Achieving stable and efficient solar-driven evaporation of high-salinity brine is highly desirable while challenging because of salt inevitably blocking the evaporator surface during vapor generation. One of the effective resolvents is to construct macropores to ensure sufficient diffusion and convection of concentrated salt back into the bulk water. Herein, inspired by the interconnected pores of the balsa wood, superhydrophilic porous TiC/C absorber (SPTCA) with macro-/micro-/nano-pores network is successfully built by carbothermic reduction. The macropores channel plays the role of water transport, steam overflow, and salt ion diffusion backflow. The micro-/nano-pores channel enables broadband light absorption and keeps the moisture in a small range to achieve high-efficiency evaporation. With this rational design, the evaporator alloys for a stabilized evaporation of 1.78 kg/m² h from simulated seawater for over 100 days and 1.75 kg/m² h from high-salinity brine (15 wt.% NaCl) for over 50 days under 1 sun irradiation. The SPTCA provides a promising avenue for architecting the multiscale-pores network for solar desalination of high-salinity brine.

实现高盐度盐水的稳定和高效的太阳能驱动蒸发是非常可取的，但也具有挑战性，因为在蒸汽产生过程中盐不可避免地会阻塞蒸发器表面。一种有效的解决方案是构建大孔以确保浓盐充分扩散和对流回到本体水中。在此，受轻木互连孔隙的启发，通过碳热还原成功构建了具有大孔/微孔/纳米孔网络的超亲水多孔 TiC/C 吸收剂（SPTCA）。大孔通道起到输水、蒸汽溢流、盐离子扩散回流的作用。微/纳米孔通道可实现宽带光吸收，并将水分保持在小范围内，实现高效蒸发。有了这个理性的设计，^{模拟海水2}小时超过 100 天，1.75 kg/m ²小时，高盐度盐水（15 wt.% NaCl）在 1 次太阳照射下超过 50 天。SPTCA 为构建用于太阳能淡化高盐度盐水的多尺度孔隙网络提供了一条有前景的途径。
