Molybdenum Sulfide Quantum Dots Decorated on TiO2 for Photocatalytic Hydrogen Evolution

“…The water decomposition ability of amorphous molybdenum sulfide was first confirmed in 2011 by Merki et al and then has widely attracted the attention of scientists. − In subsequent studies, researchers inspected and verified that a-MoS 2 possesses not only extraordinary electrical conductivity but more active catalytic sites compared with c-MoS 2 , so it was widely induced into the HER. For instance, Wang et al employed amorphous MoS 2 with a monolayer structure (ML-a-MoS x ) as a catalyst for electronic HER and reached the consequence that ML-a-MoS x exhibits excellent HER performance including a smaller Tafel slope (∼46 mV dec –1 ), a small onset overpotential (∼100 mV vs RHE), and a fast turnover frequency (∼1.0 H 2 s –1 site –1 at 0.22 mV vs RHE) together with excellent stability .…”
