Traditional Type-I heterojunctions, the combination of large- and narrow-bandgap semiconductors, possess a long electron transmission path an electron–hole confinement region, making them not conducive to improving catalytic performance. Hence, few studies about heterostructure combined with large narrow bandgap in chemocatalysis were invested, especially terms reaction mechanism. Herein, (CdS) (hexagonal boron nitride, h-BN) selected as research objects fabricate h-BN/CdS heterojunction by Joule heating ultrafast procedure. Density functional theory (DFT) calculations performed showed that heterojunctions photogenerated electrons (e–) transferred from h-BN CdS, while holes (h+) moved conversely, which is completely different classical heterojunctions. Thus, nonclassical was successfully constructed, proved DFT experimental verification, revealed excellent visible light response photocatalytic degradation ability tetracycline (TC). The optimized exhibited high rate 84.78% under irradiation. Additionally, applicability expanded photodegradation water environments. A materials proposed, opened up new for efficient photocatalysis antibiotic wastewater degradation.

The HKUST-1 metal-organic framework was synthesized using four different copper(II) salt precursors, namely copper nitrate, sulphate, acetate, and chloride, via the solvothermal method with no mixing. Syntheses were conducted without N,N-dimethylformamide to allow for a greener synthesis of MOFs. selected physicochemical properties obtained frameworks determined. yield products changed in order acetate>nitrate>sulfate, while product chloride. materials characterized by means XRD, nitrogen adsorption–desorption at −196 °C, FTIR, XPS, TGA, SEM, DLS. morphology crystallites their significantly affected when precursors used. comparison results already published works allows correlation parameters like temperature, time, mixing, precursor used on final product.

ABSTRACT Metal–organic frameworks (MOFs) are well‐known for their promising applications in photocatalysis, but single‐component MOFs have limited effectiveness degrading organic pollutants. To address this, we designed a novel photocatalyst the efficient degradation of p‐nitrophenol (p‐NP). In this study, synthesized two‐dimensional [Co (tib)(mpda)(H 2 O) ]·H O (Co‐MOF) (tib = 1,3,5‐tris(1‐imidazolyl)benzene, H mpda 1,3‐phenylenediacetic acid) using hydrothermal method. Silver particles were then deposited on surface Co‐MOF via photo‐reduction method, forming Ag@Co‐MOF. The incorporation Ag accelerated photogenerated carrier transport and prevented recombination electrons (e − ) holes (h + ), resulting superior photocatalytic performance. bandgap energy is 3.4 eV, whereas that Ag@Co‐MOF reduced to 2.8 significantly enhancing visible light absorption. After 240 min illumination, achieved efficiency 92.7% p‐NP, with rate 0.0095 −1 . Analysis active substances intermediates through free radical trapping tests, ESR XPS valence band LC–MS revealed promoted generation ·OH ·O , facilitating rapid oxidative p‐NP. summary, provides sustainable green pathway pollutant removal environmental remediation, while also expanding application areas MOF materials.
