Properties of Hierarchy Zeolite Obtained From Obsidian and Perlite
A method for obtaining hierarchical BEA, MOR, MFI, MTW, and GIS zeolites and nanocomposites by partial recrystallization of perlite and obsidian in the presence of polyquaternary ammonium salts, which act as structure-directing agents, is proposed. The obtained materials are characterized by a developed specific surface, the presence of Lewis (up to 98 μmol/g) and Bronsted (5-105 μmol/g) acid sites and show catalytic activity in the process of 1,1-diethoxyethane production from acetaldehyde and ethanol.
期刊介绍：
Theoretical and Experimental Chemistry is a journal for the rapid publication of research communications and reviews on modern problems of physical chemistry such as:
a) physicochemical bases, principles, and methods for creation of novel processes, compounds, and materials;
b) physicochemical principles of chemical process control, influence of external physical forces on chemical reactions;
c) physical nanochemistry, nanostructures and nanomaterials, functional nanomaterials, size-dependent properties of materials.
