“…At a lower pH, the interaction between tetracycline and the CCNP hydrogel is found to be weaker and leads to poor tetracycline degradation efficiency. But for a pH > 8, the oxidation potential of the hydroxyl radicals is noted to be low, and the self-decomposition of hydrogen peroxide into oxygen and water affects the degradation efficiency of CCNP hydrogels. , …”

“…But for a pH > 8, the oxidation potential of the hydroxyl radicals is noted to be low, and the self-decomposition of hydrogen peroxide into oxygen and water affects the degradation efficiency of CCNP hydrogels. 49,50 The effect of reaction temperature on the percarbonateassisted tetracycline degradation is emphasized in Figure S6. The experimental studies indicated a faster tetracycline degradation with an increase in temperature from 30 to 40 °C upon the inclusion of sodium percarbonate.…”

A hybrid Na, B, and O codoped g-C 3 N 4 /polypyrrole carbon black (CCNP) hydrogel is prepared via an in situ cross-linking method for percarbonate activation under visible light irradiation. The structural, morphological, and optical characterizations proved the tuned bandgap, enriched utilization of visible light, minimum recombination ratio, and higher separation efficiency. The CCNP hydrogels could easily activate the percarbonate under visible light, leading to abundant production of reactive radicals, which aids in the degradation of tetracycline in wastewater. About 96% of tetracycline was degraded in 15 min at its natural pH. The superoxide, carbonate, and hydroxyl radicals were the important radical species in tetracycline degradation. The CCNP hydrogels also exhibited high photostability and reusability up to six cycles. The tetracycline degradation pathway is given a special focus, and the percarbonate activation mechanism is highlighted. This study provides a new strategy for boosting the performance of g-C 3 N 4 -based catalysts for percarbonate activation and wastewater remediation.

A novel phosphorus‐doped graphitic carbon nitride nanosheets (PS‐CN) photocatalyst was prepared by thermal polycondensation and thermal stripping method, and its physicochemical properties were characterized. The results show that PS‐CN formed a thin sheet and multi‐cavity structure by thermal delamination that could enhance the surface area, light reception, and adsorption capacity. The prepared PS‐CN activated sodium percarbonate system (PS‐CN/SPC) was developed for the degradation of dyeing wastewater with methylene blue (MB) as the target pollutant and the degradation mechanism was analyzed. At room temperature (20 °C), the degradation rate of MB in PS‐CN/SPC system within 10 min (88.13 %) was three times that of pure g‐C3N4. In addition, the MB was completely degraded under visible light within 60 min. Moreover, PS‐CN exhibited excellent reusability that the degradation rates of MB have remained above 96 % in five consecutive cycles. The free radical quenching experiments showed that hole (h+), hydroxyl radical (•OH) and superoxide radical (•O2−) all participated in MB degradation, and •OH was the main active species. The PS‐CN/SPC system would provide a high‐value solution for the treatment of dye wastewater due to the low cost of raw materials, superior photocatalytic activity, simple synthesis method, and reusability of the catalyst.
