Catalyst engineering! Controlled thermal treatment with N 2 O affords easy active‐site engineering of the Cr II /SiO 2 Phillips catalyst, overcoming some of the structural problems limiting ethylene polymerisation activity and leading to a large increase in the initial rate of polymerisation at room temperature (see figure). The results may be highly relevant to the production of some varieties of polyethylene.
