Adapting biological systems for nanoparticle synthesis opens an orthogonal Green direction in nanoscience by reducing the reliance on harsh chemicals and energy-intensive procedures. This study addresses challenge of efficient catalyst preparation organic synthesis, focusing rapid formation palladium (Pd) nanoparticles using bacterial cells as a renewable eco-friendly support. The catalytically active bacterium Paracoccus yeei VKM B-3302 represents more suitable approach to increase reaction...
N-doped graphene is not only a promising metal-free catalyst, but also convenient carrier of metal nanoparticles for the creation effective catalysts. Graphitic carbon nitride (g-C3N4) used more often in photocatalytic processes and less as electrocatalysts. This paper describes preparation N‑containing composites consisting reduced oxide (rGO) g-C3N4 further metal-carbon catalytic systems. These were prepared by heat treating dry mixtures (GO) melamine (MA) temperature range 450-550 °C air....
• Cu 0,5 Zn Fe 2 O 4 ferrite samples are synthesized by co-precipitation method. Heat treated ferrites prepared with polyvinylpyrrolidone reduced in an electrochemical system. Fe-Cu composites form after the reduction of ferrites. The composite formation is influenced heat treatment and polymer. powders exhibit a high electrocatalytic activity. were from using method without (PVP) followed reduction. phase constitutions morphological features produced Cu-Zn analyzed. thermal stability...
