This review highlights hydrogel-based self-floating catalysts as innovative interfacial platforms for solar-driven chemistry. By establishing stable three-phase interfaces
these materials overcome traditional mass-transfer limitations and catalyst agglomeration. We analyze core construction strategies and demonstrate their versatile applications in pollutant degradation
hydrogen production
and desalination.
Hydrogel-based self-floating catalytic materials have become a key interfacial platform in the field of solar-driven chemistry
effectively solving the difficulties of traditional powder catalysts in the aqueous phase
such as easy agglomeration
sedimentation
and limited mass transfer. In this study
the design strategy
structural properties
and interfacial advantages of these materials were systematically described
and the mechanisms of precursor mixing
in situ
synthesis
and post-modification in regulating the distribution of active sites
gel structure formation
and multifunctional integration were analyzed. Through the construction of stable three-phase interfaces
the materials form a reaction microenvironment with a generalized enhancement effect. The structural design significantly improves the light trapping efficiency and carrier separation performance in photocatalytic processes and simultaneously strengthens the mass transfer process and local reactant concentration in peroxide activation reactions
establishing a synergistic system in which the adsorption
enrichment
and catalytic processes are tightly coupled. Successful applications in the fields of organic pollutant degradation
solar-driven chemical synthesis
and interfacial evaporation have demonstrated the wide applicability of this technology. By systematically combining the research progress in this field
this study aims to provide a theoretical basis for the development of efficient and stable interfacial catalytic platforms and promote the development of sustainable environmental remediation and energy conversion technologies.
