Photothermal effectiveness of microporous carbon nanospheres incorporated with polysulfone in direct contact membrane distillation.

Carbon nano-spheres (CNS) were synthesized a hydrothermal method using d-glucose as a precursor, followed by pyrolysis in a nitrogen atmosphere. The resulting CNS were integrated into polysulfone (PSF) membranes to enhance their photothermal properties. Characterization using various techniques revealed improved thermal properties upon CNS inclusion, with a notable increase in membrane surface temperature and enhancement of contact angle (CA) and liquid entry pressure (LEP).
