Gram-scale synthesis of porous three-dimensional carbon nanosheets for high efficiency clean water production
BSTRACTThree-dimensional carbon nanosheets (3D-CNS) with excellent photothermal conversion (PTC) efficiency and solar evaporation performance were synthesized via a facile
versatile
and gram-scale co-precipitation carbonization strategy. Here
water-soluble biomass (protein) and inorganic salt (K
2
SO
4
) were co-precipitated in organic phase. The co-precipitation was then carbonized. The 3D-CNS constituted of thin
transparent
wrinkled
and interconnected nanosheets was yielded by the removal of soft template. The resulted material displayed an unprecedented PTC efficiency (
h
= 79.76%) at a power density of 1.5 W cm
−2
. The carbon-based photothermal membrane based on 3D-CNS was easily obtained by suction filtration
and exhibited excellent evaporation performance (89.55 ± 0.56%).
