X-ray photoelectron spectroscopy (XPS) data of molybdenum disulfide-borophene (B/MoS2) composite

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.
X-ray Photoelectron Spectroscopy (XPS) was employed to investigate the chemical composition and bonding environment of pristine MoS2 and B/MoS2. X-ray Photoelectron Spectroscopy (XPS) measurements were performed using a Prevac system equipped with a Scienta SES 2002 electron energy analyzer, employing MgKα radiation.
