Abstract
AbstractInvited for the cover of this issue are the groups of Joanna Aizenberg and Cynthia M. Friend from Harvard University, Cambridge, USA. The image depicts a templated silica matrix decorated with AuAg nanoparticles catalyzing the oxidative coupling of methanol to form methyl formate.

Highlights
A highly modular synthesis of designed catalysts with controlled bimetallic nanoparticle size and composition and a well-defined structural hierarchy is demonstrated
We demonstrate a modular and versatile approach for the design of an efficient bimetallic catalyst system based on the synthesis of a porous framework of silica with embedded bimetallic AgAu nanoparticles of uniform size and composition
This specific system establishes that catalytic activity and selectivity observed in support-free nanoporous Ag3Au97 alloys[1a, 3-4] translates to the embedded nanoparticles; demonstrating that the modular synthesis process can be used to more generally test design principles
