Facile route for synthesizing WS2/W2C nano hollow flowers and their application for hydrogen evolution reaction
Source abstract
Abstract
Recently, catalysts based on tungsten disulfide nanoflowers (WS 2 NFs) and tungsten carbide (W 2 C) materials have been intensively investigated for hydrogen evolution reaction (HER). In this study, a facile and scalable route was utilized to synthesize a nano hollow flowers catalyst based on heterostructure of WS 2 and W 2C (WS 2/W 2 C NHFs). Besides that, other structures of tungsten compounds including WS 2–WO 3 flower particles (FPs) and pure WS 2 NFs were also prepared by the similar route with slight modification, to compare the differences in their structures and HER activities. Materials properties were comprehensively studied via X-ray diffraction analysis, field emission scanning microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. Then, the HER catalytic activities of synthesized materials were also carefully studied. The results indicate that WS 2/W 2C NHFs exhibits the HER activities much better than that of prepared WS 2–WO 3 FPs and pure WS 2 NFs. The HER performance of WS 2/W 2C NHFs exhibits a low Tafel slope of about 61 mV.dec −1, an overpotential of − 280 mV at − 10 mA.cm -2, high double-layer capacitance (11.9 mF cm -2) and the superstability in acid media. This improvement is attributed to the synergistic effect of the WS 2 and W 2 C heterostructure as well as the special structure of WS 2/W 2C NHFs catalyst.
