Ordered micro/mesoporous composite prepared as thin films
Article Abstract:
A new synthesis method for preparation of thin films and powders consisting of zeolite beta nanocrystals embedded in ordered mesoporous silica matrix is described. It is shown that the incorporation of beta nanocrystals in the mesoporous silica matrix and the mesophase order itself can be controlled through the variation of the fractional amounts of the zeolite nanoparticles and silica/surfactant solutions.

Structural, chemical and electronic properties of Pt/Ni thin film electrodes for methanol electrooxidation
Article Abstract:
The Pt/Ni thin film electrodes were fabricated by e-beam evaporation of metal layers and rapid thermal annealing (RTA), to achieve alloy formation between the Pt and Ni layers. Among the Pt/Ni catalysts, the Pt-based alloy showed the highest catalytic activity in methanol electrooxidation and the largest shift in the Pt 4f peak in the XPS.
