In this research, a bench-scale installation was tested for the heterogeneous electro-Fenton treatment of clofibric acid. The setup consists pressurized flow-through electrochemical cell equipped with catalyst fluidized-bed and aerated jet mixer. novelty research is two-fold: use pressurized-jet aerator on an it one first studies combining pressure catalysis in electro-Fenton. Moderate relative...

In order to help the introduction on the automotive market of polymer electrolyte fuel cells (PEFCs), it is mandatory to develop highly performing and stable catalysts. The main objective of this work is to investigate PtNi/C catalysts in a PEFC under low relative humidity and pressure conditions, more representative of automotive applications. Carbon supported PtNi nanoparticles were prepared ...

Development of a highly durable, fuel-tolerant, metal-free electro-catalyst for oxygen reduction reaction (ORR) is essential for robust and cost-effective Anion Exchange Membrane Fuel Cells (AEMFCs). Herein, we report the development of a nitrogen-doped (N-doped) hierarchically porous carbon-based efficient ORR electrocatalyst from protein-rich pulses. The process involves 3D silica nanoparticl...

Catalyst-coated carbon electrodes require two preparation stages: electrode assembly using and polymeric binders subsequent catalyst immobilization on the porous carbons electrode. Such conventional coating methods several steps, which is time-, chemical-, energy-consuming. Also, can impair porosity block catalytic sites of final electrodes. This study introduces a novel one-pot synthesis metho...

Summarization of electronic discussion fora is a unique challenge; techniques that work startlingly well on monolithic documents tend to fare poorly in this informal setting. Additionally, conventional techniques ignore much of the structures that have the potential to serve as valuable features in the summarization task. We present several novel examples of such features, including the catalys...

We have compared the electrocatalytic activity of several substituted and unsubstituted Co and Fe N4-macrocyclic complexes (MN4) for the electro-reduction of oxygen with the complexes directly adsorbed on the edge plane of pyrolytic graphite or adsorbed on carbon nanotubes (CNTs). In the presence of CNTs, one order of magnitude higher surface concentrations of MN4 catalysts per geometric area u...

Activated-carbon-fiber cloth (ACFC) [ 1-5] has promising characteristics as an adsorbent, and potentially as a molecular sieve, a catalyst, or a catalyst support for a wide range of concentrations and chemical species. This is mainly because ACFC can be prepared with different and controlled pore size distributions, total pore volumes, specific surface areas and surface chemistries. ACFC can be...
