Solar-driven interfacial evaporation provides a promising way for sustainable freshwater and energy generation. However, developing highly efficient photothermal and photocatalytic nanomaterials is challenging. Herein, sub-stoichiometric molybdenum oxide (MoO_3?x) nanoparticles are synthesized via step-by-step reduction treatment of L-cysteine under mild conditions for simultaneous photothermal conversion and photocatalytic reaction. The MoO_3-x nanoparticles of low reduction degree are decorated on hydrophilic cotton cloth to prepare MCML evaporator toward rapid water production, pollutant degradation as well as electricity generation. The obtained MCML evaporator has a strong local light-to-heat effect, which can be attributed to the excellent photothermal conversion via the local surface plasmon resonance effect in MoO_3-x nanoparticles and the low heat loss of the evaporator. Meanwhile, the rich surface area of MoO_3-x nanoparticles and the localized photothermal effect together effectively accelerate the photocatalytic degradation reaction of the antibiotic tetracycline (TC). With the benefit of these advantages, the MCML evaporator attains the superior evaporation rate of 4.14 kg m^-2 h^-1, admirable conversion efficiency of 90.7% and adequate degradation efficiency of 96.2% under 1-sun irradiation. Further, after being rationally assembled with a thermoelectric module, the hybrid device can be employed to generate 1.0 W m^-2 of electric power density. This work presents an effective complementary strategy for freshwater production and sewage treatment as well as electricity generation in remote and off-grid regions.
