Catalysts

ALD NanoSolutions has been working on improving catalyst powders and particles with industry leaders in the field.  In many processes, catalyst performance could be improved by the use of nanoscale metal sites which are either better stabilized or better controlled.  ALDN’s proprietary technology takes advantage of gas phase atomic layer deposition (ALD) chemistries to produce novel catalysts.

ALD techniques have the potential to minimize noble metal loading and maximize dispersion.  We have developed a technique to create a porous structured net to reduce the sintering of catalysts and thus improve their lifetime performance. We can also design and produce multi-metal catalysts with control over the amount of metal and the dispersion of the metal on the catalyst support.  In addition, interesting structures such as alloys or stacked metals may be possible by this technique.

Effect of Annealing Temperature on Pt Stabilization

Porous net provides “pinning” effect to stabilize catalysts used at high temperatures decreasing catalyst mobility while maintain catalytic activity.
