Astronut, scientific journals such as the one you quote from are not good sources in general when it comes to physical chemistry data. Are you sure you are not actually quoting for some other physical property relating to titanium oxide? Looking at your source this looks highly likely. "Plasma Nitriding of Titanium Particles in a Fluidized Bed Reactor at a Reduced Pressure from the Journal of the American Ceramic Society" WHAT........!!?? COME AGAIN.......!!??
According to the CRC Handbook of Chemistry and Physics, 75th Edition, the bond energy of Ti-O is 672.4 kJ/mol. This is equivalent to 6.98 eV. To convert to electronvolts you divide 672,400 by 6.022 x 10exp23 (the Avagadro constant which is the total number of molecules in a mole) and then divide this by the total energy is a single electronvolt which is 1.6 x 10exp-19 joules.
You see titanium oxide is not such a strong bond after all and would easily be broken up by the Sunís UV rays.
