Metalized plastic substrates, and methods thereof are provided herein. The method includes providing a plastic having a plurality of accelerators dispersed in the plastic. The accelerators have a formula AMxByOz, in which A is one or more elements selected from groups 10 and 11 of the Element Periodic Table; M is one or more metal elements in three plus selected from the group consisting of Fe, Co, Mn, Al, Ga, In, Tl, and rare earth elements; and O is oxygen; and x=0-2, y=0.01-2; z=1-4; and the accelerators further have a formula A′M′mOn, in which A′ is one or more elements selected from groups 9, 10, and 11 of the periodic table; M is one or more elements selected from the group consisting of Cr, Mo, W, Se, Te, and Po; and O is oxygen; and m=0.01-2; n=2-4. The method includes the step of irradiating a surface of plastic substrate to expose at least a first accelerator. The method further includes plating the irradiated surface of the plastic substrate to form at least a first metal layer on the at least first accelerator, and then plating the first metal layer to form at least a second metal layer.
