Abstract:
A low-temperature sulfuric acid carbonization strategy converted pulp and paper wastewater sludge into Fe-N single-atom coordination composites for solar-driven interfacial evaporation. The evaporators achieved 96.5% average absorbance and 2.41 kg m-2 h-1 evaporation rate, while enabling effective removal of representative inorganic ions from real sludge filtrates and seawater.
