The TiO2-Fe3O4-bentonite was used in this study as a photocatalyst material for antimicrobial. The material was coated on a ceramic container. This study is the preliminary study on coatings formulated using TiO2-Fe3O4-bentonite to fight against microbial. This paper aims to emphasize the application of TiO2-Fe3O4-bentonite in the water purification process by adding material into the paint and coating it on ceramic containers as a reactor to help neutralize E. coli and S. Aureus. The TiO2-Fe3O4-bentonite powder was synthesized by the sol-gel method. The photocatalyst powder was exhaled on the surface of the inside painted-walls of the reactor. Some photo-catalytic parameters have been investigated, such as the photocatalyst concentrations and the initial concentration of E. coli starter, and S. Aureus starter. The result showed that the higher the concentration of the photocatalyst material, the more effective its degradation. Also, the highest death rate occurs when the initial concentration of the E. coli starter is at 107 CFU/ml. Photo-degradation in gram-negative bacteria (E. Coli) gives more promising results than the process in gram-positive bacteria (S. aureus). The characterization of the material showed that the photocatalyst material leached during the photo-degradation process. This causes the more extended the reaction takes place; there will be a decrease in bacterial photo-degradation activity. Also, the use of solar light in the photo-catalysis process is more effective than UV light.

As the core of polymer chemistry, manufacture of functional polymers is one of research hotspots over the past several decades. Various polymers are developed for diverse applications due to their tunable structures and unique properties. However, traditional step‐by‐step preparation strategies inevitably involve some problems, such as separation, purification, and time‐consuming. The multicomponent reactions (MCRs) are emerging as environmentally benign synthetic strategies to construct multifunctional polymers or composites with pendant groups and designed structures because of their features, such as efficient, fast, green, and atom economy. This mini review summarizes the latest advances about fabrication of multifunctional fluorescent polymers or adsorptive polymeric composites through different MCRs, including Kabachnik–Fields reaction, Biginelli reaction, mercaptoacetic acid locking imine reaction, Debus–Radziszewski reaction, and Mannich reaction. The potential applications of these polymeric composites in biomedical and environmental remediation are also highlighted. It is expected that this mini‐review will promote the development preparation and applications of functional polymers through MCRs.
