This study reveals the source of discrepancy between lifetime oxygen evolution reaction (OER) catalysts determined by rotating disk electrode (RDE) measurements vs that obtained in a membrane assembly (MEA) an electrolyzer. We show accumulation microscopic bubbles pores electro-catalyst layer during OER takes place both RDE and MEA measurements. However, this was found to be much more significa...

Heterogeneous photo-electro-Fenton process is an attractive technology for the removal of recalcitrant pollutants. To better exploit presence irradiation source, a bifunctional catalyst with TiO2 nanoparticles embedded into iron–chitosan matrix was developed. The catalytic activity improved by optimization loaded content. prepared composite catalysts based on TiO2, Fe3O4 and chitosan were calle...

This paper argues that innovation can be best understood as an information process which is then concretized as a product that meets demand. Two very different firms, Canon Inc. and Apple Computer Inc., are used as case study illustrations. Innovation does not proceed through logical deduction, but rather is furthered by the use of metaphors and analogies. The bureaucratic and staid structures ...

The observation of Manchot? that sodium pentacyano-ammineferroate2 I absorbs oxygen has led Baudisch and his coworkers3 to study the catalytic action of this salt, as well as of its water analogue II, in the oxidation of pyrimidines and purines. The present authors have previously reported in this journal4 on the nature of the oxidation products obtained. In the present paper the problem is con...

Herein, the application of a N-doped graphitic-carbon-coated iron nitride composite dispersed in carbon framework (Fe3N@NG/NC) is investigated as heterogeneous electro-Fenton (HE-EF) catalyst for efficient removal organics. The simultaneous carbonization and ammonia etching iron-based metal organic (Fe-MOF) materials yielded well-dispersed carbon-coated Fe3N nanoparticles with diameter ~70 nm. ...
