Title: The Innovative Contributions of Walter Laessig

Introduction

Walter Laessig is an accomplished inventor based in Gelnhausen, Germany, known for his groundbreaking work in material science. He holds a single patent that showcases his innovative approach to catalyst support and the production of advanced porous carbon materials. His expertise and contributions play a significant role in advancing technologies in various applications.

Latest Patents

Walter Laessig's noteworthy patent pertains to a catalyst support and method for producing porous graphitized carbon material covered with metal nanoparticles. The methodology involves infiltrating a porous template framework made of inorganic material with a carbon precursor. After the thermal treatment of this precursor, the template is removed, resulting in particulate porous carbon materials that are then covered with catalytically active substances. Remarkably, Laessig’s invention allows for a controlled thermal treatment process that starts with carbonization, preventing the premature graphitization of the material until after the template's removal. The resulting graphitized carbon material boasts a sophisticated hierarchical pore structure with a pore volume of at least 0.5 cm/g, predominantly comprising macropores with sizes ranging from 100 to 5000 nm. Prior to the application of the catalytically active substances, the carbon material undergoes an activation treatment in an oxidizing atmosphere, further enhancing its properties.
