Conference Alert: 23rd North American Catalysis Society Meeting

“Both optimists and pessimists contribute to our society. The optimist invents the airplane and the pessimist the parachute.” -- G. B. Stern (British novelist)

The 23rd North American Catalysis Society Meeting (http://www.cvent.com/events/23rd-north-american-catalysis-society-meeting/event-summary-7114a9bbbfdf406c83b519c6d26af8e0.aspx) is scheduled for June 2- 7, 2013.

There is good reason to visit the URL listed above, beyond the obvious one of finding out how to register for the event.  The site has a multitude of very informative extended abstracts (https://nam.confex.com/nam/2013/webprogram/), like the one below …

Introduction
Transition metal phosphides show excellent promise for hydrotreating reactions and the most active phosphides, Ni2P and Ni-rich bimetallic phosphides, have exhibited higher HDS and HDN activities than commercial sulfided Co-Mo and Ni-Mo catalysts [1,2]. Oxide-supported metal phosphide catalysts are most often prepared by temperature-programmed reduction (TPR), in which phosphate-like precursors are heated in flowing hydrogen to a maximum temperature in the range 823-923 K. TPR methods do not enable size and shape control of the degree needed to probe microstructure-reactivity relationships in transition metal phosphides. In this study, the preparation, characterization and hydrodesulfurization (HDS) properties of mesoporous silica encapsulated metal phosphide nanoparticles (Ni2P, Pd5P2) having narrow polydispersity were investigated.
Significance
Encapsulation of metal phosphide nanoparticles to form core-shell structures (e.g. Ni2P@mSiO2) minimizes sintering of the nanoparticles and enables probing of the microstructural properties of metal phosphide catalysts under the harsh reaction conditions relevant to industrial hydrotreating processes
