Moreover, approximately 90 percent of all industrial chemicals produced in the world use catalysts within the manufacturing process. Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well. Carbon makes up only about 0.025 percent of Earth's crust. Catalysis is a multidisciplinary area of chemistry, particularly industrial chemistry where around 85% of all products pass through at least one catalytic stage. In order to understand the challenges facing the application of catalysts in the fine chemicals industry, one has to recognize not only the essential industrial requirements but also how the process development is carried out, and which conditions determine the suitability of a best catalyst [1,2]. in the production of catalysts on their own technologies or as toll manufacturers.
