Abstract

A renewable production of hydrogen would enable the further development of carbon-dioxide emission-free vehicles. Ethanol reforming is a very promising lead which necessitates nanocatalysts. We propose here a method to embed nanocatalysts in porous microbeads and thus facilitates their use. We developed a microfluidic chip enabling a sharp temperature gradient to generate in-drop phase separation and template porous microbeads. Using this chip, we produce microbeads of around 50 μm diameter, with pores of the order of 1 μm in which nanoparticles are embedded.
