AB  - TiO2/carbon    composite    (TiO2/HTC),    synthesized    by    hydrothermal carbonization,  was  characterized  by  thermogravimetric  analysis,  nitrogen adsorption–desorption  isotherms  and  X-ray  diffraction.  The  possibility  of using   TiO2/HTC   as   photocatalysts   for   UV   and   visible   light   assisted degradation  of  methylene  blue  inaqueous  solution  was  examined.  It  was found  that  carbon  presence  in  TiO2/HTC  leads  to  the  higher  porosity  and increase in the share of photocatalytically active anatase phase. Compared to the   hydrothermally   synthesized   TiO2,   TiO2/HTC   showed   the   superior photocatalytic  activity  under  UV  irradiation.  In  addition,  TiO2/HTC  show high  recycling  ability  with  degradation  ratio  of  methylene  blue  higher  than 81%  after  five  cycles.  Also,  TiO2/HTC  is  expected  to  be  a  promising candidate for photocatalytic processes using visible light.

AB  - Activated carbon obtained by carbonization and activation of waste hemp
fibers was used as an efficient, low-cost sorbent for pesticide removal. Data
obtained from batch and continuous process of pesticide adsorption was
used for development of the mathematical model that describes the
phenomenon of pesticide transport through the porous sorbent matrices.
Effective diffusion coefficient and the pesticide concentration profile within
the activated hemp fibers, obtained as results of proposed model, give the
insight in the mechanism and the rate of adsorption process and pesticide
transport through the sorbent. A good agreement between model prediction
and the experimental data indicates that the proposed mathematical model
can be successfully used for optimization and selection of appropriate
adsorption process for pesticide removal.

AB  - Structural and surface characterization of pristine and boron doped
carbonized hydrothermal carbons (CHTC) is reported. Boron was
introduced into glucose precursor solution with concentration of 0.2% and
1%. Following hydrothermal treatment, samples were carbonized to 1000oC
and examined by Raman spectroscopy and temperature programmed
desorption. Characterization of obtained samples as material for carbon
paste electrode was performed by cyclic voltammetry measurements of the
Fe (CN)6
3-/4- redox couple. Structural analysis showed that lower boron
content in precursor solution induced structure ordering, while higher
amount of boron caused structural disorder of CHTC sample. Boron
presence in CHTC samples reduced number of surface active sites for
oxygen adsorption and consequently improved their electrochemical
response as electrode material for carbon paste electrode.
