Fully understanding the periodate (PI) activation system is still a great challenge, which calls for efficient heterogeneous catalysts with sophisticated structure. Herein, we developed "MOF-on-MXene" heterostructures. By constructing S-scheme heterostructures MXene/Z67450, internal electric field generated via Ti-O-Co bonds at interface, favoring excitation of photogenerated electrons, providing driving force accelerating charge transfer, and enhancing redox performances. Further contributed by synergy Co-N4 bonds, MXene/Z67450 composites exhibit enhanced ability activating to degrade organic pollutants building donor-catalyst-acceptor system. In presence light, degraded ∼100% tetracycline hydrochloride (TCH) in only 10 min. The active sites can react give intermediate MXene/Z67450-PI (*PI). As result, it efficiently reduced PI adsorption energy promoted decomposition formation holes/electrons, singlet oxygen (1O2) as well hydroxyl radical (•OH). addition, high stability, reusability, selectivity, environmental robustness. Our study provides research direction rationally designing MXene-based heterojunctions applying them

Abstract Solar‐driven interfacial evaporation (SIE) emerge as a promising technology to mitigate the worldwide freshwater shortage and energy crisis. Carbon nanotubes (CNTs) are widely used for construction of hydrogel evaporators. Nevertheless, their performance is still restricted by poor dispersibility strong hydrophilicity. Even worse, agglomeration CNTs will diminish formation porous structures within hydrogels weaken water transportation, finally resulting in decreased efficiency. To address those issues, with improved hydrophilicity successfully achieved via metal‐phenolic coordination chemistry‐based engineering. The networks (MPN)‐coated further incorporated into poly(vinyl alcohol) hydrogel, synergistically realize superior photothermal molecule activation. In this way, robust solar evaporator hierarchical pores fabricated efficient mass which achieves rate 2.9 kg m −2 h −1 under 1 sun illumination while maintaining stable operation long‐term high‐salt environments. Actual outdoor experiments catalytic gel acrylamide confirm robustness these MPN‐coated CNT‐based devices SIE. It believed that study paves new avenue toward development carbon‐based hierarchically evaporators, evaporation.

Abstract Enhancing interfacial evaporation rates and optimizing energy utilization remain critical challenges in solar‐driven steam generation. Natural fiber@MXene‐engineered chitosan aerogels with hierarchically oriented channels to achieve high‐efficiency generation are developed. The kapok fiber@MXene core–shell units (MKFs) construct photon‐entrapping topological networks that enhance light absorption while simultaneously reinforcing the aerogel's structural integrity durability for practical applications. microchannels establish thermodynamic potential gradients, facilitating spontaneous capillary‐driven water replenishment environmental thermal harvesting. Both experimental results COMSOL multiphysics simulations systematically demonstrate hierarchical pore transport, improve solar‐thermal/environmental synergy, promote downward diffusion of concentrated ions from surface, achieving an rate up 4.40 kg m −2 h −1 efficient salt rejection. Long‐term outdoor tests various corrosive wastewater solutions further validate evaporation. This study provides a theoretical foundation understanding interrelation between solar absorption, aerogel evaporators fiber‐pore architectures.

Abstract Organic photocatalysts generally suffer from insufficient near‐infrared light absorption and undesirable photogenerated charge transport properties, resulting in unfavorable hydrogen evolution performance water splitting. Hydrogen reaction (HER) is also known to be significantly influenced by the interfacial mass transfer a catalyst/H 2 O biphase system. Herein, for first time, highly stable floating hydrogen‐water cogeneration hybrid hydrogel that utilizes photothermal‐induced interface microenvironment variation accelerate sluggish photocatalytic splitting reported. Supported solar‐powered evaporation efficient vapor generation, rationally designed effectively transforms conventional liquid‐solid into gas‐solid interface. The presence of gas‐liquid coexistence state offers disordered loose hydrogen‐bond network while preserving proton channel, greatly reducing activation energy barriers. improved heat together with optimized pathways suppress electron‐hole recombination, integrated photothermal‐coupled solar exhibits excellent operational stability self‐adaptive rotation seawater, mitigating salt accumulation achieving an exceptional generation rate 4.71 kg m −2 h −1 hydrogen‐evolving 1961.25 µmol g under one sun illumination.
