abstract = {A Pt-nanoparticle-decorated 1T-MoS2 layer is designed as a
sacrificial electrocatalyst by carbothermal shock (CTS)
treatment to improve the energy efficiency and lifespan of
seawater batteries. The phase transition of MoS2 crystals
from 2H to metallic 1T─induced by the simple but potent
CTS treatment─improves the oxygen-reduction-reaction (ORR)
activity in seawater catholyte. In particular, the
MoS2-based sacrificial catalyst effectively decreases the
overpotential during charging via edge oxidation of MoS2,
enhancing the cycling stability of the seawater battery.
Furthermore, Pt nanoparticles are deposited onto CTS-MoS2
via an additional CTS treatment. The resulting specimen
exhibits a significantly low charge/discharge potential gap
of Δ0.39 V, high power density of 6.56 mW cm–2, and
remarkable cycling stability up to ∼200 cycles (∼800 h).
Thus, the novel strategy reported herein for the preparation
of Pt-decorated 1T-MoS2 by CTS treatment could facilitate
the development of efficient bifunctional electrocatalysts
for fabricating seawater batteries with long service life.},
