Au/Ti02 formed by laser vaporisation of gold onto anatase suffered from low activity because the gold content was only 0.02%.13,28 The World Gold Council Au/TiC>2 catalyst performed better, showing 70% selectivity at 80% conversion (353 K).

Chris Corti and the World Gold Council for their interest and support. We feel confident that readers will find the contents useful in their research and in finding new applications for catalysis by gold. 

The World Gold Council has estimated that about 140,000 short tons (about 125,000 metric tons) of gold has been mined throughout history. Of that amount, about 10 percent has been used for industrial, research, health, and other dissipative uses. Dissipative means that the gold was gone once it was used. It was made into devices that were evenmally thrown away. The gold could not or was not recovered from the devices.
