Catalysis for Value-Added Chemicals by using CO2 as Oxygen Source

초록

CO2 emission is worse and worse. It comes mostly from power plant and various energy sector and chemical plants due to energy requirement. We’ve tried to capture and storage (CCS) but need to combine with utilization by transforming CO2 into fuels or chemicals. However, CO2 can be a promising chemical feedstock as a cheap, abundant, and non-toxic feedstock, even though CO2 already has been utilized in the chemical processes for urea, salicylic acid, carbonates, polycarbonates, polyurethane, and CO etc., which were mainly low energy exchange processes but the uses of those chemicals are not large amounts. Serious problem is: many chemicals and fuels from CO2 could be prepared by using hydrogen as a reductant though reductive high energy exchange processes. These productions of chemicals and fuels mostly suffer from the high cost of hydrogen, which could be provided mainly by the high temperature reforming processes with lower hydrocarbons.
