Superior catalytic reduction of methylene blue and 4-nitrophenol by copper nanoparticles-templated chitosan nanocatalyst

open access: yesCarbohydrate Polymer Technologies and Applications, 2023
We represent a copper nanoparticle (CuNPs)-templated chitosan (CS) nanocomposite as an effective catalyst for the catalytic reduction of aqueous hazardous organic micropollutants, which was synthesized via a facile in-situ reduction step of pre-chelated ...

3-D Tracking and Visualization of Hundreds of Pt-Co Fuel Cell Nanocatalysts During Electrochemical Aging

open access: yes, 2011
We present an electron tomography method that allows for the identification of hundreds of electrocatalyst nanoparticles with one-to-one correspondence before and after electrochemical aging. This method allows us to track, in three-dimensions (3-D), the
