Using abundant cobalt and a unique experimental approach to probe ways to speed a sluggish catalytic reaction to harvest hydrogen from water, researchers from Boston College and Yale University ...

Cobalt oxide thin films, principally in the Co₃O₄ spinel phase, have emerged as versatile materials across energy conversion, sensing, optoelectronics and spintronics. Their functionality derives from ...

Structural characterizations for the as-prepared catalysts. (a) XRD patterns of the Co3O4 and 4% Er−Co3O4. (b) Crystal structure of the Co3O4 in this study. (c) TEM image of 4% Er− Co3O4, (d-e) HRTEM ...

Covalent organic frameworks (COFs) are less stable as catalysts than previously thought but remain highly active. COFs are promising designer catalysts, for example for the sustainable production of ...
