Atomic tuning of electrocatalysts

Nanowerk.com - 13 ноября, 2017 - 11:35
Efficient electrocatalysts lie at the heart of a series of significant energy conversion and storage technologies, and atomically precise understanding of the influences of component dopants is crucial for looking into the reaction mechanism and controlled synthesis of the desired electrocatalysts. Graphitic carbon nitride is a promising electrocatalytic material owing to its intrinsically high N content and abundant edge sites. This material has been researched towards some of the most significant electrocatalytic reactions including oxygen reduction/evolution reaction and hydro evolution reaction. New work has comprehensively explored the influences of component elements within graphitic carbon nitride motiety for electrocatalytic reactions.

Nanotechnology materials inspired by nature

Nanowerk.com - 10 ноября, 2017 - 13:25
The remarkable properties of some natural materials have motivated many researchers to synthesize biomimetic nanocomposites and other nanostructured materials that attempt to reproduce Nature's achievements. Recent research has indicated that the amplification of natural materials' mechanical properties far beyond those of the components that comprise them originates mainly from: 1) a hierarchical micro-/nanoscale architecture and 2) abundant effective interface interactions. A new progress report provides insight into the development of bio-inspired structural materials.
