APS -APS March Meeting 2017 - Session Index MAR17

Currently, use of metal alysts is the most popular method of performing this reaction on a large scale. These metal alysts usually require high-temperature and/or high-pressure reaction conditions, and produce hazardous chemicals. This has led to a call for more environmentally friendly nonmetal alysts.

Allotropes of boron

Boron (likely mixed allotropes) Boron can be prepared in several crystalline and amorphous forms. Well known crystalline forms are α-rhoohedral, β-rhoohedral, and β-tetragonal. In special circumstances, boron can also be synthesized in the form of its α-tetragonal, and γ-orthorhoic allotropes. Two amorphous forms, one a finely divided powder and the other a glassy solid, are also known.
