We prepared stable Ag/Pd colloids to be used as both SERS-active and catalytic platforms by combining pulsed laser ablation of Ag in pure water and galvanic replacement with a successive addition of Pd(II) nitrate. Beyond UV–vis absorption and microscopic characterization, we also performed XPS test...
