Introducing carbon dots to NiFe LDH via a mild coprecipitation–aging method to construct a heterojunction for effective oxygen evolution

Abstract

Modified NiFe-layered double hydroxide (NiFe LDH) materials with a high oxygen evolution reaction (OER) performance make it possible to replace noble metal catalysts for widespread applications.

In situ construction of a 2D/2D SnS2/MXene heterojunction for visible-light photocatalytic uranium reduction

“…The key factors affecting the catalytic activity of semiconductors are light absorption, separation of photoexcited e–h + , and transfer of these charge carriers. 43,44 The light absorption characteristics of prepared samples can be evaluated through UV-visible absorption spectroscopy. Fig.…”
