“…To solve this problem, controlling the migration rate of ions should be considered. A metal–organic framework (MOF) with subnanopores has been confirmed to have confinement effects to control the release of ions due to its dehydration and hydration process. − Therefore, we attempted to induce an ion trap within MOF cages and efficiently convert the ion gradient into a sustainable current.…”

The energy conversion in plant chloroplast is carried out by pumping protons into the thylakoid for driving ATP synthesis. Inspired by ion active transport in living organisms, we attempted to design an artificial ion pump induced by subnanoconfinement effects. This ionic device uses two polarity functional nanoporous films as ion-selective valves at both ends and UiO-66 metal−organic framework-filled microchannels as ion storage cavities. In the charging process, ions could be pumped into the central cavities by nanovalves, which produced an ion gradient 10 to 100 times higher than the bulk, and were trapped within the subnanocages by dehydration. In the discharging process, the enriched ions were rehydrated and slowly released by the surface charge of the nanovalves, producing a sustainable ion current. The ion storage efficiency of this nanofluidic device could be improved to 60.3%, and the release time of ion current was also prolonged by 1 order of magnitude. This work combines the active and passive transport of ions to realize fast storage and slow release of ionic current, which provides an ion gradient-mediated novel energy conversion strategy.

“…Compared to their individual components, heterojunctions exhibit distinct traits that make them valuable in materials science, catalysis, and energy research. The development of nanoscience and technology has led to various synthesis methods for heterojunctions, enabling more effective fundamental studies and practical applications. − Metal–organic frameworks (MOFs) possess inherent qualities such as facile accessibility of channels, active metal nodes that are evenly distributed, and a wide range of coordination environments, − which render them immensely versatile frameworks for fabricating transition metal-based electrocatalysts characterized by exceptional levels of efficiency. − Especially, Co-based MOFs have demonstrated great potential in OER. − Coincidentally, CoFe layer double hydroxide (LDH) has been widely recognized as an exceptionally efficient catalyst for OER, which can be attributed to the synergistic effects between Co and Fe metals, which significantly enhance the inherent reactivity of each active site. − The controlled and precise deposition of CoFe-LDH onto the surface of Co-based MOFs represents a promising strategy to enhance the catalytic activity for OER by synergistically harnessing the advantageous properties of both materials. However, the feasibility of fabricating CoFe-LDH/Co-MOF heterostructures with a hollow morphology and subsequently optimizing the local electronic structure to significantly augment the OER activity remains challenging.…”

Assembling a heterostructure is an effective strategy for enhancing the electrocatalytic activity of hybrid materials. Herein, CoFe-layered double hydroxide and Co-metal−organic framework (CoFe-LDH/Co-MOF) hollow heterostructure nanorod arrays are synthesized. First, [Co(DIPL)(H 3 BTC)-(H 2 O) 2 ] n [named as Co-MOF, DIPL = 2,6-di(pyrid-4-yl)-4-phenylpyridine, H 3 BTC = 1,3,5-benzenetricarboxylic acid] crystalline materials with a uniform hollow structure were prepared on the nickel foam. The CoFe-LDH/Co-MOF composite perfectly inherits the original hollow nanorod array morphology after the subsequent electrodeposition process. Optimized CoFe-LDH/Co-MOF hollow heterostructure nanorod arrays display excellent performance in oxygen evolution reaction (OER) with ultralow overpotentials of 215 mV to deliver current densities of 10 mA cm −2 and maintain the electrocatalytic activity for a duration as long as 220 h, ranking it one of the non-noble metal-based electrocatalysts for OER. Density functional theory calculations validate the reduction in free energy for the rate-determining step by the synergistic effect of Co-MOF and CoFe-LDH, with the increased charge density and noticeable electron transfer at the Co−O site, which highlights the capability of Co-MOF to finely adjust the electronic structure and facilitate the creation of active sites. This work establishes an experimental and theoretical basis for promoting efficient water splitting through the design of heterostructures in catalysts.
