Article Abstract
Engineering different two-dimensional materials into heterostructured membranes with unique physiochemical properties and molecular sieving channels offers an effective way to design membranes for fast and selective gas molecule transport. Here we develop a simple and versatile pyro-layering approach to fabricate heterostructured membranes from boron nitride nanosheets as the main scaffold and graphene nanosheets derived from a chitosan precursor as the filler. The rearrangement of the graphene nanosheets adjoining the boron nitride nanosheets during the pyro-layering treatment forms precise in-plane slit-like nanochannels and a plane-to-plane spacing of ~3.0 Å, thereby endowing specific gas transport pathways for selective hydrogen transport. The heterostructured membrane shows a high H permeability of 849 Barrer, with a H/CO selectivity of 290. This facile and scalable technique holds great promise for the fabrication of heterostructures as next-generation membranes for enhancing the efficiency of gas separation and purification processes.

Overcoming the high-temperature limitations of ceramic fuel cells (CFCs) requires the development of electrolytes capable of efficient proton transport at reduced operating temperatures. In this work, we introduced a surface-engineered SrTiO electrolyte coated with 10 mol%-CeO, forming a core-shell heterostructure that promoted the formation of oxygen vacancies localized at the interface. These vacancies significantly reduced the energy barrier for proton migration, enabling enhanced ionic conductivity at low operating temperatures.

Redox-responsive fluorescence regulation at heterointerfaces remains a critically underdeveloped yet strategically significant domain in advanced chemical sensing. Herein, we present an exciton modulation strategy enabled by heterojunction engineering between electron-rich CdSe quantum dots and an electron-deficient covalent triazine framework (CTF). This type-I CdSe@CTF heterostructure achieves nanoscale electronic decoupling and directional charge redistribution, unveiling a previously unreported fluorescence-switching mechanism governed by redox-triggered interfacial reconfiguration.

This study introduces a cost-effective, high-performance electrocatalyst based on non-noble metals for anion exchange membrane water electrolysis (AEMWE), crucial for sustainable hydrogen production. We describe a NiMn-oxo-phospho-selenide (NiMn-OPSe) catalyst, synthesized via a simple two-step method involving hydrothermal synthesis and controlled phospho-selenization. This approach combines morphology control, interface engineering, coordination tuning, and defect engineering, resulting in a needle-like structure that optimizes charge-transfer pathways and tunes the electronic structure, thereby enhancing catalytic performance.

The development of efficient nonprecious metal catalysts for the alkaline hydrogen oxidation reaction (HOR) catalyst in alkaline anion-exchange membrane fuel cells (AEMFCs) is of great significance. Nickel-based catalysts are considered to be promising HOR catalysts. Here, we report the interfacial engineering of reduced graphene oxide-supported Ni and Ni-Mo bimetallic nitrides (Ni-NiMoN/rGO), which exhibit excellent catalytic activity of alkaline HOR.
