The Pd/ZrO2 nanocatalyst is demonstrated to be a very efficient catalyst in Heck, Ullmann, and Suzuki reactions of aryl halides in water. The catalyst efficiency is attributed to the stabilization of Pd nanophases provided by tetra(alkyl)- ammonium hydroxide, which behaves both as base and PTC (phase transfer catalyst) agent. %K C-C coupling %K palladium %K colloids %K green chemistry %K nanocomposite catalysts %U http://www.mdpi.com/1420-3049/15/7/4511
