ChemInform Abstract: Synthesis and Enhanced Electrochemical Catalytic Performance of Monolayer WS2(1‐x)Se2x with a Tunable Band Gap.

Abstract Monolayer WS 2(1‐x) Se 2x (x = 0.18, 0.3, 0.43) is are prepared by simultaneous sulfurization and selenation of WO 3 deposited by CVD with 5% H 2 /Ar as the carrier gas on a Si/SiO 2 (300 nm) substrate in a two‐zone heater (830 °C at the WO 3 deposition site, 300 °C at the S/Se site, 15 min).
