Abstract
The current document is directed to processes for producing improved porous catalysts for the dehydrogenation of organic compounds. In one implementation, the process comprises providing a powder of metal particles, sieving the powder using vibrating-screen sieves, aligning metal particles collected from sieving under an external magnetic field, partially sintering the aligned metal particles to form a solid matrix by heating the aligned metal particles in a furnace or microwave oven, or heating the aligned metal particles using a laser sintering process with a controlled amount of external heat, to a temperature below the melting point of the metal powder, and oxidizing the matrix to produce the porous catalyst. The catalysts produced by the disclosed methods have a porous body with increased surface area, can assume various microstructures, and consist essentially of metal oxides.
