Mattson nd his students developed interesting, safe and
convenient methods for generating and manipulating small
gases for classroom demonstrations, laboratory experiments
and study. We have
developed classroom demonstrations and laboratory
for use at a variety of levels ranging from the middle
school and high
school levels up through university-level freshmen
and chemistry majors taking descriptive inorganic
results of this work have been published in a series of
Chem13 News, the Journal of Chemical
Education and in two books. All
together over 150 experiments have been devised for the a
gases including CO2, H2,
O2, N2, NH3, NOx, C2H2, H2S, SO2, Cl2, HCl, CO, C2H4, CH4, and N2O. A
Web page is available.
For the past decade, our focus has shifted to our “gas reaction catalyst tube” developed with students here at Creighton. The current version of the catalyst tube consists of a small glass tube (6 mm diameter x 10 cm) containing ~ 1 mg nanoparticle palladium on alumina support. Always with undergraduate research students, we designed, developed, and published a series of articles on gas-phase catalytic reactions. All along the way, the design of the catalyst tube improved and now can be constructed for about $2 and used indefinitely.
