The outstanding chemical and physical properties of 2D materials, together with their atomically thin nature, make them ideal candidates for metaphotonic device integration and construction, which requires deep subwavelength light–matter interaction to achieve optical functionalities beyond conventional optical phenomena observed in naturally available materials. In addition to their intrinsic properties, the possibility to further manipulate the properties of 2D materials via chemical or physical engineering dramatically enhances their capability, evoking new science on light–matter interaction, leading to leaped performance of existing functional devices and giving birth to new metaphotonic devices that were unattainable previously. Comprehensive understanding of the intrinsic properties of 2D materials, approaches and capabilities for chemical and physical engineering methods, the resulting property modifications and novel functionalities, and applications of metaphotonic devices are provided in this review. Through reviewing the detailed progress in each aspect and the state-of-the-art achievement, insightful analyses of the outstanding challenges and future directions are elucidated in this cross-disciplinary comprehensive review with the aim to provide an overall development picture in the field of 2D material metaphotonics and promote rapid progress in this fast emerging and prosperous field.

“…Therefore, the adjustment of the light absorption performance of solar absorbers is an effective method to achieve excellent thermal energy generation and a high evaporation rate. Until now, the photothermal conversion materials of solar absorbers which have been reported could be divided into four kinds: carbon-based materials [16,23], semiconductors [17,24], and metal-based plasmonic materials [18,25], and conjugated polymers [19,26]. Also, the other photothermal conversion materials, such as aggregation-induced emission (AIE) photothermal molecules [27], conjugated small molecules [28], and metal-organic framework derived photothermal conversion materials [29] have been applied in the solar-driven evaporation field.…”

With the development of the industry, water pollution and shortage have become serious global problems. Owing to the abundance of seawater storage on earth, efficient solar-driven evaporation is a promising approach to relieve the freshwater shortage. The solar-driven evaporation has attracted tremendous attention due to its potential application in the seawater desalination and wastewater treatment fields. Also, the solar-driven evaporation efficiency can be enhanced by designing both solar absorbers and structures. Up to now, many strategies have been explored to achieve high solar-driven evaporation efficiency, mainly including the selection of photothermal conversion materials and structure optimization. In this review, the solar absorbers, structural designs, and energy management are proposed as the keys for high performance solar-driven evaporation systems. We report four kinds of solar absorbers based on different photothermal conversion mechanisms, substrate structure designs, and energy management methods for the purpose to achieve high conversion efficiency. And we also systematically investigate the available salt-rejections strategies for seawater desalination. This review aims to summarize the current development of efficient solar-driven evaporation systems and provide insights into the photothermal conversion materials, structural designs, and energy management. Finally, we propose the perspectives of the salt-rejection technologies for seawater desalination.

“…Freshwater is a very scarce and precious resource for drinking, agriculture, and industry due to its low reserve and uneven distribution. − Considerable amount of freshwater is still polluted by organic dyes in the form of industrial effluents, agricultural runoff, and chemical spills, intensifying the freshwater resource crisis. , Although the earth is covered with water by 70%, around 96.5% is seawater. , It is therefore key to solving the shortage of freshwater that the separation-purification technology for freshwater from seawater and wastewater should be continuously and studiously developed in the world. Currently, two methods including thermal desalination and reverse osmosis technology have been widely utilized for the desalination of seawater. − As for thermal desalination, solar evaporation is viewed as a hopeful and potential technology due to using unlimited solar energy. − Based on the solar steam system, there are three aspects for photothermal materials to achieve highly efficient evaporation . First, novel materials must be preferentially developed, which have strong and broad-band absorption of sunlight to maximize the input of energy.…”

“…Based on the above aspects of photothermal materials, considerable and continuous efforts have been made to design and synthesize an efficient absorber of sunlight . From the reported work, the photothermal materials are mainly focused on the metal-based nanomaterials, − which utilize surface plasmon resonance (SPR) and localized SPR mechanisms to achieve photothermal conversion; carbon-based materials, ,− using conjugation and hyperconjugation effects to achieve light-converted heat; inorganic semiconductors; − and organic polymers, − using photothermal electronic excitation to achieve light-converted heat. Besides, other materials such as MXenes (M: transition metal, X: C or N), , black phosphorus-based nanospheres, , and perovskite oxide ceramics (Sm 0.5 Sr 0.5 CoO 3−δ and La 0.5 Sr 0.5 Co 0.5 Ni 0.5 O 3−δ ) are also used to serve as photothermal materials which offer an excellent photothermal conversion under sun illumination.…”

Production of clean water from seawater and wastewater is significant through photothermal evaporation using unlimited solar energy. Here, we constructed a double-layer-structure evaporator (DLSE) consisting of nickel foam@reduced graphene oxide–carbon nanotube (NF@RGO–CNT) as a solar absorber and an expanded polyethylene foam (EPE)/thermoelectric (TE) module as a heat insulator, which was used in various water purification processes and simultaneous electricity generation. The reduced graphene oxide covered on the surface of nickel foam increases broad-band absorption of sunlight and weakens the thermal emittance, and its coarse surface decreases the reflectance of light, which ensures the largest photo-to-heat conversion efficiency. Compared with the pristine nickel foam, NF@RGO–CNT has a low thermal conductivity to achieve localized high temperatures, which favors the evaporation of water on the interfacial surface. As such, a high water evaporation rate of 1.37 kg m–2 h–1 together with a photothermal conversion efficiency of 96.4% was achieved over the NF@RGO–CNT under 1 kW/m2. Meanwhile, the thermoelectricity during solar evaporation is generated by utilizing the TE module instead of EPE, in which a maximum output power of 0.251 W m–2 was achieved under 1 kW/m2. In addition, clean water can be produced using DLSE equipment from various water sources such as brine water, organic wastewater, seawater, and lake water, in which the quality of the evaporated water is better than drinkable water standard, and the evaporation performance is comparable to that of pure water.
