Metal-free photocatalysts have attracted growing concern in recent years. In this work, a new class of carbon quantum dots (CQDs) modified porous graphitic carbon nitride (g-C3N4) is synthesized via a facile polymerization method. With the optimal CQDs loading, the CQDs modified g-C3N4 exhibits ∼15 ...

A novel tubular graphitic carbon nitride (g-C3N4) modified with carbon quantum dots (CQDs) was fabricated and employed for the elimination of carbamazepine (CBZ) under visible light irradiation. The as-fabricated metal-free catalysts exhibited tubular morphologies due to the preforming of tubular pr...

The geochemical behavior of hexavalent chromium (Cr(VI)) in cold environments is profoundly influenced by freezing processes. This study reveals a fundamental switching of dissolved organic matter (DOM)-mediated Cr(VI) reduction mechanisms between aqueous and ice phases. In the aqueous phase, the re...
