Construction of uniform ZrO2 nanoshells by buffer solutions†
Abstract
We identified that the growth kinetics of ZrO2 could be well-tuned in a CH3COOH–CH3COONa based buffer solution, which provided an efficient way to build uniform ZrO2 nanoshells on various substrates. Using this synthetic strategy, yolk–shell structured Pd@ZrO2 is demonstrated as a promising catalyst for methane oxidation.
