BiOCl/(BiO)2CO3 composites with reactive exposed {001} facets have been synthesized by a one-step in situ solvothermal method. The synergistic effect of type-II band alignment and exposed high-energy facets enhances photocatalytic activity.
NIR-light emitting CDs (R-CDs) were prepared using spinach as a precursor by one-step solvothermal treatment. The R-CDs exhibited great optical properties, negligible toxicity, and superior labelling capability both in vitro and in vivo.
