DENVER, March 23, 2015 -- What many people might call the daily laboratory grind Theodore Betley, Ph.D., calls play. As a student, he developed a passion for lab work that could now pay off for the rest of the world. Today, he will present pioneering work that could help turn greenhouse gases into useful products during "The Kavli Foundation Emerging Leader in Chemistry Lecture" at the 249th National Meeting & Exposition of the American Chemical Society (ACS).

ACS, the world's largest scientific society, is holding the meeting here through Thursday. It features nearly 11,000 presentations on a wide range of science topics.

"Our goal is to answer the questions: How do you take the sea of gases that makes up our atmosphere and convert that into liquid fuels?" Betley says. "Or how do you remediate greenhouse gases and turn them into something usable for the chemical industry?"

The key to answering these big-picture questions and others is getting a better grasp on how nature works, says Betley, who is a professor of inorganic chemistry at Harvard University.

"Nature has evolved over billions of years to convert nitrogen from the atmosphere into fertilizer or to harness solar energy to split water into oxygen and protons and electrons," he explains. "As chemists, we're trying to catch up in order to do those transformations ourselves."

Inorganic chemists design new catalysts that can spur such transformations along. But it's not an easy task. Betley says the field's top scientists in the 1960s started creating catalytic clusters that copy nature's strategy, relying on several underdog metals rather than just one heavy hitter to get a reaction going.

Betley's lab is now at the forefront of such efforts. They've developed novel materials that are extremely efficient at prompting reactions to take place in the lab. Harnessing the ability to drive and control these reactions could help provide new solutions for reducing levels of greenhouse gases that contribute to global warming. The reactions could remove those gases from the air and turn them into chemical products in high demand that industry now gets in less sustainable ways.

Betley's path toward this potential turning point in the field started when he was an undergraduate student, he says. Through a series of internships in various labs, he developed a near-compulsive desire to understand chemical reactions on a fundamental level.
