Original Paper


Two types of combinatorial chemical reactors have been developed for high-throughput experimentation of catalysts that attract much interest from global environmental viewpoints. The high vacuum combinatorial laser MBE system was applied to the preparation of thin film library of TiO2 with its film thickness gradually increased, which resulted in the discovery of new phenomenon indicating a quantum size effect in TiO2 photo-catalysis. The combinatorial autoclave reactor was made to explore new catalysts and optimum reaction conditions efficiently for alternating CO2 copolymerization with epoxide (oxirane) to form bio-degradable polycarbonates. Some preliminary results are reported on the CO2 copolymerization with propylene oxide, as a means of CO2 fixation into chemically useful material.
