Abstract
The direct growth of catalysts on three-dimensional self-supporting substrates is the trend of choice for the industrialization of water splitting. Although a large number of catalysts have been reported every year, there are only a handful of self-supporting substrates available for researchers to choose from. In this work, we introduce femtosecond laser micro-nano processing technology to fabricate a novel acid-resistant silicon substrate with super-hydrophilic and super-aerophobic properties (fs-Si). Rose-shaped Co0.67Ni0.33P micro-flowers grown on fs-Si (Co0.67Ni0.33P/fs-Si) can be used as an efficient and stable hydrogen evolution reaction (HER) electrocatalyst in acidic solution. XPS analysis and DFT calculation showed that the synergistic effect between CoNiP and fs-Si resulted in the required electronic states, enhanced the activity, endowed Pt-like HER performance. This work provides a new idea for expanding the variety of self-supported substrates and synthesizing highly efficient acidic HER electrodes.
