In this study, we report the synthesis of iron oxide nanoparticles (FeONPs) using micro-emulsion-hydrothermal method. By adjusting the synthesis temperature, we successfully produced FeO nanorods and nanospheres. In addition, the 2-octanol, and the surfactant cetyltrimethylammonium bromide served as a solvent in the synthesis process.

- This research focuses on converting waste methane into valuable syngas using customized nickel-zeolite catalysts, particularly examining 5 wt % nickel on various zeolite supports.
- Comprehensive characterization methods revealed that factors such as catalyst reducibility, type of zeolite support, and carbon deposit formation at high temperatures significantly affect methane conversion efficiency.
- The optimal catalyst, 5Ni-Z3, achieved over 92% conversion for methane and over 90% for carbon dioxide under ideal conditions, with experimental results closely matching predictions from simulations, confirming the effectiveness of the dry reforming process.
A novel nickel-molybdenum carbide-graphite nanofiber composite is introduced as an electrocatalyst for ethanol electrooxidation. The proposed nanofibers have been prepared by calcinating electrospun nanofibers composed of nickel acetate tetrahydrate, molybdenum chloride, and polyvinyl alcohol. The calcination process was conducted at different temperatures (700, 850, and 1000°C) under a nitrogen gas atmosphere with a heating rate of 2.

- The study focuses on using nickel (Ni) within different molecular sieve nanomaterials for the dry reforming of methane (DRM) to efficiently produce syngas, addressing global warming caused by greenhouse gases.
- The reduced 5Ni/CBV3024E catalyst showed the best performance, producing the highest hydrogen (H) output (44%) and achieving an optimal hydrogen to carbon monoxide (CO) ratio of 1.00 under specific conditions, despite having fewer initial active sites.
- The research demonstrated the effectiveness of optimizing catalytic conditions using techniques like central composite design, resulting in high yields of both hydrogen (91.92%) and carbon monoxide (89.16%) and
Perfluoroalkyl carboxylic acids (PFCAs) are sub-class of perfluoroalkyl substances commonly detected in water matrices. They are persistent in the environment, hence highly toxic to living organisms. Their occurrence at trace amount, complex nature and prone to matrix interference make their extraction and detection a challenge.
