Purification of water using TiO2/g-C3N5 nanocomposite: A visible light assisted photocatalytic activity

引用

Zeitschrift fur Physikalische Chemie 2024年第10期238卷 1931-1941页

Tetracycline hydrochloride (TCN), widely recognized for its broad-spectrum efficacy and cost-effectiveness as an antibiotic, has raised significant environmental and health concerns due to its contamination in water bodies. This study introduces an innovative approach to address this issue by employing a titanium dioxide/graphitic carbon nitride (TiO2/g-C3N5) nanocomposite through photocatalysis. The synthesis of this composite involved a hydrothermal method, and a comprehensive characterization was conducted using XRD, FT-IR, and SEM techniques. The formed heterojunction between TiO2 and g-C3N5 exhibited remarkable photocatalytic degradation capabilities, achieving a removal rate of over 85% within a short period of 135min. This signifies the composite's efficiency in breaking down TCN in aqueous environments. Beyond its high effectiveness, the TiO2/g-C3N5 nanocomposite presents itself as an environmentally friendly and sustainable solution for addressing the critical issues associated with antibiotic contamination in water. This study underscores the potential of photocatalysis using TiO2/g-C3N5 as a promising technology for mitigating the adverse effects of TCN on both ecosystems and human health. © 2024 Walter de Gruyter GmbH, Berlin/Boston.

Facile synthesis of MIL-100(Fe) adsorbents for boosting organic dye removal

Highly effective MIL-100(Fe) adsorbent material was successfully synthesized from (NH4)2Fe(SO4)2·6H2O and H3BTC precursors under mild conditions. Characteristics regarding crystal structure, functional groups, elemental composition, surface morphology, specific surface area, and surface charges revealed the formation of pure and microporous MIL-100(Fe) adsorbent with a super surface area (1916.26 m2/g). The results showed that the adsorption of tartrazine organic dye was affected by adsorption time, solution pH, adsorbent dosage, pollutant concentration, and temperature. The adsorption kinetics was best described by a pseudo-second-order model with a coefficient of determination R2 = 0.999. The Toth and Langmuir models best fitted to the experimental data, showing a maximum adsorption uptake of 104.913 mg/g, which is much better than many other adsorbents. The thermodynamic parameters revealed the adsorption process of tartrazine on MIL-100(Fe) material was exothermic, spontaneous, and mainly controlled by chemical adsorption. The desorption and reuse ability of the material was effectively performed by using ethanol (98%), which showed an adsorption efficiency still remained at 88% after five adsorption cycles. This work provides an environmentally friendly synthesis of MIL-100(Fe) material with high adsorption efficiency and opens up opportunities to develop new materials for organic dye treatment in water. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

This paper proposes a non-isolated modified Quadratic DC-DC Boost Converter (mQBC) in a stacked configuration with reduced switch voltage stress while drawing continuous input current. Conventional Quadratic DC-DC Boost Converter (QBC) consists of an active switch, three diodes, two inductors, and two capacitors. However, the voltages across the active switch and the output capacitor are same as the output voltage. The proposed mQBC topology is primarily based on the conventional quadratic boost converter while replacing one of the three diodes with an active switch. Different modes of operation have been explained, and steady-state analysis of the mQBC in continuous conduction mode (CCM) has been done, incorporating the voltage stress across the components and non-ideal voltage gain. A comparative analysis with existing literature is also presented. A dual-loop control strategy is employed to regulate the output voltage of mQBC irrespective of dynamic load variations and changes in input voltage. MATlab simulation results have been provided to validate the operation and performance of mQBC.

A transformerless Quadratic DC-DC Boost converter based on a Switched-Capacitor Structure (QBSCS) has been proposed in this paper. Due to the non-ideality of components, the duty ratio limitation of a conventional Quadratic DC-DC Boost converter (QBC) restraints the voltage gain. The QBSCS enhances the voltage conversion ratio while maintaining continuous input current and a common ground shared between the input and output. The switch configuration in the proposed QBSCS reduces the voltage stress across the switches while maintaining high voltage gain. A comprehensive mathematical analysis is presented for each mode of operation, assuming that the proposed QBSCS operates in Continuous Conduction Mode (CCM). The proposed converter has been compared with the existing converters based on the nature of input current, conversion ratio, switch voltage stress, and total component count. The QBSCS converter is simulated in MATlab Simulink in closed-loop control and verified under various operating conditions, and corresponding simulation results are shown to validate its performance.
