Recent Trends

An overview of analytical methods currently used for the determination of pesticide residues in water samples is presented. As liquid chromatography and gas chromatography, coupled to mass spectrometry, are considered to be the most appropriate techniques for determination of pesticides in environmental waters, the most recent developments and applications in this field are discussed, as well as the extraction procedures employed for analyte isolation and preconcentration.

Abstract Recent progresses in proton exchange membrane fuel cell electrocatalysts are reviewed in this article in terms of cathodic and anodic reactions with a focus on rational design. These designs are based around gaining active sites using model surface studies and include high-index faceted Pt and Pt-alloy nanocrystals for anodic electrooxidation reactions as well as Pt-based alloy/core–shell structures and carbon-based non-precious metal catalysts for cathodic oxygen reduction reactions (ORR). High-index nanocrystals, alloy nanoparticles, and support effects are highlighted for anodic catalysts, and current developments in ORR electrocatalysts with novel structures and different compositions are emphasized for cathodic catalysts. Active site structures, catalytic performances, and stability in fuel cells are also reviewed for carbon-based non-precious metal catalysts. In addition, further developmental perspectives and the current status of advanced fuel cell electrocatalysts are provided. Graphical Abstract
