“…[17][18][19] For solving these problems, morphological regulation is an effective method. In addition, various morphologies of g-C 3 N 4 have been synthesized by many researchers, such as nanorods, [20] nano-sheets, [21] nanotubes, [22] and so forth. For example, Wang et al [22] constructed 1D mesoporous tubular g-C 3 N 4 catalysts using halloysite nanotubes (HNTs) as a hard template, which exhibited a large specific surface area (SSA) and accelerated the separation of charge carriers.…”

Among the traditional treatment processes for purifying wastewater contaminated with Rhodamine B (RhB), semiconductor photocatalysis is the most effective technology because it can oxidize organic pollutants and convert them into CO2, H2O, and other harmless molecules in a safe and efficient manner. According to literature research, it is feasible to enhance the performance of g‐C3 N4 as a photocatalyst by constructing a heterojunction with other photocatalytic materials. Morphological regulation of carbon nitride (g‐C3N4) is a viable strategy for improving its photocatalytic activities. By controlling the morphology of g‐C3N4, factors such as light absorption, specific surface area, charge separation, and reaction sites can be optimized to enhance its photocatalytic efficiency. Three‐dimensional tremella‐like carbon nitride (3DT‐CN) and 3D‐CN/TiO2/HNTs (halloysite nanotubes) were prepared using bubble templates and an impregnation method respectively. The Z‐scheme heterojunction structure constructed by 3D‐CN and TiO2 promotes electron‐hole separation. Catalytic experiments demonstrated that under irradiation for 120 min, the 3D‐CN/TiO2/HNTs catalyst could eliminate 86.48 % of Rhodamine B (RhB). Additionally, active radicals such as e‐, h+, ⋅OH, and ⋅O2‐ are involved in RhB degradation. Therefore, the three‐dimensional tremella‐like 3D‐CN/TiO2/HNTs heterojunction photocatalyst has great potential for environmental purification.

Photocatalytic technology, as an environmentally friendly technology, has a great application promise in the treatment of environmental pollutants caused by residual pharmaceuticals emissions. The Z‐scheme heterojunction of g‐C3N4/g‐C3N4/Pr6O11 (Pr/CN) was successfully prepared by employing melamine, urea, and praseodymium nitrate as co‐precursors. The structure composition and photoelectrochemical properties were characterized by XRD, XPS, EDS, SEM, FETEM, UV–Vis, EIS, photocurrent, and PL analyses. The optimized 5wt%Pr/CN heterojunction degrade 98% of SCP, 85% of SMM, and 87% of SDM, respectively. Taking SCP as an example, the degradation rate is 8 and 11.2 times higher than that of the g‐C3N4/g‐C3N4 homojunction and g‐C3N4, respectively. The remarkable photocatalytic efficiency of Pr/CN heterojunction could be ascribed to enhanced visible light absorption and enhanced migration and separation of photogenerated charge carriers. Furthermore, the degradation products and degradation pathways of SCP and SMM were established by HPLC‐MS/MS analysis. In addition, the toxicity of the intermediate was evaluated with quantitative structure–activity relationship (QSAR) prediction and the biocompatibility of sulfonamide‐degrading solution over the Pr/CN photocatalyst was verified by the growth of wheat seeds.
