Our Research Mission

Scientists in Brookhaven's Chemistry Division conduct basic and applied chemical research with an emphasis on new energy conversion pathways.

Primary research subjects include catalysis and electrocatalysis for sustainable fuel synthesis and use, solar energy conversion to fuels, fundamental gas and condensed phase molecular dynamics, radiation chemistry, and advanced chemical separations for energy applications. Fundamental studies of neutrino properties are also conducted in several international collaborations in nuclear and particle physics.

    Catalysis by supported metals is size sensitive, so the size control is extremely important. Here, I will present two examples for the size control of catalysis. One is the size control of gold catalysts by tuning the metal support interaction. In the last decade, we've developed several methods to control the particle size of gold, for example, adding a second metal to form alloy with gold, using the thiolated gold nanoclusters as the precursor of gold catalysts, and so on. The other example focuses on single-atom catalysis that has emerged as a new frontier in heterogeneous catalysis and shown distinctive performances in a series of oxidation and hydrogenation reactions. The ways we developed to stabilize the single atoms will be introduced. The mechanism for the stabilization of the nanoparticles/single atoms were proposed based on the characterization by aberration-corrected HAADF-STEM, in situ EXAFS and DFT calculations.
