Abstract

Ultrathin silica-based nanosheets with a thickness of ∼1 nm are fabricated in a low-cost and high-yield system excluding alkali metal ions. Unlike the Na-zeolites with a long capillary and microporous structure, the ultrathin nanosheets exhibit highly effective surface and active sites. As a result, the 0.4 wt% Pt-loaded nanosheets exhibit superior catalytic activity in H2O2 decomposition with an O2 evolution rate of 342.5 mL g−1 min−1 in a clean aqueous system. © 2011 The Royal Society of Chemistry.
