“…The final concentrations of TCH and MG were determined by UV spectrophotometer (UV-2450, Shimadzu, Japan) at 357.0 nm and 617.0 nm respectively. Adsorption amounts of TCH and MG were calculated according to Equations (1) and (2).…”

“…Especially, various waste water containing antibiotic and dyes have been emitted from pharmaceutical factory and textile dyeing [1]. Tetracycline hydrochloride (TCH), as a kind of antibiotics, has been used for the treatment and prevention of diseases for human and animals [2]. However, most of TCH ingested by animals is excreted from the body through urine, and then enters rivers and oceans through ecological circulation, which in turn leads to creation of drug-resistant bacteria and pollution for the environment, therefore affects ecosystems  Corresponding Author.…”

As a kind of waste water produced by papermaking industry, bamboo pulp black liquor (BPBL) discharged into water cause serious environmental problems. In this work, BPBL was successfully converted into porous carbon after activation with KOH through one-step carbonization, and adsorption properties of porous carbon derived from bamboo pulp black liquor (BLPC) for tetracycline hydrochloride (TCH) and malachite green (MG) were studied. Adsorption capacity of BLPC for TCH and MG arrive at 1047 mg/g and 1277 mg/g due to its large specific surface area of 1859.08 m2/g, respectively. Kinetics and isotherm data are well fitted to the pseudo-second-order rate model and Langmuir model, respectively. Adsorption experiments and characterizations reveal that the adsorption mechanism involves in TCH and MG adsorption on BLPC mainly depends on the synergistic effect of pore filling, H-bonding, π-π interactions and weak electrostatic interactions. In addition, BLPC shows excellent photo-thermal property and improves its adsorption properties for TCH and MG under near-infrared irradiation. The synthesized BLPC with high adsorption efficiency, good recovery ability, improved adsorption under near-infrared irradiation can be promising and effective adsorbents for TCH or MG or other pollutes.

“…Due to its enthralling electrical and optical properties, it is being used in various applications such as gas sensing, LED, smart windows, supercapacitors, batteries, energy storage, DSSCs, optical switch coatings and photocatalysis ( Al-Muntaser et al, 2022 ; Noby et al, 2022 ; Selvakumar and Palanivel, 2022 ). However, its wide application in photocatalytic removal of organic toxins is limited due to its large band gap (∼3.1 eV), smaller visible-light absorption cross-section and lower photo-excitons separation ( Zheng et al, 2021 ).…”

Water pollution caused by the frequent utilization of pesticides in the agriculture industry is one of the major environmental concerns that require proper attention. In this context, the photocatalytic removal of pesticides from contaminated water in the presence of metallic oxide photocatalysts is quite in approach. In the present study, Orthorhombic MoO3 has been modified with varying amount of cobalt oxide through wet impregnation for the removal of imidacloprid and imidacloprid-containing commercially available insecticide. The solid-state absorption response and band gap evaluation of synthesized composites revealed a significant extension of absorption cross-section and absorption edge in the visible region of the light spectrum than pristine MoO3. The indirect band gap energy varied from ∼2.88 eV (MoO3) to ∼2.15 eV (10% Co3O4-MoO3). The role of Co3O4 in minimizing the photo-excitons’ recombination in MoO3 was studied using photoluminescence spectroscopy. The orthorhombic shape of MoO3 was confirmed through X-ray diffraction analysis and scanning electron microscopy. Moreover, the presence of distinct absorption edges and diffraction peaks corresponding to Co3O4 and MoO3 in absorption spectra and XRD patterns, respectively verified the composite nature of 10% Co3O4-MoO3. The photocatalytic study under natural sunlight irradiation showed higher photocatalytic removal (∼98%) of imidacloprid with relatively higher rate by 10% Co3O4-MoO3 composite among all contestants. Furthermore, the photocatalytic removal (∼93%) of commercially applied insecticide, i.e., Greeda was also explored.

“…9 Among these strategies, photocatalysis has been proved to be the most environmentally friendly, sustainable and effective way to degrade organic pollutants under light irradiation. 10,11 In addition, semiconductors have drawn attention as effective photocatalysts. 12 However, photocatalysis also faces different challenges, such as low photocatalytic activity and a high electron hole recombination rate.…”
