Photo 1
Photos of high-throughput reactor showing A) reactor with common headspace top plate (used for catalyst reduction) and B) reactor with isolated headspace plate (used for reaction and gas chromatograph analysis).

Photo 2
Scanning electron micrographs of Raney-NiSn catalyst after reduction at 260 degrees Celsius (Scale bar is 1000 nanometers, inset is magnified 6 X the outer panel).

Photo 3
Scanning electron micrograph of the Raney-NiSn catalyst after reduction at 260 degrees Celsius in H2 (hydrogen gas) and subsequent passivation (slow exposure to air, so the catalyst does not rapidly oxidize) (scale bar is 10 microns).
