In catalysis, physical adsorption of gas molecules on a solid surfaces is an important technique to determine the surface area of a material as well as its porosity. We count with a Micrometrics ASAP 2010 system to peform BET measurements.

Tacking hydrophobic organosilyl groups onto the surface of a common zeolite helps overcome the catalyst’s inability to function effectively when liquid water is the reaction medium, chemical engineers have found. The researchers believe their water-repelling zeolite could be a hit for high-pressure water/oil emulsion processing of biomass into fuels and chemicals. The protecting group strategy could also benefit other types of catalysts that are inhibited by water, they say.
