Dr. Anderson is distinguished for his work on the adsorption and reaction of gases at the surfaces of metals. He has shown that catalysis is not restricted to the surface and is akin to metal tarnishing. Particular studies have shown the fundamental role of carbon-metal bonds in the important catalytic reactions of petrochemical industry. His work has demonstrated the complete inadequacy of the current D-band theory and emphasized the importance of surface impurities. Through the use of ultra-thin films he has demonstrated the changes wrought in catalyst as well as in the gaseous adsorbent.
