“…4(b)). 37 The metal nanostructures on the surface of silicon NWs are capable of producing the LSPR effect, so the hybrid structure can improve the light absorption performance and achieve more than 91% light absorption in the solar spectral range, resulting in excellent photothermal conversion performance. Based on this specific structure, the evaporation rate reached 1.12 kg m À2 h À1 with a photothermal conversion efficiency of 72.8% under 1 sun illumination.…”

Water scarcity has become one of the most prevalent problems afflicting people throughout the world and is expected to grow worse in the future due limited resources and increasing demand. This problem calls out for an urgent need to develop inexpensive, stand-alone desalination and water purification technologies that can adopt water resource distribution, water quality conditions, economic status, and developing levels of communities. Solar energy is abundantly available and has become one of the most promising emerging strategies in sustainable water treatment technologies. In this review paper, we highlight the recent progress of solar-driven desalination and water purification technologies for clean water production. We begin by introducing the fundamental concepts of solar radiation, solar thermal conversion, and heat localization. Then, we review the key components of solar steam generation including solar-thermal conversion materials, water pathways, and heat insulators and the strategies to promote efficient solar-to-vapor conversion in terms of chemical regulation, structural engineering, and heat management to maximize solar absorption and to minimize heat loss. Next, we discuss an efficient design of a solar steam generation device using an integrated approach that accounts for the performance of photothermal materials, heat losses, and water supply with respect to the hot evaporation region. Last, existing challenges and future opportunities in both fundamental studies and practical implementations of solar steam generation for water purification are discussed.

“…Initially, the photothermal material was modified by loading silicon nanoparticles with silicon as a modifier [ 89 ], and the transformation of the material from hydrophilic to hydrophobic was achieved, as shown in Figure 8 b–d, which improved the absorption of sunlight ( Figure 8 e). Then by doping gold, silver, and other precious metals with silicon [ 90 , 91 ], the researchers realized the absorption of the full band of sunlight, which is used as a photothermal material generated by solar-thermal steam to study. Compared with silicon nanocrystals, germanium nanocrystals receive less attention, but have more excellent photothermal efficiency (Figrue 8f).…”

In response to the exhaustion of traditional energy, green and efficient energy conversion has attracted growing attention. The IVA group elements, especially carbon, are widely distributed and stable in the earth’s crust, and have received a lot of attention from scientists. The low-dimensional structures composed of IVA group elements have special energy band structure and electrical properties, which allow them to show more excellent performance in the fields of energy conversion. In recent years, the diversification of synthesis and optimization of properties of IVA group elements low-dimensional nanomaterials (IVA-LD) contributed to the flourishing development of related fields. This paper reviews the properties and synthesis methods of IVA-LD for energy conversion devices, as well as their current applications in major fields such as ion battery, moisture electricity generation, and solar-driven evaporation. Finally, the prospects and challenges faced by the IVA-LD in the field of energy conversion are discussed.
