Photocatalytic water splitting is a clean energy technology that uses sunlight to split water into oxygen and hydrogen in order to produce green hydrogen—a clean fuel—without relying on fossil fuels.

Illustration showing how a composite material containing sheets of boron nitride (lattice of blue and silver balls) and nanoparticles of titanium dioxide (gray spheres) uses long-wave ultraviolet ...

Chinese researchers recently found that a near-infrared reflective blending coating had better optical and cooling performance, thereby reducing the absorbed energy of pavement in permafrost regions ...
