Abstract Electrochemical nitrite reduction reaction (NO 2 RR) has emerged as a promising alternative approach for ammonia (NH 3 ) production, offering both energy efficiency and environmental sustainability. The rational regulation of active hydrogen (*H) is pivotal NO − ‐to‐NH conversion, yet it remains significant challenge in the context RR. In this study, molybdenum boride (MBene) multilayers are introduced an electronic support to integrate with palladium (Pd) nanoparticles, creating dual catalytic sites that effectively balance adsorption *H *NO , thereby enabling synergistic catalysis Theoretical experimental analyses revealed efficiently generated on Pd subsequently undergoes spillover ‐adsorbed MBene surfaces, facilitating accelerated hydrogenation NH synthesis. Consequently, Pd/MBene catalyst demonstrated exceptional performance, achieving high Faradaic 89%, yield rate 16.9 mg h −1 cat remarkable cycling stability at low applied potential ‐0.3 V versus RHE. Motivated by outstanding RR further utilized cathode construct Zn‐nitrite formaldehyde‐nitrite batteries. These systems functionality simultaneous production electricity generation, highlighting versatile efficient sustainable conversion.

MXenes and MBenes, advanced two-dimensional materials with outstanding structural electronic properties, are gaining prominence in energy conversion storage, particularly for the oxygen reduction reaction (ORR). ORR, essential fuel cells metal-air batteries, suffers from sluggish kinetics, efficient catalysts. While noble metals like platinum excel this role, their high cost scarcity necessitate alternatives. MXenes, consisting of transition metal carbides, nitrides, or carbonitrides, exhibit metallic conductivity tunable surface chemistry, making them ideal ORR catalysis. Similarly, nitride-based analogs, show great promise. Optimization methods selective etching, functionalization, heteroatom doping significantly enhance catalytic performance. This review explores synthesis, structure, mechanisms highlighting recent progress, addressing stability scalability challenges, identifying future directions improving efficiency sustainable applications.

ABSTRACT Solar‐powered interfacial evaporation technology is seen as a potential way to alleviate the crisis of water scarcity through seawater desalination. The key success this hinges upon efficient conversion solar energy into heat energy, which intimately connected with innovative development composite photothermal membranes. In study, polyaniline (PANI) excellent light absorption and carbon black (CB) good stability were added polymer material polyaryl ether nitrile (PEN), PANI/CB‐PEN nanofiber membrane was prepared by electrospinning blending. Due PEN polymer, evaporator has salt resistance stability. results show that fiber best effect when reaction time 80 min CB content 50.0%. temperature can reach 68.6°C, rate 1.51 kg m −2 h −1 , while 1.38 in 3.5% NaCl brine. efficiency 94.17%. membrane‐based device demonstrates sustained performance repeated tests, showing promising for long‐term, scalable solar‐powered desalination applications.

Solar-driven water evaporation is considered as the sustainable approach to alleviate freshwater resource crisis through direct use of solar energy. However, it still challenging achieve multifunctional evaporators equipped with both high and purification performance handle practical complex wastewater. Here, a simple cost-effective 3D evaporator prepared by alternately decorating commercial sponge FeOOH quantum dots (FQDs) supported MXene sheets composites chitosan hydrogel coatings for enabling organic wastewater photodegradation simultaneously. allow excellent photothermal conversion performance, hydrophilic coated interconnecting skeleton structures serve mass transfer transport channels. The Fenton-catalytic FQDs anchored on surface accept photo-generated electrons induce pollutant photo-Fenton degradation reaction under sunlight irradiation. resulting possesses rate 2.54 kg m
