Few layer black phosphorus is a new two-dimensional material which of great interest for applications, mainly in electronics. However, its lack stability severely limits our ability to synthesise and process this material.

Layered double hydroxides (LDHs) are low-dimensional materials that act as benchmark catalysts for the oxygen evolution reaction (OER). Many LDH properties affecting OER have been studied to reach optimal efficiency, but no systematic studies concerning influence of interlayer space developed. In this context, these allow a large tunability in their chemical composition enabling substitution anion and therefore modifying exclusively basal space. Here, we synthesize by exchange reactions...
