Ryoo Ryong FRSC (born 1955[1]) is a distinguished professor of chemistry at KAIST in Daejeon, South Korea.

He obtained the KOSEF Science and Technology Award in 2001 for his work on the synthesis and crystal structure of mesoporous silica.

Because of the potential of this to streamline the gasoline refining process, it was greeted as a "magical substance" by the South Korean press.

He developed a hard-templating synthesis strategy toward nanoporous carbon material and its application to the research field of fuel cells.

In 2011, he extended the surfactant-directing synthesis strategy to various nanoporous structures such as hexagonal honeycomb and disordered nanosponge, rather than lamellar-type nanosheet, and reported these results in Science (2011).

In 2007, Ryoo was named National Scientist of the Republic of Korea and has received research funds as part of the award.
