Full Title

Full titles differ between systems:

IPC:

Catalysts, in general, characterised by their form or physical properties > characterised by their crystalline properties, e.g. semi-crystalline > having a two-dimensional [2D] layered crystalline structure, e.g. layered double hydroxide [LDH]

CPC:

Catalysts, in general, characterised by their form or physical properties > characterised by their crystalline properties, e.g. semi-crystalline (catalysts comprising carbon B01J21/18; molecular sieves B01J29/00) > having a two-dimensional [2D] layered crystalline structure, e.g. layered double hydroxide [LDH]

No child classifications to compare. This is a leaf node in both IPC and CPC.
