Summary: In this study, the addition of Rh to Pd-based materials was found to enhance the electrooxidation activity of ethanol and glycerol. Physicochemical characterizations of the synthesized PdxRhy/C materials showed close bimetallic compositions to the targeted values, with particle sizes in the nanometer range. The PdxRhy/C catalysts exhibited increased carbonate production in ethanol oxidation and lower onset potential in glycerol oxidation, selectively producing glycerate and tartronate.

Summary: Transition metal sulfides (NiSx, MoSx and Ni0.5Mo0.5Sx) were synthesized and their HER performance was evaluated. The presence of nickel oxide on the surface of Ni0.5Mo0.5Sx was found to enhance water dissociation, while molybdenum sulfide catalyzed the reduction of adsorbed hydrogen species. When mixed with Carbon Vulcan, Ni0.5Mo0.5Sx showed a slightly higher overpotential compared to 40% Pt/C.

Summary: Electrodeposited bismuth ferrite (BiFeO3) thin films were used as photoanodes for the photoelectrocatalytic degradation of methylene blue. The morphology, thickness, and optical properties of the films were characterized by XRD, FESEM, and UV-vis spectroscopy. The photoanodes showed increased band gaps and improved photocurrent response with shorter electrodeposition times. The removal of methylene blue showed higher degradation rates with shorter electrodeposition times. The electrodeposition process with citric acid improved electrode stability and reduced catalyst leaching.

Summary: The aim of this study is to examine the proof of concept for the gamma-radiolysis-assisted direct growth of monometallic gold and bimetallic gold-silver nanostructured particles. We revised the gamma radiolysis procedure to generate free-standing Au and Au-Ag nano- and micro-structured particles onto a gas diffusion electrode by the immersion of the substrate in the reaction mixture. The developed strategy can be easily extended to the synthesis by radiolysis of other types of ready-to-use metal electrocatalysts as advanced electrode materials for heterogeneous catalysis.

Summary: In this study, N-HNT-TiO2 composite nanofibers were produced by combining electrospinning of halloysite with nitriding for acetaminophen photodegradation. The materials showed even distribution of nitrogen and exhibited faster photodegradation of acetaminophen under visible light compared to samples without nitrogen. The composite nanofibers maintained their photocatalytic activity after repeated use and OH center dot-, O-2(center dot-) and h(+) radicals were found to play key roles in acetaminophen degradation.

Summary: The glycerol electrooxidation reaction was investigated using Pd/C and PdFe/C catalysts synthesized by the microwave polyol decomposition method. The introduction of iron in the Pd/C catalyst composition improved the catalytic activity and stability. The PdFe/C catalysts exhibited higher oxidative capacity and effectively maintained the glycerol oxidation products. The analysis confirmed the main products to be glycerate, glycolate, formate, tartronate, and oxalate. The study suggests that glycerol has potential as a platform for generating high value-added products and can be utilized as a renewable clean energy source for electrochemical synthesis and fuel cell applications.
