1. Scope of Research
Our focuses are to synthesis functional materials including solid catalysts and to design the catalyst based on chemical& catalytic reaction engineering. We synthesize new materials, by which catalytic reaction processes are developed forsolving the environmental/energy problems.

2. Research Topics
Synthesis of nano-zeolites and their application
Zeolite, crystalline aluminosilicate, possesses solid acidity withordered-microporous structure. Preparation for nano-zeolites
with crystal size below 100 nm and their application to light olefin
synthesis are examined.
 Preparation of mono-dispersed nano-zeolite Preparation of aluminoferrisilicate
 Synthesis for C2～C4 light olefins by nano-zeolite catalyst

Production of useful chemicals from untreatedhydrocarbon resources
Conversion of unused hydrocarbon resources into usefulchemicals is one of the most important issues. Petrochemicalrelated useful chemicals are produced by catalytic decompositionand hydrocracking of the untreated hydrocarbon resources.
 Dehydration of polyol
Propylene and allyl alcohol production from glycerol
Butadiene production from erythritol
 Hydrocracking of C-C bonds in biomass molecules
Aromatics and phenols production from lignin andlow-rank coal
