“…The solar to steam efficiency ( η ) was computed via eqn (2): 12,43 where ν (kg m −2 h −1 ) is the rate of vapor generation under steady-state conditions irradiation and Q in (mW cm −2 ) represents the incoming solar irradiation intensity. H e is the sum of the latent heat and sensible heat enthalpy of the whole water-vapor phase shift, which is computed as follows: H e = C p Δ T + Δhwhere, C p is the specific heat capacity of water which is equal to 4.18 J g −1 k −1 , Δ T is the change of temperature of the water, and Δh refers to the latent heat of vaporization on the relative temperature (2394 kJ kg −1 ).…”

“…Ibrahim's team designed an Ag/CuO‐reduced graphene oxide (rGO) solar evaporator for seawater desalination. [ 136 ] Desalination performance of the evaporator was evaluated with the difference of ion concentrations of artificial seawater reservoir and condensed freshwater. The result shows a significant reduction of Mg 2+ , Ca 2+ , and Na 2+ ions, which the concentrations dropped from the original values of 1500, 1000, and 1000 mg L −1 to 10, 3.4, 7.2 mg L −1 respectively.…”

Solar steam generation has drawn high levels of attention from the research community in recent years due to its wide application and abundantly available energy source—sunlight. To the best of the author's knowledge, a specialized overview of photothermal semiconductor solar steam generation has not been conducted to date. In this review, the recently reported solar evaporators using metal oxide semiconductors as the photoabsorber material are investigated, from the perspective of nanostructure, synthesis method, and installation method. A timeline sequence map is generated with the CiteSpace analysis tool to visualize the trend of metal oxide semiconductors as photoabsorbers. The nanostructure of metal oxide semiconductor is emphasized, due to its significant effect on regulating photothermal efficiency in solar steam generation. In addition, other considerations are suggested to enable a fair evaluation of future synthesized photoabsorbers, including cost, stability, reproducibility, recyclability, and regenerative ability. A brief summary of divergent application of solar steam generation is conducted to show the merits of solar steam generation, as well to provide insights for production of photoabsorbers targeted to varying usage and scenarios. Furthermore, the challenges and opportunities of metal oxide solar steam generation system are elaborated from the viewpoint of the authors, with the aim to provide useful insights for future development of photothermal solar steam generation.

“…Polyurethane was used as a carrier and thermal insulator. The Ag/CuO-RGO-PU film has an average of 2.6 kg m −2 h −1 under one solar irradiation, and the evaporation rate and solar thermal efficiency are as high as 92.5% [ 89 ]. The absence of a power source and the potential portability of the device represents an attractive solution for long-term desalination, and these studies are of great value in advancing our understanding of efficient photothermal conversion.…”

Graphene-based membranes have unique nanochannels and can offer advantageous properties for the water desalination process. Although tremendous efforts have been devoted to heightening membrane performance and broadening their application, there is still lack of a systematic literature review on the development and future directions of graphene-based membranes for desalination. In this mini-review, literature published between 2011 and 2022 were analyzed by using the bibliometric method. We found that the major contributors to these publications and the highest citations were from China and the USA. Nearly 80% of author keywords in this analysis were used less than twice, showing the broad interest and great dispersion in this field. The recent advances, remaining gaps, and strategies for future research, were discussed. The development of new multifunctional nanocomposite materials, heat-driven/solar-driven seawater desalination, and large-scale industrial applications, will be important research directions in the future. This literature analysis summarized the recent development of the graphene-based membranes for desalination application, and will be useful for researchers in gaining new insights into this field.
