Abstract Three triazine‐based conjugated porous polymers (CPPs) are synthesized via a Pd‐catalyzed Suzuki‐Miyaura coupling reaction between derivatives of 2,4,6‐tri(thiophen‐2‐yl)‐1,3,5‐triazine (TTT) and 2,4,6‐triphenyl‐1,3,5‐triazine (TPT). Photocatalysis experiments demonstrate that the hydrogen evolution rate (HER) ThTh‐CPP (homopolymer TTT) reach an exceptional 46.4 mmol g⁻¹ h⁻¹ without co‐catalysts, surpassing ThPh‐CPP (8.26 h⁻¹, copolymer TTT TPT) PhPh‐CPP (3.06 homopolymer TPT), as well nearly all similar polymer‐based catalysts reported to date, under visible light. The variance in photocatalytic activity is attributed differences linkage units on triazine ring. Mechanistic analysis, combining experimental theoretical studies, highlights potential engineering electron‐donating ability enhance polymers.

The correlation between structure and properties in the photodegradation reaction of bismuth oxychloride (BiOCl) was explored this work. Three BiOCl samples with different sizes, morphological structures, defects were prepared through a hydrothermal method experimental manipulation. Their structural comprehensively characterized using X-ray diffraction, scanning electron microscopy, transmission spin resonance, photoelectron spectroscopy, Fourier transform infrared ultraviolet–visible diffuse reflectance photoluminescence. Taking tetracycline hydrochloride (TC-HCl) as probe reaction, we found that high activity could be achieved by decreasing their crystal size thickness, introducing proper structure, assembling nanosheets to get microball structure. Combined radical-scavenge experiments resonance (ESR) spin-trap spectra, conclude ̇O2– dominant reactive oxygen species for degradation reaction. detailed pathway TC-HCl further analyzed liquid chromatography–mass spectrometry.
