Project summary
The proposed project entitled Polymer coated
ordered mesoporous carbons with multifunctional
properties will be developed in Institute of
excellence of the Romanian Academy by a team
formed from the project leader and a tutor with
complementarily expertise required for the
project development, e.g. mesoporous carbons and
polymer science, respectively. The aim of this
research project is to prepare polymer-coverd
ordered mesoporous carbon materials with high
adsorption properties, appropriate for
decontamination of industrial water and
haemoperfusion. The project is organized in three
research phases dealing, respectively, with (a)
the preparation of mesoporous nanoparticles (b)
functionalisation of the particle by chemical
treatment and polymer coating (c)
characterization of structure, physico-chemical
and the sorption properties of the functional
particles. Expected results three ISI papers
six conference presentations.

Project objectives

• - To establish a reproducible method for the
  synthesis of highly ordered mesoporous carbons
  with designed architecture and showing high
  sorption properties
• - To provide a treatment method affording high
  functionality (surface reactivity and
  wettability) of the pore surfaces
• - To optimize the preparation conditions of
  polymer-carbon systems in order to minimize the
  particle agglomeration and to maintain
  appropriate porosity
• - To establish preparation-structure-properties
  correlations and to check the end use properties
  of the optimized materials.

Project selected results

• 2013 synthesis of ordered
• mesoporous carbon

Ordered mesoporous carbon materials were obtained
by template synthesis using SBA-15 silica
template and glycerol as carbon precursor.

Project selected results

• 2014 polymer-coating
• ordered mesoporous carbon

7
Project selected results

• 2014 preliminary application test

The obtained results showed that the adsorption
capacity obtained for PNiPAM-functionalized
mesoporous carbon (80) is greater than the
vitamin B2 adsorption on pristine mesoporous
carbon (53). These results show that the
PNiPAM-functionalized mesoporous carbon compare
favorably with unfunctionalized mesoporous carbon
8
Project selected results

• 2015 sorption tests of creatinine on
  PNiPAM-functionalized ordered mesoporous carbon
  materials

The obtained results showed that the adsorption
capacity obtained for PNiPAM-functionalized
mesoporous carbon (460 mg/g) is greater than that
of pristine mesoporous carbon (390 mg/g). These
results show that the PNiPAM-functionalized
mesoporous carbon are good candidate for
haemofiltration

• 2015 sorptive properties tests on mesoporous
  carbon material coated with polystirene

• three adsorption isotherm models were studied
• the sorption data fitted into Langmuir,
  Freundlich and Temkin isotherms
• the Langmuir adsorption model was found to be
  have the highest regression value and hence the
  best fit

A comparative study have been done, focusing on
ordered mesoporous carbon materials coated with
chitosan and chitosan-coated ferrite. Due to the
greater textural properties of ordered mesoporous
carbon materials, the best sorption capacity for
Cr(III) ions has been obtained.
