Ultraviolet-visible spectroscopy (UV-Vis) data of molybdenum disulfide-borophene (B/MoS2) composite

The samples description: 
MoS2 - commercial molybdenum disulfide (Sigma-Aldrich). The main manuscript describes the results obtained with commercial MoS2 and an optimal composite composition of MoS2:B = 500:1, which was labeled as B/MoS2. In detail, the preparation of borophene-enriched MoS2 catalysts was performed using a planetary zirconia ball mill, equipped with 18 zirconia balls (Fritsch Pulverisette). The milling cycle lasted 6 h, with precautions taken to prevent overheating by employing 30 min milling periods followed by 15 min cooling breaks. The operational parameters were set at 450 rpm, with a total mass loading of 500 mg for the molybdenum disulfide (Sigma-Aldrich) and boron (Sigma-Aldrich) powders.
The optical properties of pristine MoS2 and B/MoS­2 were investigated using UV-Vis spectroscopy.Optical absorption spectra were obtained using a JASCO V-770 UV-Vis spectrophotometer in diffuse reflectance mode (DRS), with barium sulfate (BaSO4) as the reference standard.
