“…BC has been known for its application on wastewater treatment, soil and sediment adsorption. Furthermore, BC has recently used as supporting materials [21], [22]. In other hands, BC were reported used as an adsorbent to remove heavy metals [9], [23] and organic waste [20], [24], [25].…”

In this work, CuAl/Biochar (BC) composite was prepared by the coprecipitation method. The materials were applied to remove malachite green in aqueous solution. These materials were characterized using XRD, FTIR, BET and SEM-EDX analyses. The composite material was confirmed by X-ray diffractograms with reflection (002) at 24o and the appearance of new peaks at 1095 cm -1 . The BET result of CuAl/BC composite has larger surface area is 168 m 2 /g than 46 m 2 /g for LDH. The morphologies of composite materials show agglomeration and micro particle size. The result of the adsorption study indicated the composite material follows pseudo-second-order (PSO) and Langmuir isotherm models. The maximum adsorption capacity of malachite green using CuAl/BC uptake is 164.316 mg/g. The thermodynamic analysis indicates that the malachite green adsorption is spontaneous, endothermic. Regeneration study of adsorbent CuAl/BC composite shows after four times reused, it still has high removal efficiency at 89%.

Biochar (BC) is a carbon-rich material produced from pyrolysis of biomass. In addition to its low toxicity, environmental compatibility, and low cost, BC has the desired advantages of well-developed mesoporous structure and abundant surface functional groups. In recent years, BC-based photocatalysts (BCPs) have played a significant role in many environmental fields. In this paper, we highlight the current progress and several exciting results of BCPs by focusing on their synthesis, characterization, mechanisms, and applications in wastewater treatment. Details on various preparation methods include sol–gel, hydrothermal/solvothermal, ultrasound, calcination, and in situ methods are summarized and discussed. The underlying mechanisms and the applications of BCPs for different semiconductors are reviewed. Furthermore, some future trends and potentials are outlined.

“…Antibiotics are mainly used in health care, animal husbandry, and aquaculture, especially now the extensive use of Pharmaceuticals and Personal Care Products (PPCPs), the pollution of water resources caused by excess antibiotics has attracted much attention. At present, the widely used antibiotics mainly include quinolones [ 225 ] (QNs), fluoroquinolones [ 226 ] (FQs), and tetracyclines [ 227 ] (TCs), and so on, among which TCs is one of the most frequently detected antibiotics in sewage. However, antibiotic wastewater has the characteristics of low concentration, high antibacterial activity, and inhibition to microorganisms, conventional biochemical and physicochemical water treatment processes are not ideal methods for the removal of antibiotics, while TiO 2 has a good application prospect in the treatment of antibiotic wastewater.…”

Titanium dioxide (TiO2) has the advantages of strong photocatalytic activity, non‐toxicity, and low cost, and so on. It has always occupied a dominant position in many photocatalytic materials, especially nanoscale spherical TiO2 has the characteristics of high specific surface area and pore‐volume, and so on. Therefore, Degussa P25, as a typical representative of the nanoscale spherical structure, is currently the only material produced on a large scale. According to the structure, nanoscale spherical TiO2 can be divided into three types: solid, core‐shell, and hollow spheres. However, there is still a lack of the latest review on the synthetic doping and application of nanoscale spherical TiO2. Therefore, we first describe the degradation mechanism of nanoscale spherical TiO2 and summarize the latest progress of its synthesis strategy in this review, including doping and other modification techniques, and finally introduce the application of nanoscale spherical TiO2 photocatalytic degradation of volatile organic compounds, dye wastewater, antibiotics, pesticides, and oily wastewater. Through this review, it is helpful for researchers to further understand the synthesis and application of nanoscale spherical TiO2, hoping to continuously improve the disadvantages and photocatalytic activity of nanoscale spherical TiO2, and promote the widespread application of nanoscale spherical TiO2 on an industrial scale.
