This CWA describes a one-pot synthesis method to produce nanocatalysts composed of metallic (Pt-Sn) nanoparticles adsorbed on the surface area of a porous support.
These nanocatalysts are used for the non-oxidative dehydrogenation of alkanes (saturated hydrocarbons) to obtain light alkenes (olefins) and aromatic hydrocarbons.
NOTE 1 Methodology and descriptions in this document are suitable to laboratory scale.
NOTE 2 Safety aspects are not included in this document. General laboratory safety and related nanosafety measures from suitable national or international standards, regulations or literature should be applied.
