Special Issue Information

Dear Colleagues,

This Special Issue aims to attract contributions covering the field of two-dimensional (2D) nanomaterials, or more precisely, functionalized 2D nanostructures with advanced catalytic properties. Functionalization of 2D nanostructures prevents (re)aggregation during wet processing and extends the scope of their applications by the incorporation of functional units on their surface/periphery. Over the last decade, an interdisciplinary interest in these unique materials has emerged. In this Special Issue, we intend to provide a platform for experts on the topic to present their latest results dealing with 2D functionalized nanomaterials for energy, environmental, and medical catalytically-driven processes.

The scope of the topics to be covered include but are not limited to the following:

  • 2D nanomaterials
    • graphene, including graphene oxide, reduced graphene oxide, doped-graphene, etc.
    • elemental analogues of graphene, e.g., phosphorenes
    • transition metal dichalcogenides
    • MXenes
    • 2D perovskites
    • 2D polymers
    • 2D MOFs & COFs
  • functionalization
    • covalent functionalization
    • supramolecular/noncovalent functionalization
    • particle growth
    • heterostructures
    • defect engineering
    • doping
  • catalytically-driven applications
    • electrocatalysis
    • photocatalysis
    • organocatalysis
    • thermocatalysis

As Guest Editors, we expect that excellent works on the functionalization of 2D nanomaterials for catalytically-driven processes will be collected in this Special Issue, which will act as a useful tool not only for specialists in the field but also for the broader readership of the journal.

Sulfur-doped carbon nanohorns (S-CNHs) were prepared by an easy one-pot solvothermal process and were employed as efficient electrocatalysts towards water splitting. Initially, oxidation of CNHs followed by thermal treatment with the Lawesson’s reagent resulted in the formation of S-CNHs with the sulfur content determined as high as 3%. The S-CNHs were thoroughly characterized by spectroscopic, thermal and electron microscopy imaging means and then electrocatalytically screened. Specifically, S-CNHs showed excellent activity and durability for both O2 and H2 evolution reactions, by showing low overpotential at 1.63 and −0.2 V vs. RHE for oxygen and hydrogen evolution reaction, respectively. Additionally, S-CNHs showed significantly lower Tafel slope value and lower current resistance compared to oxidized and pristine CNHs for both electrocatalytic reactions. The outstanding electrocatalytic properties and high conductivity, along with the high S-doping level, render S-CNHs a promising bifunctional electrocatalyst for water splitting. Full article
