This article reports ZnO‐assisted growth of three‐dimensional (3D) dendritic hexapods of tin(II) oxyhydroxide (Sn6O4(OH)4) from acidic aqueous solution of stannous sulfate (SnSO4). Each Sn6O4(OH)4 hexapod has four long horizontally and two short vertically oriented dendritic branches. The formation of Sn6O4(OH)4 can be ascribed to the presence of ZnO whose surfaces are rich in hydroxyl groups. When covered by SnSO4 acidic aqueous solution, a large amount of hydroxyl groups is released from ZnO surfaces and further promotes the hydrolysis of SnSO4 towards Sn6O4(OH)4. Time‐dependent shape evolution from the nanoparticles‐assembled hierarchical octahedra to the 3D dendritic hexapods has been explored. The growth of Sn6O4(OH)4 3D dendritic hexapods has been explained based on a nanoparticle‐mediated, diffusion‐limited dendritic growth mechanism. Sn6O4(OH)4 can be selectively converted to semiconducting SnO or SnO2 for potential sensing and catalytic applications.

“…Table 1 reports different amine-modified INAD adsorbents employed for removing various pollutants from water. Bouazizi et al employed several types of amine such as APTES, PAMAM, DEA, and others for the surface functionalization of porous materials [18,20,22,24]. Results obtained in water treatment showed that covalent grafting of amine onto the adsorbent is of great interest to increase the adsorption uptake and the number of recycling cycles.…”

“…functionalization via the chemical grafting of amines has increased the number of useful activated sites for adsorption and capture of toxic molecules. Metal oxides based on copper oxide (CuO), zinc oxide (ZnO), and tin oxide (SnO2) modified via chemical grafting of amines possess superior electrical, optical, catalytic, and antibacterial properties not attainable via their metallic alloy and monometallic counterparts [17,21,[24][25][26].…”

“…The enhanced stability and surface compatibility of amine with porous materials can be achieved through the kinetic trapping of amines surrounding the porous materials. However, further efforts are still required to fully elucidate the intimate relationship between amine-modified INAD structures and their adsorption of wastewater pollutants and their antibacterial properties [19][20][21][22][23][24][25][26][27][28][29][30][31][32]. The goal of this review is to provide a view of the surface functionalization via grafting of amines and their adsorption behavior in water treatment.…”

Advances in Amine-Surface Functionalization of Inorganic Adsorbents for Water Treatment and Antimicrobial Activities: A Review

In the last decade, adsorption has exhibited promising and effective outcomes as a treatment technique for wastewater contaminated with many types of pollutants such as heavy metals, dyes, pharmaceuticals, and bacteria. To achieve such effectiveness, a number of potential adsorbents have been synthesized and applied for water remediation and antimicrobial activities. Among these inorganic adsorbents (INAD), activated carbon, silica, metal oxide, metal nanoparticles, metal–organic fibers, and graphene oxide have been evaluated. In recent years, significant efforts have been made in the development of highly efficient adsorbent materials for gas and liquid phases. For gas capture and water decontamination, the most popular and known functionalization strategy is the chemical grafting of amine, due to its low cost, ecofriendliness, and effectiveness. In this context, various amines such as 3-aminopropyltriethoxysilane (APTES), diethanolamine (DEA), dendrimer-based polyamidoamine (PAMAM), branched polyethyleneimine (PEI), and others are employed for the surface modification of INADs to constitute a large panel of resource and low-cost materials usable as an alternative to conventional treatments aimed at removing organic and inorganic pollutants and pathogenic bacteria. Amine-grafted INAD has long been considered as a promising approach for the adsorption of both inorganic and organic pollutants. The goal of this review is to provide an overview of surface modifications through amine grafting and their adsorption behavior under diverse conditions. Amine grafting strategies are investigated in terms of the effects of the solvent, temperature, and the concentration precursor. The literature survey presented in this work provides evidence of the significant potential of amine-grafted INAD to remove not only various contaminants separately from polluted water, but also to remove pollutant mixtures and bacteria.

“…In order to possess high rates of hydrogen sorption and desorption, advanced hydrogen storage materials should have optimal elemental and phase composition. Additionally, they should accumulate a large amount of hydrogen and be cyclically stable [7][8][9][10][11]. In the matrix, metal hydrides have a high bulk density of hydrogen atoms, a wide range of operating pressures and temperatures, catalytic activity, and are the most used materials for hydrogen storage [12][13][14][15][16][17][18][19][20].…”

Currently, standard samples with high hydrogen concentrations that meet the requirements of hydrogen extraction in an inert atmosphere are not currently available on the market. This article describes the preparation of Ti-H standard samples and the calibration of RHEN602, a hydrogen analyzer, using LECO (LECO, Saint Joseph, MI, USA). Samples of technically pure titanium alloy were chosen as the material for sample production. The creation procedure includes five main steps: sample preparation (polishing to an average roughness of 0.04 μm using sandpaper), annealing, hydrogenation, maintenance in an inert gas atmosphere, and characterization of the samples. The absolute hydrogen concentration in the samples was determined by two methods: volumetric and mass change after the introduction of hydrogen. Furthermore, in-situ X-ray diffraction, temperature programmed desorption (TPD) analysis, and thermogravimetric analysis were used during measurements to investigate the phase transitions in the samples. As a result of this work, a series of calibration samples were prepared in a concentration range up to 4 wt % hydrogen, optimal parameters for measuring high concentrations of hydrogen. The calibration line was obtained and the calibration error was 10%.
