Template‐Directed Rapid Synthesis of Pd‐Based Ultrathin
We report a template‐directed strategy for rapid synthesis of Pd‐based (PdM M=Pb Sn and Cd) ultrathin porous intermetallic nanosheets (UPINs) with tunable sizes. This strategy uses preformed seeds which act as the template to control the deposition of foreign atoms and the subsequent interatomic diffusion.

Synthesis of Porous Carbon Monoliths Using Hard Templates
The preparation of porous carbon monoliths with a defined shape via template-assisted routes is reported. Monoliths made from porous concrete and zeolite were each used as the template. The porous concrete-derived carbon monoliths exhibited high gravimetric specific surface areas up to 2000 m2·g−1. The pore system comprised macro- meso- and micropores.

May 19 2014 · Although MOMs have been studied for over 60 years the porous nature of MOMs was not systematically and widely explored until the early 1990 s. This may be one of the reasons why template-directed synthesis of MOMs remains relatively underexplored especially when compared to other classes of porous material (e.g. zeolite and mesoporous silicates).
