About This Topic
The current challenges that modern chemistry faces nowadays are closely related to the need of designing chemical processes that are efficient and environmentally friendly. On one hand, these systems are usually demanded to obtain complex and sustainable organic molecules such as drugs, dyes and biosurfactants. In addition, there is a global need for clean energy sources, which could be fulfilled by massive hydrogen production and high-quality biofuels. In order to achieve these goals catalysis is an indispensable tool. During the last decades homogeneous catalysis blossomed as an efficient way to achieve selective transformations. However, catalyst recyclability and separation remained as a main drawback. In this context, catalytic heterogeneous systems emerged as a cleaner and more effective alternative. In particular, reticular materials appeared as a family of structures that allowed to apply into heterogeneous systems the concepts previously developed for molecular catalysts. At this point, the close interplay between homogeneous and heterogeneous catalytic systems can offer solutions in the areas of electrocatalysis, photocatalysis or enantioselective catalysis.
We call for all types of manuscripts, including original research articles, (mini) reviews, perspectives, and brief research reports in the areas of hetero/homo-geneous catalysis, including but not limited to the following themes:
Manuscript Submission Information
Manuscripts should be submitted through the LIDSEN Submission System. Detailed information on manuscript preparation and submission is available in the Instructions for Authors. All submitted articles will be thoroughly refereed through a single-blind peer-review process and will be processed following the Editorial Process and Quality Control policy. Upon acceptance, the article will be immediately published in a regular issue of the journal and will be listed together on the special issue website, with a label that the article belongs to the Special Issue.

Enhancement of Fischer-Tropsch Synthesis by Periodical Draining of the Wax-Filled Pores of a Cobalt Catalyst by HydrogenolysisAbstract Fischer-Tropsch reactors operated in a steady state suffer from a low pore effectiveness factor and a high methane selectivity caused by internal mass transfer limitations due to the accumulation of long-chain hydrocarbons inside the catalyst pores. Therefore, an alternating process switching between Fischer-Tropsch synthesis (FTS) and drainag [...] |

Abstract In this study, we investigated the oligomerization mechanism of the Fischer-Tropsch synthesis catalyzed by a cobalt-based catalyst supported by SBA-15. The Co/SBA-15 catalyst contained 20% w/w of cobalt. It was prepared by the wet impregnation method and characterized by X-ray diffraction (XRD), N2 adsorption-desorption [...] |
