstract In the present study, we report a novel dual template approach to prepare N-doped carbon microspheres with highly accessible mesopores and honeycombed interior structure via taking advantage of the surfactant-directed assembly within Pickering emulsion droplets. The resultant carbon microspheres possess ordered mesopores (~7 nm), uniform macropores (~1 μm), a high N content (~7.8 wt%) and a high surface area (~535 m2 g−1). The sizes of macropores can be easily manipulated by adjusting the amount of F127. Moreover, the microspheres show enhanced performance as supports for catalytic hydrogenation.

双模板合成具有蜂窝状内部结构的功能性介孔碳微球

摘要 在本研究中，我们报告了一种新的双模板方法，通过利用 Pickering 乳液液滴内的表面活性剂定向组装来制备具有高度可接近的介孔和蜂窝状内部结构的 N 掺杂碳微球。所得碳微球具有有序的中孔 (~7 nm)、均匀的大孔 (~1 μm)、高 N 含量 (~7.8 wt%) 和高表面积 (~535 m2 g-1)。通过调整 F127 的量可以很容易地控制大孔的大小。此外，微球作为催化氢化的载体表现出增强的性能。
