“…g-C 3 N 4 , a representative nonmetallic semiconductor, has a highly delocalized π-conjugated system formed by the hybridization of CN atoms with sp 2 [ 27 ]. Despite its recent emergence in the public eye, g-C 3 N 4 has gained attention due to its excellent chemical and thermal stability, affordability, availability, and environmental characteristics [ 28 , 29 , 30 ]. It has been identified as one of the most promising photocatalysts in the realm of wastewater treatment [ 31 ].…”

Using an ultrasound-assisted chemical technique, ZnO quantum dot and ZnO composites were created. The optical characteristics and structural details of these composites were examined using TEM, XRD, XPS, FT-IR, UV-vis, and BET. The results revealed that both the ZnO quantum dot composite and ZnO composite exhibited outstanding optical properties, making them suitable for photocatalytic reactions. In order to analyze the photocatalytic performance, a degradation experiment was conducted using Rhodamine B solution as the simulation dye wastewater. The experiment demonstrated that the degradation of Rhodamine B followed the first-order reaction kinetics equation when combined with the photocatalytic reaction kinetics. Moreover, through cyclic stability testing, it was determined that the ZnO QDs-GO-g-C3N4 composite sample showed good stability and could be reused. The degradation rates of Rhodamine B solution using ZnO-GO-g-C3N4 and ZnO QDs-GO-g-C3N4 reached 95.25% and 97.16%, respectively. Furthermore, free-radical-trapping experiments confirmed that ·O2− was the main active species in the catalytic system and its photocatalytic mechanism was elucidated. The photocatalytic oxidation of ZnO quantum dots in this study has important reference value and provides a new idea for the subsequent research.

The development of low‐cost and high‐efficiency oxygen evolution reaction (OER) photoelectrocatalysts is a key requirement for H2 generation via solar‐assisted water splitting. In this study, we report on an amenable fabrication route to carbon cloth‐supported graphitic carbon nitride (gCN) nanoarchitectures, featuring a modular dispersion of NiO as co‐catalyst. The synergistic interaction between gCN and NiO, along with the tailoring of their size and spatial distribution, yield very attractive OER performances and durability in freshwater splitting, of great significance for practical end‐uses. The potential of gCN electrocatalysts containing ultra‐dispersed, i. e. “quasi‐atomic” NiO, exhibiting a higher activity than the ones containing nickel oxide nanoaggregates, is further highlighted by their activity even in real seawater. This work suggests that efficient OER catalysts can be designed through the construction of optimized interfaces between transition metal oxides and carbon nitride, yielding inexpensive and promising noble metal‐free systems for real‐world applications.
