TLDR
In this article, the aldol condensation of acetone was studied over solid base catalysts such as Ca(OH)2, La(OH), ZrO2 and CeO2 in the vapor phase over the temperature range 473-673 K. The reactions were carried out by means of a micropulse reactor, which was directly connected to a GC/MS system.About:

X-ray photoelectron spectroscopy and heterogeneous catalysis, with elimination reactions as an example
TL;DR: In this paper, the authors used XPS to estimate the EPA and EPD strength of catalytically active surface sites and to predict the selectivity of catalysts, and showed that the tendency of spinels to an E2 mechanism is higher than that of alumina.
