  • Non-metal doped metal oxides formed using flame spray pyrolysis
    Patent number: 11739002
    Abstract: Methods of forming non-metal doped metal oxide nanoparticles using a flame spray pyrolysis process are described. The non-metal doped metal oxide nanoparticles exhibit high photocatalytic activity. Specific non-metal doped metal oxides nanoparticles which can be formed by the described processes include nitrogen-doped titanium dioxide and sulfur-doped titanium dioxide.
    Type: Grant

  • Sulfur tolerant highly durable COsorbents
    Patent number: 8114808
    Abstract: A sorbent for the capture of carbon dioxide from a gas stream is provided, the sorbent containing calcium oxide (CaO) and at least one refractory dopant having a Tammann temperature greater than about 530° C., wherein the refractory dopant enhances resistance to sintering, thereby conserving performance of the sorbent at temperatures of at least about 530° C. Also provided are doped CaO sorbents for the capture of carbon dioxide in the presence of SO2.
