摘要

The growing global water crisis necessitates innovative solutions that are both cost-effective and environmentally sustainable. Atmospheric water harvesting (AWH) has emerged as a promising avenue of research to address this pressing challenge. Here, we present a novel approach that re-purposes low-value petroleum feedstocks for AWH through their conversion to porous carbon (PC). Utilizing a potassium carbonate-assisted carbonization process, we develop PC from heavy and light cycle oils, and vacuum residue. While all sources yield materials with near superhydrophilic surfaces, only the cycle oils produce PC with high surface area and micoporous architectures. These engineered carbons demonstrate great water adsorption capacities of up to 23 wt% at 60% relative humidity (RH), surpassing commercially available carbon materials.
