Abstract
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.
期刊介绍：
Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
