A graphene assembled porous fiber-based Janus membrane for highly effective solar steam generation

Owing to the shortage of clean water as the global problem, the exploration of photothermal substances with high performance solar steam generation for sustainable water purification is essential and urgent. Herein, we demonstrate the assembly of two-dimensional graphene into one-dimensional rough, loose, and porous fibers and further use the assembled fibers to fabricate Janus membrane evaporator. The specific configuration guarantees an...
