AI Article Synopsis
- This study examines how effectively clofibric acid, a pharmaceutical drug, breaks down using TiO-coated glass rings in a fixed-bed reactor when exposed to UV light.
- A new kinetic model was created to explain this degradation process, focusing on how well the surface absorbs UV radiation through a concept known as local surface rate of photon absorption (LSRPA).
- The Monte Carlo method was used to analyze how photons interact with the coated rings, and the model's predictions closely matched experimental results from tests with varying catalyst coatings and radiation levels.
Article Abstract
This work presents the photocatalytic degradation of the pharmaceutical drug clofibric acid in a fixed-bed reactor filled with TiO-coated glass rings. Experiments were carried out under UV radiation. A kinetic model that takes into account radiation absorption by means of the local surface rate of photon absorption (LSRPA) has been developed. The LSRPA was obtained from the results of a radiation model. The Monte Carlo method was employed to solve the radiation model, where the interaction between photons and TiO-coated rings was considered. Data from experiments carried out with rings with different numbers of catalyst coatings and different irradiation levels were used to estimate the parameters of the kinetic model. A satisfactory agreement was obtained between model simulations and experimental results.

This study presents a facile one-pot synthesis method to fabricate BiFeO-BiFeO-BiO heterojunction photocatalysts with controllable compositions and pure phases. Three different binary heterojunctions (BiFeO/BiFeO, BiFeO/BiO, and BiFeO/BiO) and a ternary BiFeO/BiFeO/BiO heterojunction were formed, all exhibiting significantly enhanced photocatalytic performance for the degradation of methylene blue (MB) and phenol under visible light irradiation, outperforming the individual compositions. Notably, the BiFeO/BiFeO heterojunction achieved the highest degradation efficiency (93.

The development of efficient and sustainable photocatalysts for wastewater treatment remains a critical challenge in environmental remediation. In this study, a ternary photocatalyst, Cu-CuO/g-CN, was synthesized by embedding copper-copper oxide heterostructural nanocrystals onto g-CN nanosheets via a simple deposition method. Structural and optical characterization confirmed the successful formation of the heterostructure, which combines the narrow bandgap of CuO, the high stability of g-CN, and the surface plasmon resonance (SPR) effect of Cu nanoparticles.

One-dimensional (1D) hierarchical photocatalyst has the advantages of 1D materials and hierarchical materials, which is a kind of potential high performance photocatalytic materials. However, how to efficiently synthesize 1D hierarchical BiOBr is still a huge challenge. Herein, 1D rod-like BiO(OH)(NO)·3HO, the hydrolysis product of Bi(NO)·5HO, was acted as both the template and Bi source to synthesize 1D hierarchical hollow BiOBr (1DHHBr) through a facile solution stirring method at room temperature, using KBr as Br source.
