Nowadays, sweet and drinkable water shortage is a global issue which has attracted widespread attention. Desalination of seawater as the greatest source of water on our planet using solar energy as the most abundant and green energy source for producing fresh water can help us address this issue. Interfacial solar desalination is a state-of-the-art, sustainable, green, and energy-efficient method that has been studied lately. One of the key parameters for researching this method with reasonable efficiency is a photothermal material. Herein, carbon-coated sand was synthesized using abundant, green, and low-cost materials (sand and sugar), and its performance as a photothermal material is investigated and reported. In this work, a three-dimensional (3D) system is introduced to develop the performance and efficiency of the system under real sun irradiation and natural circumstances. The salt rejection ability of the system is another important thing we should notice due to the high salinity of seawater that we want to desalinate. The superhydrophilic carbonized sand demonstrated a good evaporation rate of 1.53 kg/m2h and 82% efficiency under 1 sun irradiation and upright salt rejection ability, which exhibited its capability to be used in green solar-driven water vaporization technology for sweet water production. The effects of important parameters, including light intensity, wind speed, and environment temperature, on the evaporation rate using carbonized sand as a solar collector in a solar desalination system were studied in both laboratory and real systems.

“…In the past few years, researchers have been working with SVGs by combining novel photothermal materials (e.g., semiconductors (Sun et al 2020), carbon materials (Huo et al 2019), metal oxides (Liu et al 2018), and polymers (Li et al 2019), performing structural optimization (Zhang et al 2022;Duan et al 2023), and thermal management (Zhang et al 2020) to successfully develop advanced 3D interfacial evaporators for high evaporation rates and solar vapor e ciency. In recent years, researchers have made signi cant advancements in the development of low-cost evaporator materials (Han et al 2019; Gong et al 2023). However, creating a cost-effectiveness evaporator that combines salt resistance, high evaporation e ciency, and affordability remains a challenge.…”

Solar Vapor Generation (SVG) is a new green production technology that is gaining increasing attention for obtaining fresh water from seawater or wastewater. Currently, the evaporator substrates face challenges such as complex fabrication processes, high cost, and poor biodegradability. Lignocellulosic sponge (LS), as a sustainable material, exhibits characteristics such as hydrophilicity, excellent insulation properties, lightweight nature, and low cost. It is considered a highly promising material for evaporators. In this study, LS was modified to create an efficient evaporator with excellent salt resistance. The polyvinyl alcohol/carbon black (PVA/CB) gel-based photothermal coating was introduced to enhance the water evaporation rate significantly on the surface of the lignocellulosic sponge. Subsequently, a polydimethylsiloxane (PDMS) coating was sprayed on the interfacial steam generator surface to form a hydrophobic layer, effectively resisting salt accumulation on the evaporator surface. Simultaneously, the incorporation of degreased cotton as a one-dimensional water pathway enhanced the salt ion backflow and prevented salt crystallization at the hydrophilic/hydrophobic interface. The resulting porous sponge-based photothermal evaporator (PCP-LS) achieved a high evaporation rate of up to 3.2 kg m− 2h− 1 and demonstrated stable operation in high-concentration saltwater (20wt%). PCP-LS, as a cost-effective, easily fabricated, salt-tolerant, and environmentally friendly solar evaporator, holds great potential in seawater/wastewater treatment.

The field of 2D materials has advanced significantly with the emergence of MBenes, a new material derived from the MAX phases family, a novel class of materials that originates from the MAX phases family. Herein, this article explores the unique characteristics and morphological variations of MBenes, offering a comprehensive overview of their structural evolution. First, the discussion explores the evolutionary period of 2D MBenes associated with the several techniques for synthesizing, modifying, and characterizing MBenes to tailor their structure and enhance their functionality. The focus then shifts to the defect chemistry of MBenes, electronic, catalytic, and photothermal properties which play a crucial role in designing multifunctional solar‐driven hybrid systems. Second, the recent advancements and potentials of 2D MBenes in solar‐driven hybrid systems e.g. photo‐electro catalysis, hybrid solar evaporators for freshwater and thermoelectric generators, and phototherapy, emphasizing their crucial significance in tackling energy and environmental issues, are explored. The study further explores the fundamental principles that regulate the improved photocatalytic and photothermal characteristics of MBenes, highlighting their promise for effective utilization of solar energy and remediation of the environment. The study also thoroughly assesses MBenes' scalability, stability, and cost effectiveness in solar‐driven systems. Current insights and future directions allow researchers to utilize MBenes for sustainable and varied applications. This review regarding MBenes will be valuable to early researchers intrigued with synthesizing and utilizing 2D materials for solar‐powered water‐energy‐fuel and phototherapy systems.
