Synthesis of Magnesium Phosphorous Trichalcogenides and Applications in Photoelectrochemical Water Splitting
Original language description
Promising applications of metal phosphorous trichalcogenides (M2P2X6 or MPX3) have been predicted in optoelectronics, photoelectrocatalysis, and water-splitting reactions, mainly due to its wide bandgap. Transition metals are widely used in the synthesis of MPX3, however, divalent cations of alkaline earth metals can also be constituents in MPX3 2D layered structures. Herein, MgPX3 (X = S, Se) are synthesized and their photoelectrochemical (PEC) activity is tested in the hydrogen evolution and oxygen evolution reaction (OER) regions under a wide range of wavelengths. MgPSe3 photoelectrode shows the best PEC performance with a response of 1.6 +/- 0.1 mA cm(-2) under 420 nm. In the light-assisted OER, a 200 mV improvement is obtained in the overpotential at 10 mA cm(-2) for MgPSe3. The better performance of MgPSe3 is consistent with its lower optical bandgap (E-g = 3.15 eV), as a result of the variation of electronegativity between selenide and sulfide.
