The metals are preferably provided on a support selected from the group of titania, stabilized titania, zirconia, stabilized zir - conia, silica or mixtures thereof, most preferably zirconia stabilized with tungsten. The reaction with oxygen is carried out at tem a - perature from about 100°C to about 300°C and at a partial pressure of oxygen from about 50 psig (344,74 kPa) to about 2000 psig (13,79 MPa).
