Fig 3 3D-graphene photo-thermal water treatment. (a) Scheme of the lab made solar still. (b)The concentrations of five primary ions in seawater sample before (original) and after solar thermal purification. (c, d) The concentrations of ions in the actual lake water before (original) and after purification. (e, f) The photographs of agar plates inoculated with actual seawater (East Sea) before (original) and after purification under solar illumination of 1sun, respectively. (g, h) The photographs of agar plates inoculated with lake water from Beijing before (original) and after purification under solar illumination of 1 sun, respectively, Adapted with permission from Ref. 83, Copyright 2018, Elsevier Ltd.; (i)The mass change t in rGO foam and pure water under solar illumination of 1 sun. Adapted with permission from Ref. 82, Copyright 2019, Wiley-VCH; (j) Sewage treatment performance by 3DG under solar illumination. The contaminated water has a strong absorption peak around 465 or 663 nm due to the methylorange (MO) or methyleneblue (MB) absorption, respectively. After the solar treatment, the water contained no MO or MB, as evidenced by the near zero optical absorbance, showing an excellent sewage treatment performance. Adapted with permission from Ref. 80.
