Research Overview

Our research is focused on determination of reaction mechanisms and active sites in surface catalysis by metals, metal oxides, metal-oxygen clusters, and olefin polymerization catalysts. Characterization and manipulation of catalyst surfaces by scanning tunneling microscopy (STM), and energy environmental catalysts are also our major research concerns. A goal of our research is to demonstrate the design of new materials and of new catalysts starting from the discovery of novel surface reactions, and thus to establish a new paradigm for the development of new catalytic science and technology.

Characterization and Manipulation of Catalyst Surfaces by Scanning Tunneling Microscopy

Our STM studies of heteropolyacids (HPAs) span a wide range of issues in catalysis and surface science. These examples include (i) determination of redox and acid properties of bulk HPA catalysts from surface properties of nanostructured HPA monolayers, (ii) probing molecular shape, orientation, and packing of self-assembled HPA arrays, (iii) identification of individual molecules in the mixed HPA catalysts, and (iv) fabrication of atomically sharp and stable STM probe utilizing HPA single molecule.

Energy Environmental Catalysts

Our research areas related to energy and environmental catalysts are (i) hydrogen production for fuel cell, (ii) hydrogen storage, (iii) decomposition of hazardous organic materials, and (iv) electrode materials for pseudo-EDLC and hybrid-EDLC.
