Summary: The ternary composite based on g-C3N4 (CeO2/CN/NH2-MIL-101(Fe)) exhibited superior photocatalytic activities for H2O reduction to produce H-2 and degradation of 2,4-dichlorophenol (2,4-DCP). The enhanced photoactivities were attributed to the synergistic effects of proper band alignment and close interfacial contact of the three components, which significantly promoted charge transfer and separation. The degradation of 2,4-DCP over the composite was found to be primarily dominated by (OH)· radical, as confirmed by scavenger trapping experiments and electron para-magnetic resonance (EPR) study.

Summary: Accelerating charge separation and transfer and increasing visible light absorption are crucial for efficient photocatalytic hydrogen production via water splitting. In this study, we fabricated an in-plane graphited nanocarbon-conjugated polymeric carbon nitride (GNC-C3N4) nanosheet heterostructure photocatalyst for the first time. The incorporation of GNC into the conjugate network of C3N4 significantly enhanced light harvesting and improved charge separation and transfer through the built-in electric field and intimate interface.

Summary: Metal-organic frameworks (MOFs) and covalent-organic frameworks (COFs) have attracted significant attention as highly crystalline advanced permeable materials with large surface area, ordered pores/channels, and controllable structure. However, their low structural stability and electrical conductivities limit their applications in photocatalysis and energy storage/conversion. Extensive research has focused on maximizing their advantages and overcoming these limitations. This review article provides a background and timeline of COF/MOF development, discusses synthetic procedures, recent achievements, and milestones in CO2 reduction, hydrogen production, lithium-ion batteries, and supercapacitors, and explores the challenges and future prospects for high-performance COF/MOF materials in photocatalysis and electrochemical energy storage.
