In the present work, degradation of p-nitrophenol (PNP) and its mineralization by a UV/Vis-based persulphate activation process was investigated. Firstly, screening processes as direct photolysis, alone activated radiation performed. The incidence demonstrated to have an important role in oxidant activation, allowing achieve highest PNP total organic carbon (TOC) removals. maximum oxidation (10...

NIR light induced H2 evolution was realized by metal-free photocatalysis for the first time. The considerable H2 production at 808 nm and large promotion of the photocatalytic activity in both UV-Vis and Vis regions originated from the synergistic effect on spectral and electronic coupling of g-C3N4 nanosheets and carbon quantum dots.

The physicochemical characterization of nanomaterials (NMs) is often an analytical challenge, due to their small size (at least one dimension in the nanoscale, i.e. 1–100 nm), dynamic nature, and diverse properties. At same time, reliable repeatable paramount ensure safety quality manufacturing NM-bearing products. There are several methods available monitor achieve measurement nanoscale-relate...
