Seamless synthesis and separation of exotic 2D materials using a liquid catalyst
Imagine melting a candle and letting the drops fall onto a piece of patterned sandpaper to cool versus dropping them into a bowl of water. Clearly, retrieving them nearly untouched or undamaged will be much easier from the surface of the water than from the surface of the rough sandpaper. This is one way to describe what currently happens with high-tech 2D materials that are adsorbed from their gas phase onto solid catalysts. The synthesis and subsequent transfer of these materials results in numerous defects, contamination and mechanical stress, compromising their highly sought-after properties. The EU-funded DirectSepa project is introducing liquid metal catalysts to replace solid ones in these processes. The technology promises unparalleled production speed and quality and could usher in a new era of innovation for 2D materials.
