Highly efficient and stable catalytic reactivities of iron(-oxide) incorporated carbide nanofiber composite for environmental and bio-medical application

In this study, we applied iron (-oxide) incorporated carbide nanofiber composites as heterogeneous catalysts with wide visible-light absorption ability, catalytic reactivity, and catalytic stability for the highly efficient decomposition performance. Notably, water vapor activated iron (-oxide) inco...
