Raman data of molybdenum diselenide-borophene (B/MoSe2) composite

Molybdenum diselenide (MoSe2) and boron powders were purchased from Sigma Aldrich. All reagents were used without further purification.
Both bulk MoSe2 and boron have been introduced to the planetary zirconia ball mill (Fritsch Pulverisette). A series of composites with different MoSe2 to boron ratios MoSe2/B_1:10, MoSe2/B_1:1, MoSe2/B_10:1, MoSe2/B_100:1, and MoSe2/B_1000:1 with a total mass loading of 500 mg have been fabricated. Each of the prepared composites was milled using the same operating parameters with the exact number of zirconia balls (18). These processes were carried out for a total grinding time of 6 hours (to avoid overheating, the processes were conducted in a cyclic manner – 30 minutes of operation with 15-minute breaks), at a rotational speed of 450 rpm. The sample composed by MoSe2/B_1:1 manifested the best electrochemical behavior (it will be labeled as B/MoSe2), thus only this sample underwent detailed analyses.
Raman spectroscopy was conducted using an InVia Renishaw Raman microscope, employing a 532 nm excitation wavelength. Raman spectroscopy was conducted using an InVia Renishaw Raman microscope, employing a 532 nm excitation wavelength.
