[22] In addition, Tour has conducted research on the synthesis of graphene oxide,[23][24] its mechanism of formation,[25] and its use in capturing radionuclides from water.

[27] His group has also developed the use of porous metal structures to make renewable energy devices including batteries and supercapacitors, as well as electronic memories.

[31] Tour was the first to show that Feringa-based motors[32] can be used to move a molecule on a surface using light[33] as opposed to electric current from an STM tip.

[34] Tour has also been involved in scientific outreach, such as NanoKids, an interactive learning DVD to teach children fundamentals of chemistry and physics.

[35] In the Scientific American article "Better Killing Through Chemistry",[36] which appeared a few months after the September 11 attacks, Tour highlighted the ease of obtaining chemical weapon precursors in the United States.

Tour is on the board and working with companies including Weebit (silicon oxide electronic memory),[37] Dotz (graphene quantum dots),[38] Zeta Energy (batteries),[39] NeuroCords (spinal cord repair),[40] Xerient (treatment of pancreas cancer), LIGC Application Ltd. (laser-induced graphene),[41] Nanorobotics (molecular nanomachines in medicine),[42] Universal Matter Ltd. (flash graphene synthesis),[43] Roswell Biotechnologies (molecular electronic DNA sequencing),[44] and Rust Patrol (corrosion inhibitors).

[45] Tour's lab's research into graphene scaffolding gel has been shown to repair spinal cords of paralyzed mice.

[58] Tour said his signature only reflected his "personal doubts" on how random mutations happen at the molecular level and that religion "plays no part" in his work.
