He is the son of José Ramón Palacio, a historic player of Olimpo de Bahia Blanca during the 1980s. Palacio holds a Spanish passport, allowing him to be counted as an EU player.

In December 2007, Palacio participated in the 2007 FIFA Club World Cup, playing in Boca Juniors' 1–0 victory over Tunisian club Étoile du Sahel on 12 December. On 16 December, he would score an equalizer to make the score 1–1 against Milan, as the Italian side eventually won 4–2. Palacio earned the Bronze Ball trophy in the tournament, being ranked as the third best player behind Milan players Clarence Seedorf and Kaká respectively. Palacio's performance in the 2008 Copa Libertadores helped Boca avoid elimination from the group stage by scoring twice against Mexico's Atlas in a 3–0 home victory and scoring the third goal in Boca's dramatic 4–3 win against Chile's Colo-Colo. On 7 May 2008, Palacio scored in a 2–1 second-leg win against Brazilian club Cruzeiro. Boca eventually reached the semi-finals, where they would lose to Fluminense.
