Abstract Hierarchical zeolites are regarded as promising catalysts due to their well‐developed porosity, increased accessible surface area, and minimal diffusion constraints. Thus far, the focus has been on the creation of mesopores in zeolites, ho

Methane-to-chemicals: a pathway to decarbonization

Autor: Nikolai Nesterenko, Izabel C Medeiros-Costa, Edwin B Clatworthy, Hugo Cruchade, Stanislav V Konnov, Jean-Pierre Dath, Jean-Pierre Gilson, Svetlana Mintova

Publikováno v: National Science Review.

The utilization of methane for chemical production, often considered as the future of petrochemistry, historically could not compete economically with conventional processes due to higher investment costs. Achieving sustainability and decarbonization
