In the last decade, interfacial solar steam generation (ISSG), powered by natural sunlight garnered significant attention due to its great potential for low‐cost and environmentally friendly clean water production in alignment with the global decarbonization efforts. In this review, we aim to share the knowledge and engage with a broader readership about the current progress of ISSG technology and the facing challenges to promote further advancements towards practical applications. The first part of this review assesses the current strategies for enhancing energy efficiency of ISSG systems, including optimizing light absorption, reducing energy losses, harvesting additional energy, and lowering evaporation enthalpy. Subsequently, we elucidate the current challenges faced by ISSG technologies, notably salt accumulation and bio‐fouling issues in practical applications and discuss contemporary methods to overcome these challenges. In the end, we introduce potential applications of ISSG, ranging from initial seawater desalination and industrial wastewater purification to power generation, sterilization, soil remediation, and innovative concept of solar sea farm, highlighting the promising potential of ISSG technology in contributing to sustainable and environmentally conscious practices. Based on the review and in‐depth understanding of these aspects, we propose the future research focuses to address potential issues in both fundamental research and practical applications.This article is protected by copyright.

“…Membrane technology with nanometer-sized pores plays an important role in the wide range of separation applications in water purification, industrial gas separation, biopharmaceutical drugs, food processing, and the petroleum industry. − However, current commercial membranes have limited permeability, low rejection rate, and poor solvent resistance due to a thick skin layer with a broad pore size variation. − Therefore, it is significant and challenging to fabricate a highly efficient membrane in terms of its pore size, shape, and number of diffusion channels in the separation layer.…”

Graphene oxide offers a promising opportunity to fabricate highly efficient and pressure-endurable membranes in terms of water permeability while demonstrating a high level of solute rejection. However, achieving higher permeance with an excellent separation capability is still challenging. Herein, we report a class of graphene oxide-lignin biopolymer (GOLB) membranes for the first time prepared by functionalizing GO nanosheets with lignin biopolymer extracted from plant pulp. Lignin biopolymer is the most abundant, green, low-cost, and environmentally friendly material with a variety of oxygen functional groups. The asprepared GOLB membranes have a unique laminated structure that provides an excellent rejection (>99%) for several organic dyes, proteins, and biomolecules with variable molecular weight and exhibits ultrawater permeance ∼1300 L m −2 h −1 bar −1 , more than that of reported GO-based membranes. It is interesting that due to larger interlayer spacing, such membranes show less rejection (<10%) for salts, i.e., NaCl, MgCl 2 , Na 2 SO 4 , etc. Furthermore, these membranes are highly stable up to 37 days in an aqueous environment and 28 days in acidic and basic solutions compared to pristine GO-based membranes.
