CFI Investment Supports One-Of-A-Kind Catalysis Research

The Canadian Foundation for Innovation has given funding of $7,721,387 for the University's Centre for Catalysis Research and Innovation (CCRI). The project's total budget is $19,306,758. The main object of the research project, headed by Professor Abdel Sayari, is to accelerate the discovery of new catalytic processes and develop selective catalysts. The discovery of new catalytic processes will, among other things, minimize the environmental impact of chemical processes: If the process can be made more efficient, there are fewer by-products and therefore less chemical waste. The project implements high throughput strategies using equipment found in no other academic lab in the world. The Centre's research will focus on pharmaceuticals, fuel cells and the catalytic oxidation of pollutants in wastewater.
