General description
Tetramethylammonium hydroxide is a quaternary ammonium salt generally used as an anisotropic etchant for silicon due to its high silicon etching rate.[1][2]
Application
Tetramethylammonium hydroxide solution (25 wt.% solution in methanol) may be used in the synthesis of zirconium oxides via a modified sol-gel method with potential application as catalyst materials in CO hydrogenation.[3]
