Summary: Geopolymers were synthesized from fly and bottom ashes of a thermoelectrical power plant in Brazil, aiming to add value to waste materials. It was found that geopolymers produced by conventional methods had higher surface area and total pore volume, while ultrasound-assisted synthesis showed better adsorption potential in some cases. Both methods demonstrated good adsorption performance for heavy metals like Ag+, Cu2+, Co2+, and Ni2+, with removal percentages exceeding 90%.

Summary: This study investigates the effect of binary composite activators on the microstructure of fly-ash-based geopolymers through 24 experiments. The results show that the Na2SiO3 & BULL;9H(2)O + KOH activator exhibits the highest mechanical strength due to the synergy activation between Na2SiO3 and K+. Furthermore, the addition of silica fume facilitates the formation of amorphous silicates and increases the pore volume. This research provides an efficient and cost-effective fabrication method for fly-ash-based geopolymer and contributes to the development of solid waste recycling techniques.

Summary: Developing innovative utilization techniques for Yellow River silt (YRS) is crucial for protecting the river. This study attempted to use YRS as a supplementary binder material in the fabrication of alkali-activated fly ash (AAFA) foam concrete. The effects of YRS dosage and alkali content on various properties of the foam concrete were examined. The results showed that incorporating YRS significantly influenced the physico-mechanical properties and structure of the foam concrete.

Summary: The mechanical properties of Agave americana fibers treated with different concentrations (1%, 5%, and 20%) and times (0.5 h, 1 h, and 3 h) of NaOH solutions were investigated. The results showed that the treatment with 1% NaOH for 1 h required the least amount of resources to improve the mechanical performance. The analysis of the fiber surface after alkaline treatment revealed that impurities were partially removed with the mildest condition (1% NaOH for 0.5 h), while surface decomposition occurred with the harshest condition (20% NaOH for 3 h). Fly ash-based geopolymer composites with different treated fiber contents were prepared and their compressive, flexural, and splitting tensile strengths were determined. The addition of fibers slightly affected the compressive strength, but improved the ductility capacity by up to 26% when 1% of treated fiber was incorporated. In terms of tensile behavior, the results indicated a direct relationship between strength and fiber content, with a 36% improvement observed with 1% fiber content. Finally, the morphology of the fiber-reinforced geopolymer matrices was studied using SEM.

Summary: Geopolymers obtained through an alternative geopolymerization process showed high efficiency in removing different metal ions. Pseudo-second-order and general order models were suitable for describing the adsorption kinetics, while Langmuir and Freundlich models were adequate for representing the adsorption equilibrium. Geopolymer derived from bottom ash (GHA) performed better in removing Cu+2, Co+2, and Ag+1, while geopolymer derived from fly ash (GFA) was more effective in Ni+2 removal. Both GHA and GFA showed high removal efficiency of over 85% in treating real effluents.

Summary: This study investigates the influence of mechanical activation and natural magnesite addition on the compressive strength of geopolymers based on natural magnesite-f ly ash blends. The mechanical activation significantly improves the geopolymer strength, while the addition of 1%-10% magnesite does not significantly affect the strength of geopolymers. The study also compares the effects of adding three Ca/Mg carbonate minerals to f ly ash and mechanical activation on geopolymer performance, with calcite showing the highest strength among the carbonate minerals.

Summary: The functionalized zinc oxide nanotube coated with MXene layer was successfully prepared using a simple dipping method. The existence of the prepared material was confirmed through various characterization techniques. The modification of ZnO NT with MXene resulted in a decrease in bandgap value and an increase in photoelectrochemical performance. The current density of ZnO NT/MXene was about 0.2 mA/cm2 (1.4 V vs Ag/AgCl), which is twice as high as that of ZnO NT. Additionally, the oxygen evolution of the modified ZnO NT was 1.5 times higher than the pristine one, indicating effective hole junction/charge transfer in ZnO NT/MXene.

Summary: Recently, there has been significant progress in the development of zeolites with two-dimensional structures, also known as nanosheet zeolites, due to their superior catalytic performance compared to conventional zeolite. The thin nanosheet structure of zeolite provides more accessible active sites, allowing for efficient catalytic reactions. Various nanosheet zeolites, including MFI, FAU, MOR, MWW, and TS-1, have been successfully synthesized using direct synthesis methods involving surfactants and/or seeds. Interestingly, the characteristics of these nanosheet zeolites can be easily modified by adjusting the synthesis parameters. Nanosheet zeolites have been extensively studied as catalysts in a wide range of reactions, such as methanol conversion, catalytic cracking, isomerization, alkylation, oxidation/reduction, and lignocellulose conversion. The modification of nanosheet zeolites, such as pillaring, has been shown to enhance their catalytic performance. This review provides a comprehensive overview of the recent progress in nanosheet zeolites, including the challenges and future outlook of nanosheet catalyst technologies.

Summary: This study investigates the impact of ligament gap in NiO mesoporous with different templates on the activity of rGO/NiO in alkaline hydrogen evolution reaction. It is found that the activity of the electrocatalyst is primarily determined by the size of ligament gap rather than the surface area. The results demonstrate that rGO/NiO prepared with KCC-1 template exhibits superior activity due to its larger ligament gap, despite having the smallest surface area. It is suggested that the accumulated hydrogen gas within the NiO mesoporous structure could elevate the internal electrode resistance and reduce overall catalytic activity.

Summary: In this study, the effect of solution pH in hydrothermal synthesis and post-annealing treatment on the photocatalytic performance of hexagonal prism ZnO without a seed layer was investigated. By adjusting the precursor molarity ratio, three samples with different solution pH values were obtained. The sample with a solution pH of 7.00 showed the highest photodegradation efficiency of methylene blue under UV irradiation. Post-annealing treatment at different temperatures changed the crystal orientation and morphology of the samples, resulting in improved photocatalytic activity.

Summary: Mesopores were successfully generated through desilication method and the amount of mesopore was controlled by adjusting OSDA contents in the zeolite framework via partial detemplation. The relative crystallinity remained the same for all the desilicated samples compared to their parents. Furthermore, the occluded OSDA within ZSM-48 may have another role in desilication process, affecting the density and distribution of the acid site. The improved catalytic performance of mesoporous samples, as shown by the lower observed activation energy (Eobs) in LDPE pyrolysis test, further confirmed the benefits of mesopores in enhancing molecule diffusion.

Summary: We synthesized a mesoporous NiFe2O4/MXene nanocomposite for the alkaline HER, which showed significantly improved electrocatalytic activity compared to individual NiFe2O4 and MXene components. The mesoporous structure provided a large surface area and enhanced mass transport, while the incorporation of MXene improved charge transfer kinetics. DFT calculations revealed more favorable H atom adsorption and activation on the NiFe2O4 surface. This study highlights the potential of templated mesoporous nanocomposites for efficient electrocatalysts in alkaline HER and contributes to renewable energy technologies.
