The development of green, efficient, and reusable photocatalysts is important for pollution degradation. In recent years, Cs3Bi2I9 has been shown to be an effective photocatalyst. However, the rapid recombination electrons holes weakens photocatalytic activity. this work, photogenerated electron transfer rate was promoted by ZIF-8 compositing with Cs3Bi2I9, which effectively improved pollutant After 50 min visible light irradiation, Cs3Bi2I9/ZIF-8 removed up 98.2% methylene blue (MB), 4.15 times higher than that alone. addition, composite still exhibited high activity after three cycling experiments. Our research offers a simple efficient method enhancing lead-free halide perovskites.

Abstract Developing efficient visible light photocatalytic materials has always been a challenge for researchers. We have successfully prepared series of corn straw based carbon doped Nb2O5 with excellent performance under light. A characterizations were carried out on the synthesized materials, including power X-Ray diffraction(XRD), scan electron miscopy (SEM), nitrogen adsorption, infrared spectroscopy(IR), UV-vis diffuse reflectance spectra, X-ray photoelectron spectroscopy(XPS). The samples was investigated irradiation using Rhodamine B as degradation target. experimental results show that introduction element certain impact morphology, specific surface area, pore size distribution, elemental composition, functional groups, and absorption sample, which in turn significant its performance.This article is great significance application biomass improvement environmental quality, also provides new ideas design synthesis composite materials.

In this study, it was aimed to remove Oxytetracycline (Oxy), one of the pharmaceutical wastes, with powder pine tree (Pinus nigra Arn.) needle waste (Pn-nw). Experimental data obtained from batch adsorption studies carried out at pH 5.0 ±0.5 and temperature 23±2oC were tested Pseudo first order, second order Intraparticle diffusion kinetic models Freundlich, Langmuir Temkin isotherm also error functions (Error Sum Squares (SSE), Absolute Errors (SAE) Average relative errors (ARE)). Furthermore, support Oxy onto Pn-nw's, characterization both raw charged particles done by Fourier transform infrared spectroscopy (FTIR) scanning electron microscope (SEM) analyses. The most appropriate model in study determined be an R2 value 0.999 Freundlich 0.991. Additionally, amount removed per unit Pn-nw (qmax) calculated as 30.35 mgOxy/gPn-nw. results show that is a very promising environmentally friendly adsorbent for removal.
