Catalysts support is essential for nanostructured noble metal catalysts activity and stability since that interaction between the metal particle and the support can affect metal particle size and dispersion. Over the last few decades, the most popular catalysts supports are carbon based materials: Vulcan XC-72 carbon black (CB), multi-walled carbon nanotubes (MWCNTs) and graphene. However, their cost-effective production remains a challenge since most of these materials are obtained by pyrolysis of coal or petroleum. Not less negligible is their negative impact on the environment during synthesis because these processes include release of carbon dioxide and other harmful organic products into the atmosphere. Applications of bacterial nanocelluloses as a catalyst support has attracted a great attention since it can be easily synthesized and is an inexpensive, biodegradable, sustainable and green material. Bacterial nanocellulose (BNC) was produced utilizing the Komagataeibacter medellin...ensis ID13488 strain. Stable Pt nanoparticles supported on BNC (Pt/BNC) have been synthetized from a precursor solution of H2PtCl6 by microwave assisted polyol procedure. Catalytic activity was tested for methanol oxidation reaction in sulfuric acid solution. The Fourier transform infrared spectroscopy was used to confirm the structure of bacterial nanocellulose as well as after synthesis of Pt-BNC catalyst. Coupled differential scanning calorimetry (DSC) / thermogravimetric (TG) analysis revealed no loss of platinum during synthesis process. XRD analysis showed characteristic peaks for fcc crystalline structure of Pt/BNC and particle size of 1,7 nm. The activity of the Pt/BNC, catalyst for methanol oxidation was evaluated from potentiodynamic measurements in 0.5 M H2SO4 + 0.5 M CH3OH solution. The results obtained indicate enhanced catalytic activities for methanol oxidation reaction.
Podloge katalizatora imaju veoma važnu ulogu tokom sinteze katalizatora sa plemenitim metalima obzirom da od njihove interakcije sa metalom zavisi veličina čestica i njihova disperzija tokom procesa sinteze. Tokom poslednjih nekoliko decenija kao najčešće korišćene podloge za platinske katalizatore su korišćene podloge na bazi uglljenika: ugalj razvijene površine (Vulcan XC), ugljenične nanotube ili grafen. Međutim, proces dobijanja ovih materijala ima visoke cene zbog toga što se za njihovo dobijanje koriste procesi pirolize uglja ili nafte. Ništa manje zanemarljiv je i negativan uticaj ovih procesa na okolinu pošto procesi sinteze uključuju oslobađanje ugljen dioksida i drugih štetnih materija u atmosferu. Primena bakterijskih nanoceluloza kao nosača katalizatora privukla je veliku pažnju jer se mogu lako sintetizovati i predstavljaju jeftin, biorazgradiv, održiv i zeleni materijal. Bakterijska nanoceluloza (BNC) proizvedena je upotrebom soja Komagataeibacter medellinensis ID13488. S...tabilne Pt nanočestice suspendovane na BNC (Pt/BNC) sintetizovane su iz prekursorskog H2PtCl6 rastvora poliol postupkom uz pomoć mikrotalasne pećnice. Ispitivana je katalitička aktivnost reakcije oksidacije metanola u rastvoru sumporne kiseline. Infracrvena spektroskopija Fourierove transformacije je korišćena za potvrdu strukture same bakterijske nanoceluloze, kao i nakon sinteze Pt-BNC katalizatora. Diferencijalna skenirajuća kalorimetrija (DSC) / termogravimetrijska (TG) analiza nije otkrila gubitak platine tokom procesa sinteze. XRD analiza pokazala je karakteristične vrhove za fcc kristalnu strukturu Pt/BNC i veličinu čestica od 1,7 nm. Aktivnost Pt/BNC, katalizatora za oksidaciju metanola, procenjena je iz potenciodinamičkih merenja u 0,5 M H2SO4 + 0,5 M CH3OH rastvoru. Dobijeni rezultati ukazuju na pojačanu katalitičku aktivnost reakcije oksidacije metanola.
