A need for NO: Moderating the thermal decomposition of supported nitrates with NO (see picture, center) prevents precursor mobility and is a versatile method for the preparation of small NiO (left; compared to the product of the conventional procedure, right) and Co3O4 particles. These materials can be used as heterogeneous catalysts and show good activity in the Fischer–Tropsch synthesis.
