Benzene-Linked Polymeric Carbon Nitride for Enhanced Photocatalytic Hydrogen Production

“…Polymeric carbon nitride (PCN) has shown promise in this regard, but its photocatalytic activity is hindered by limitations such as low specific surface area, limited visible light yield, and rapid recombination of electron/hole pairs. 3−6 To overcome these challenges, various methods have been employed to enhance PCN's photocatalytic activity, including element doping, 7,8 nanostructure formation, 9,10 heterostructure construction, 11,12 and developing a crystalline allotrope of PCN, including poly(heptazine-triazine) imide. 13,14 Molecular doping could regulate the molecular structure of PCN through the introduction of different functional groups (DFGs).…”

Controlled Synthesis of Hierarchical Nanostructured Metal Ferrite Microspheres for Enhanced Electrocatalytic Oxygen Evolution Reaction

“…The developing demand for clean energy resources and attention to environmental pollution triggered by fossil fuels are inspiring a strong research interest in energy storage and conversion from environment-friendly renewable energy. , The oxygen evolution reaction (OER), as an important chemical form process to produce and store renewable energy, has led to many types of research in the past decade years. − However, the anodic OER kinetics is sluggish and still possesses a critical bottleneck to improve the water-splitting effectiveness due to the four-electron transfer process for O–H bond breaking and O–O bond formation. , Therefore, an effective electrocatalyst is required to drive a higher current density at a lower overpotential and thus enhance the energy conversion efficiency. , As we know, metal oxides are always the efficient active and durable electrocatalysts for OER. In particular, RuO 2 and IrO 2 among metal oxides are considered to be the best OER electrocatalysts in both alkaline and acidic solutions; nevertheless, the price and scarcity restrained these noble oxides’ large-scale practical applications.…”
