Turning waste and cheap natural resources into useful chemicals depends on understanding the reactions that happen at the surfaces of solid materials. The lab's two projects take this question in different directions.

Fields

Chemistry

Engineering

Earth & Environmental Science

Topics

struvite

slow-release fertilizer

wastewater valorization

Grants
2 known grants, through Jul 2027

What they work on

  1. Synthesize struvite microcrystals with tailored iron content and characterize their chemical composition and physical properties, to predict how this wastewater-derived fertilizer behaves in the environment.
  2. Measure how struvite colloids with varying iron content photocatalytically transform laboratory stand-ins for dissolved organic matter in aquatic mixtures.
  3. Determine how catalyst surfaces generate radicals during oxidative coupling of methane, and whether surface or gas-phase reactions control selectivity, using vacuum-ultraviolet photoionization mass spectrometry at Sandia.
  4. Feed surface and gas-phase kinetic data into reactor design models to identify catalyst and reactor designs that convert methane selectively to ethane and ethylene, with a thousand-hour industrial catalyst durability test.

More about the research

One looks at struvite, a mineral fertilizer recovered from wastewater, and what reactions it drives in natural waters. The other looks at catalysts that could turn methane, the main part of natural gas, into more valuable hydrocarbons.

Why it matters

The struvite work could guide how wastewater-derived, slow-release fertilizers are engineered and managed. This may help farmers use them while limiting problems such as water eutrophication, the overgrowth of algae caused by excess nutrients. The methane work could help make OCM practical, offering a more efficient, lower-carbon way to turn natural gas into ethylene and other valuable chemicals for the energy and chemical industries.
