Preparation of Glassy Metals for Catalytic Studies

The various metallic glasses reported in the literature [4.9] fall into a few well-defined categories (i) late transition metal + metalloid (ii) early transition metal + late transition metal or group IB metal (iii) earth alkali metal + group IB metal (iv) early transition metal + alkali metal and, (v) Actinide + early transition metal. In catalysis research, exclusively metallic glasses of categories (i) and (ii) have been used so far. Table 4.1 lists glassy metals which have been used in catalytic studies. Note that metal-zirconium alloys and Ni, Fe, and mixed Ni-Fe alloys with P and/or B as metalloid have been used most frequently.
