Descripción

General description

LUDOX^® HS-40 colloidal silica is used as a silicon (Si) source in the synthesis of zeolites, sulphate sodalite, and aluminosilicate gels.

Application

LUDOX^® HS-40 colloidal silica is utilized:

• As a template for generating mesopores
• As an excellent binder that binds catalyst components together and provides high mechanical strength without changing catalytic properties
• As a substrate to enhance substrate adhesion in zeolites
• In the preparation of nitrogen-doped carbon (NMC), which serves as catalyst support
