“…35 MXene phase Ti3C2 on multi-walled carbon nanotubes (MWCNT) were vacuum loaded onto MCE paper (mass loading of 2.0 g m -2 ) which had a desalination rate of 1.32 kg m -2 h -1 . 36 Our group previously reported HfN interfaces capable of desalinating at 1.20 kg m -2 h -1 with a mass loading of 2.5 g m -10 refractory materials in such designs can potentially result in higher rates than those currently reported. 44,48,[63][64][65] The stability of TMC interfaces were tested over the course of 10 hours and the rate of evaporation remained unchanged (Figure 3A).…”

To combat the dwindling supply of freshwater, solar-driven desalination using plasmonic nanomaterials has emerged as a promising and renewable solution. Effective materials must exhibit high solar-to-vapor conversion efficiencies, be inexpensive, chemically stable, and maintain performance over time. Refractory plasmonic carbide nanomaterials are exciting candidates that could meet these demands but have not been as widely explored. Here, we investigate plasmonic carbide interfaces made of TiC, ZrC, and HfC nanoparticles loaded onto to a mixed cellulose ester (MCE) membrane gain insight into their solar-vapor generation and desalination potential. Evaporation rates and efficiencies were determined for tap water and saltwater with varying salt concentrations. Desalination using Atlantic Ocean water under 1 sun intensity yielded rates of 1.26 ± 0.01, 1.18 ± 0.02, and 1.40 ± 0.01 kg m-2 h-1, with efficiencies of 86, 80, and 96% for TiC, ZrC, and HfC, respectively, under 1 sun illumination. Carbide interfaces effectively removed salt and metal ions from the water and were able to reject salt over extended periods of desalination and high salt concentrations of up to 35%. The effect of ambient temperature and relative humidity on the desalination process was also investigated which showed that the evaporation rates and efficiencies decrease with increasing humidity and decreasing room temperature. However, the performance of HfC was less affected by the changes in the ambient conditions compared to TiC and ZrC.

“…Material compositing is to compound differently charged materials by bonding or electrostatic interactions to change the charged and macroscopic properties of membranes composed of a single material, such as anti-swelling ability, and then improve the ability of nanochannels to regulate ion transport. [91][92][93] For instance, prolonged immersion of the membranes in water causes swelling, which expands the interlayer spacing and weakens the ion selectivity of nanochannels. Yin et al [94] fabricated composite membranes using negatively charged MXene and GO nanosheets (Figure 10a).…”

2D nanofluidic membranes are capable of regulating ion transport toward various applications concerning energy and environment, which is primarily contributed by the excess charge on the interior surface of narrow nanoscale pores. However, there is still a lack of comprehensive summaries and discussions on the surface charge modification principles and strategies of 2D nanofluidic membranes, as well as the practical applications of charge‐modified 2D nanofluidic membranes for regulating ion transport. In this review, the surface charge modification principles and charge modification methods of 2D nanofluidic membranes are first introduced in detail, which is of great significance for improving the ion regulation capability of membranes and realizing the design of nanochannel materials. Next, recent advances in the two typical applications of concentration cells and water treatment based on charge‐modified 2D nanofluidic membranes are summarized. Finally, some challenges and prospects related to charge‐modified 2D nanofluidic membranes are discussed to indicate directions for future research in this field. It is anticipated that this review will provide valuable strategies for the development of high‐performance charge‐modified 2D nanofluidic membranes toward energy and environment applications.

Global energy and environmental problems are becoming increasingly prominent, and the shortage of freshwater resources has been plaguing many countries and regions in the world. Solar steam generation (SSG) has emerged as a green, low‐cost and efficient strategy for freshwater production, which has attracted enormous attention in recent years. Furthermore, various photothermal materials and structural designs for the preparation of efficient SSG systems have been widely reported. Among them, metal‐based photothermal materials are abundant, and the exploration on metal‐based SSG systems is one of the important research directions. In this review, the basic concepts and design objectives of current metal‐based SSG systems are first introduced, as well as advances in the recent development of metal‐based photothermal materials, including photothermal mechanisms, and preparation methods. The evaluation criteria of the SSG system are further described. Then the development of metal‐based SSG systems is summarized in terms of structural design, functional modules (light absorption, thermal management, water transport, salt rejection, etc.), and potential applications (wastewater treatment, sterilization and other fields). Finally, the main challenges and future prospects of metal‐based SSG systems in basic research and practical applications are emphasized.
