Summary: A new type of composite material, biopolymer-silica materials, is proposed as selective and effective adsorbents. A new synthesis procedure using geometrical modification of silica and mechanosorption of chitosan is applied to create chitosan-nanosilica composites (ChNS) and chitosan-silica gel composites (ChSG). The adsorption efficiency of ChNS and ChSG towards anionic dyes was analyzed and the results showed that ChNS had faster adsorption kinetics due to the silica-type effect.

Summary: In this study, a novel Yb metal-organic frameworks (Yb-MOF) was synthesized and modified for the removal of Cu(II) and As(V) from simulated wastewater. The adsorption processes of Cu(II) and As(V) were found to follow Freundlich, Langmuir, and Temkin models, with high adsorption capacities. The kinetics and thermodynamics of the adsorption process were also investigated, revealing that chemisorption played a dominant role. The adsorption of Cu(II) and As(V) by modified Yb-MOF was found to be spontaneous at certain temperatures.

Summary: Green synthesis of zinc(II) metal-organic framework (Zn-MOF) was achieved using spent domestic batteries as a source of Zn metal and benzene dicarboxylic acid as a linker. The synthesized Zn-MOF exhibited similar properties to those reported in literature and remained stable in water. The adsorption of three dyes onto the Zn-MOF followed a pseudo-second-order kinetic model and Freundlich isotherm model. Thermodynamic analysis revealed that the adsorption of one dye was endothermic and spontaneous, while the uptake of the other two dyes was non-spontaneous and exothermic. This study contributes to the development of value-added MOFs from solid waste.

Summary: Biosorption using a chitosan-pectinase blend (CPB) was studied for the removal of methylene blue (MB) dye from synthetic solutions. The blend showed a rough surface morphology and amorphous nature. Fourier-transform infrared (FTIR) analysis confirmed the successful blend formation. Maximum adsorption was achieved at pH 7.0, 30°C, 30 min contact time, and an adsorbent dosage of 2.5 g/L. The pseudo-second-order model provided the best fit, with the highest R2 value close to 1. The Temkin isotherm model showed the highest adsorption capacity at 16.81 mg/g. The blend demonstrated good desorption ability, allowing for reuse in dye removal.

Summary: Biomass layered hybrids were synthesized by in situ growth from rice husk and microwave-assisted synthesized MIL-53(Al) particles, leading to reduced reaction times. The resulting hybrid (MIL-53(Al)@RH) showed high crystallinity, thermal decomposition phases, and functional groups. The hybrid particles exhibited easy separation during heterogeneous processing and maintained the properties of MIL-53(Al) for the removal of Oxytetracycline, Diclofenac, and Glyphosate in aqueous solutions.

Summary: In this study, porous chitosan/UiO-66 composite foams were prepared by grafting UiO-66 into polymerized chitosan. The foams exhibited low density and superior liquid-solid separation performance. The adsorption of ketoprofen by the composite foams was attributed to hierarchical pores and abundant functional groups. The adsorption mechanism was determined to be hydrogen bonding and 7C-7C interaction according to density functional theory calculations.

Summary: Fibrous silica tantalum (FSTa) and metal oxides (AgO, CuO, ZnO)/FSTa catalysts were prepared and characterized for the photocatalytic oxidative desulfurization (PODS) of dibenzothiophene (DBT). The addition of metal oxides decreased the efficiency of PODS, possibly due to mismatched redox potentials. Among the metal oxides loaded FSTa, Zn/FSTa exhibited higher desulfurization rate and could directly oxidize DBT into dibenzothiophene sulfone (DBTO2). The kinetics study showed that the photodegradation over Zn/FSTa followed the pseudo-first-order and adsorption was the rate-limiting step.

Summary: In this study, aluminosilicate and ZSM-5 catalysts were synthesized from low-grade Indonesian kaolin. High quartz impurities in the kaolin were successfully reduced by washing, centrifugation, and Fe3+ treatment. All catalysts showed mesoporous structure and pore diameter of around 3.5 nm. The catalytic activity of the aluminosilicate catalyst was higher than that of ZSM-5, and the addition of Fe3+ enhanced the catalytic activity of the aluminosilicate. However, Fe3+ addition to ZSM-5 showed only a slight increase in conversion.

Summary: Tricobalt tetroxide (Co3O4) has shown promising potential as a photocatalyst material, but its photocatalytic performance is hindered by the rapid recombination process of photogenerated charge carriers. Various modifications, such as doping elements, support materials, and combination with other semiconductors, have been developed to enhance its photocatalytic activity by decreasing the recombination process and improving charge carrier separation. This work reviews recent modifications of Co3O4 and their effects on its photocatalytic performance, as well as the mechanisms behind these modifications.

Summary: Cellulose nanofibers (CNs) are obtained from cotton wool using subcritical water in a semiflow hydrothermal reactor, resulting in green hydrolysis. The yield and crystallinity index (CI) of nanocellulose are optimized by varying temperatures and hydrolysis time at a pressure of 10 MPa. Increasing temperatures enhance hydrolysis rates, leading to smaller nanofibrils. At 180°C, amorphous cellulose dissolves, increasing crystallinity without disrupting the fibrous network. In the presence of H3O+ at 230°C, cotton wool is hydrolyzed into uniform nanofibril cellulose with a diameter of 14.3±1.2 nm. Cellulose nanofibers obtained at 220 and 230°C improve tensile strength and elongation at break due to their small sizes and efficient dispersion in the poly(vinyl alcohol) (PVA) matrix.

Summary: The problem of industrial dye wastewater is a critical environmental challenge that requires urgent attention. This study proposed immobilization of a mixed Trichoderma viride and Ralstonia pickettii culture into a Sodium alginate-Polyvinyl Alcohol-Bentonite (SA-PVA-Bentonite) matrix for the decolorization and degradation of Methylene Blue (MB). The results showed that the immobilized culture outperformed the free cells, achieving an impressive 97.88% decolorization rate. LCMS analysis revealed the production of three metabolite product degradations, and SEM-EDX analysis confirmed the agglomeration of the culture within the SA-PVA-Bentonite matrix. This study presents a potential solution to environmental problems associated with industrial dye wastewater.

Summary: Optimizing the hierarchical ZSM-5 structure by varying the first hydrothermal step at different times provides insight into the evolution of micro/mesopores and their effect as a catalyst for deoxygenation reaction. Monitoring the incorporation of tetrapropylammonium hydroxide (TPAOH) and N-cetyl-N,N,N-trimethylammonium bromide (CTAB) helps understand their role in pore formation. The optimized hierarchical ZSM-5, achieved through hydrothermal condensation at 3 hours, exhibits high acidity and micro/mesoporous synergy, resulting in 71.6% diesel hydrocarbon selectivity due to improved diffusion within the hierarchical structures.
