Crystalline Carbon Nitrides for Sustainable Energy Use

Building a clean and efficient energy system is essential for sustainable development and places stringent demands on advanced materials design. Crystalline carbon nitride (CCN), as a metal-free material composed of earth-abundant elements, is promising for sustainable energy conversion and storage owing to its long-range ordered framework, tunable electronic structure and high chemical stability. Compared with conventional amorphous or polymeric carbon nitrides, the crystalline nature of CCN effectively suppresses defect-induced charge recombination and enables more efficient charge transport and interfacial reaction kinetics. This talk focuses on the rational design and controlled synthesis of CCN-based materials for photo(electro)catalytic energy conversion and electrochemical energy storage applications. By tailoring crystal phase, dimensionality, defect chemistry and heterointerfaces, the structure-activity relationships governing light absorption, charge separation, surface reaction pathways and energy storage behavior are elucidated. This talk highlights perspectives and opportunities for crystalline carbon nitrides as a versatile and scalable material platform for high-efficiency new energy devices.
