Synthesis, characterization, and physicochemical properties of Zn-based metal-organic frameworks: Nd-doping effects and comparative analysis of microwave vs. hydrothermal techniques Hatem A. Mahmoud, Lobna Abdel-Mohsen E. Nassr, Tarek T. Ali, Esraa A. A. Mahmoud, Ibrahim M. A. Mohamed Journal of Sol Gel Science and Technology, 2026 This study explores the synthesis and characterization of Nd-doped Zn-based metal-organic frameworks (MOFs) via microwave (Zn-MOF-M) and hydrothermal (Zn-MOF-A) methods. Nd incorporation influenced structural and physicochemical properties including reduced thermal stability and surface area as shown by TGA and BET analyses. The BET surface area of Zn-MOF-M decreased from 41.0 m 2 /g to 19.3 m 2 /g after Nd doping, while Zn-MOF-A showed a decrease from 15.6 m 2 /g to 9.98 m 2 /g. TGA revealed earlier decomposition in Zn/Nd-MOF-M (at 259 °C) compared with its pristine counterpart (at 409 °C), whereas the hydrothermal series retained higher stability up to 435 °C. XPS confirmed elemental changes such as decreased Zn content (from 9.54% in Zn-MOF-M to 8.34% in Zn/Nd-MOF-M) and altered bonding environments of oxygen and nitrogen. These results highlight the impact of Nd-doping and synthesis technique on MOF performance which could offer insights into the tunability of MOF properties for contribution to materials chemistry and solid-state physics.

Nickel oxide nanoparticles catalyst for enhancing green hydrogen production: effect of preparation conditions Hatem A. Mahmoud, Aya Adel A. Ali, Tarek T. Ali, Bahaa M. Abu-Zied BMC Chemistry, 2025 This work focused on the synthesis of nickel oxide under varying hydrothermal conditions as a non-precious and efficient catalyst for NaBH 4 hydrolysis to generate hydrogen. The structural, morphological, and textural features of the calcined samples were characterized using X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and N 2 -physisorption techniques. XPS analysis confirmed the presence of Ni 2+ and Ni 3+ species, with varying Ni 3+ /Ni 2+ ratios across the samples. The NH-200 samples showed the highest hydrogen generation rate, approximately 1290 at 323 K, attributed to the enhanced redox behavior of Ni 3+ ions. N 2 -adsorption results revealed mesoporous structures with distinct surface areas and pore characteristics. The catalytic performance was evaluated at 35–50 °C, showing enhanced activity with increasing temperature and NaBH 4 concentration (up to 4.5 wt.%). Activation energies were found to be below 59 kJ mol −1 . The catalyst maintained good stability over five consecutive cycles with only a slight performance decline. These findings confirm that NiO is a cost-effective, active, and reusable catalyst for hydrogen generation via NaBH 4 hydrolysis.
Physicochemical and structural characterization of novel praseodymium and neodymium-incorporated TiO2 for photocatalytic application Hatem A. Mahmoud, Tarek T. Ali, Shereen A. E. Nasr, Esraa A. A. Mahmoud, Lobna A. E. Nassr, et al. Journal of the Korean Ceramic Society, 2025 Novel photocatalytic metal–organic framework (MOF) materials are an exciting research topic. However, the lack of investigating rare-earth doped semiconductor as well as understanding their physicochemical and structural characterization will prevent commercial or industrial applications. To overcome this obstacle, this study investigates the physicochemical and structural characterization of novel applied Titania-based materials synthesized via MOF strategy for photodegradation of methyl orange (MO). The studied materials are TiO2, Pr-doped TiO2 (Pr@TiO2), and Nd-TiO2 (Nd@TiO2) and applied as promising photocatalysts. The synthesized photocatalysts were prepared via metal–organic framework strategy and characterized by Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), and X-ray Photoelectron Spectroscopy (XPS). SEM analysis revealed that only Nd resulted in smaller, more uniform particle sizes. XRD patterns confirmed the retention of the anatase phase in the case of Nd-modification, indicating successful lattice distortions. XPS results showed the chemical existence of Pr and Nd, increased oxygen vacancies, and surface hydroxyl groups, essential for enhanced photocatalytic activity. Photodegradation studies demonstrated that both Pr-TiO2 and Nd-TiO2 exhibited better performance compared to TiO2 without Pr or Nd, following pseudo-first-order kinetics. These findings highlight the potential of Pr and Nd modification in the TiO2 photocatalysts for efficient environmental remediation, particularly in the treatment of dye-containing wastewater.
Combustion Synthesis of Ag Nanoparticles and Their Performance During NaBH4 Hydrolysis Bahaa M. Abu-Zied, Tarek T. Ali, Lamia Adly Catalysis Letters, 2024 Due to their tremendous industrial, environmental, and biological applications, research focusing on the synthesis and applications of silver nanoparticles (Ag NPs) has attracted increased interest from researchers over the past two decades. Their structural as well as textural properties can be easily tuned depending on the synthesis protocol utilized. Combustion synthesis has received increased attention as a one-pot route for the synthesis of a wide spectrum of nanomaterials. In this study, we present the results of synthesizing Ag NPs employing urea as a combustion fuel. The effect of the temperature of calcination on the formation and structural features of Ag NPs has been checked over the 400–700 °C temperature range. The characterization of the synthesized Ag NPs has been performed using XRD, SEM, TEM, and XPS techniques. It was found that Ag NPs, with a crystallite size of 40 nm, start to form at around 400 °C. Conducting the calcination at the 500–700 °C range results in the persistence of the obtained Ag NPs. Moreover, the obtained nanomaterials are characterized by a membrane-like morphology. The activity performance of the synthesized Ag NPs was examined for the hydrolysis of sodium borohydride (NaBH4) over a temperature range of 35–50 °C. Increasing the calcination temperature has led to a decrease in the activity of the Ag NPs during the NaBH4 hydrolysis. Graphical Abstract
