AB  - Composites of carbons with metal oxides and metal sulfides have attracted a lot of interestas materials for energy conversion and storage applications. Herein, we report on novel N,O-dopedcarbon/ZnO/ZnS and N,O-doped carbon/ZnO composites (generally named C-(MOF-5/PANI)),synthesized by the carbonization of metal–organic framework MOF-5/polyaniline (PANI) composites.The produced C-(MOF-5/PANI)s are comprehensively characterized in terms of composition,molecular and crystalline structure, morphology, electrical conductivity, surface area, and electrochemicalbehavior. The composition and properties of C-(MOF-5/PANI) composites are dictated bythe composition of MOF-5/PANI precursors and the form of PANI (conducting emeraldine salt (ES)or nonconducting emeraldine base). The ZnS phase is formed only with the PANI-ES form due toS-containing counter-ions. XRPD revealed that ZnO and ZnS existed as pure wurtzite crystallinephases. PANI and MOF-5 acted synergistically to produce C-(MOF-5/PANI)s with high SBET (up to609 m2 g−1), electrical conductivity (up to 0.24 S cm−1), and specific capacitance, Cspec, (up to 238.2 Fg−1 at 10 mV s−1). Values of Cspec commensurated with N content in C-(MOF-5/PANI) composites (1–10 wt.%) and overcame Cspec of carbonized individual components PANI and MOF-5. By acid etchingtreatment of C-(MOF-5/PANI), SBET and Cspec increased to 1148 m2 g−1 and 341 F g−1, respectively.The developed composites represent promising electrode materials for supercapacitors.

AB  - Environmentaly friendly photoelectrochemical (PEC) materals are in the center of the research
interest for sustainable solar-to-chemical energy conversion. Lately, bismuth vanadate (BiVO4)
has attracted attention due to its visible light harvesting properties, band edge positions and lowcost synthesis method. However, BiVO4 has poor charge transfer properties due to the high rate
of electron-hole recombination. It has been shown that metal doping efficiently boosts charge
separation and hence increases PEC water splitting activity. Herein, we report physicochemical
properties of hydrothermaly sinthesized 1%-, 2.5%- and 5%- Cu-doped BiVO4 powders for 8 h
and 20 h. X-ray diffraction (XRD) study indicates that, depending on the degree of doping and
synthesis time, material exists in monoclinic or tetragonal scheelite phase, but mixed phase
composition was also possible. Monoclinic phase was formed in a case of pristine samples
(synthesized for 8 h and 20 h) and 1% and 2.5% doped samples synthesized for 8 h. Tetragonal
phase was observed in case of 5% and 1% doped samples synthesized for 8 h and 20 h,
respectively. In the samples synthesized for 20 h and doped with 2.5% and 5% mixed phase was
noticed. Scanning electron microscopy (SEM) reveals that samples with monoclinic phase
consists of combination of worm-like and prismatic structures while tetragonal samples showed
spherical shape. In case of samples with mixed phase a combination of prismatic and spherical
shape was observed. Local structure was examined with Raman and Fourier Transformed Infrared
(FTIR) spectroscopy. Optical properties were characterized with UV-Vis Diffuse Reflectance
Spectroscopy (DRS) and Photoluminescence (PL) spectroscopy. Monoclinic phase has band gap
in range 2.35 – 2.52 eV while samples with tetragonal phase has band gap in range 2.8 – 3 eV.
Based on the results it can be concluded that band gap is dependent on the phase composition of
samples. PL results indicate that monoclinic samples possess better recombination features than
tetragonal ones. Preliminary measurements confirmed considerable higher PEC activity of lightirradiated samples.

AB  - All remediation pathways in aqueous solutions come down to three dominant ones - physical, chemical, and combinations thereof. Materials proposed for adsorption and oxidative degradation can induce positive or negative effects on cells compared to the pollutants themselves. Present research deals with the effects different methods for pesticide remediation have and how they impact cytotoxicity. With this particular intention, Fe-modified zeolites (obtained via citrate/oxalate complexes) of three zeotypes (MFI, BEA and FAU) were prepared and tested as adsorbents and Fenton catalysts for the removal of the acetamiprid pesticide. The materials are characterized by AFM, FTIR spectroscopy and ICP-OES. A different effect of the zeolite framework and modification route was found among the samples, which leads to pronounced adsorption (FAU), efficient Fenton degradation (MFI) or synergistic effect of both mechanisms (BEA). The cytotoxic effects of acetamiprid in the presence of zeolites, in pristine and modified forms, were tested on the MRC-5 human fibroblast cell line. A complete survey of the toxicity effect behind different pesticide removal methods is presented. Since neither adsorption nor catalytic degradation is the best option for pesticide removal, the focus is shifted to a combination of these methods, which proved to be optimal for pesticide toxicity reduction.
