Effect of Potassium on Sol-Gel Cerium and Lanthanum Oxide
... Therefore, the catalysts used in the catalytic combustion of soot must be capable of presenting catalyst activity at low temperatures [10]. An important number of catalytic formulations have been developed in this field, including oxides [11]-[14], perovskites [9] [15]-[17], spinels [18] and metals ...

... reaction.4 At room temperature, scandium metal turns a light yellow or pink color in air.1 It is not obvious what is causing the color as Sc3+ would be expected to be colorless (white) due to the lack of d-electrons. Purification and Properties The most interesting thing about these two elements is ...
