Core-shell spherical cerium oxide, N-doped carbon dots and copper oxide nanocomposites with oxidase-like activity for colorimetric detection of hexavalent chromiums

Synthesis of N-GQDs/CuS/Cv-CNNs hydrogels and their performance in hexavalent chromium wastewater treatment

“…Hexavalent chromium (Cr( vi )) pollution, commonly found in the petroleum refining, metal smelting, electroplating and tanning industries, may infiltrate into water sources and soils through wastewater discharges and waste accumulation, jeopardizing ecosystems, and soil health. 1,2 Research on effective treatment technologies for hexavalent chromium in the environment is essential.…”
