There is an urgent need to reduce global greenhouse gas emissions, yet date the decarbonization of transportation industry has been slow and particular difficulty. While fossil fuel replacements such as biodiesel may aid transition a less polluting society, production at industrial scales required currently heavily dependent on chemical catalysis. Conventional two-step homogenous routes require...

Fuel cells have attracted extensive attention due to their high conversion efficiency and environmental friendliness. However, wider application is limited by the poor activity cost of platinum (Pt), which widely used as cathode catalyst overcome slow kinetics associated with oxygen reduction reaction (ORR). Pt-based composites one-dimensional (1D) nanoarchitectures demonstrate great advantages...

The influence of Mo particle size on the catalytic activity and product selectivity of alkalized MoS2 nanocatalysts has been investigated. Nanocatalysts are prepared using a microemulsion technique with water-to-surfactant ratios of 1-12. Three different techniques, including XRD, TEM, and hydrogen chemisorption were used to determine the molybdenum average particle size and their activity and ...

Steam reforming of methanol is one of the promising processes for on-board hydrogen production used in fuel cell applications. Due to the time and energy consuming issues associated with conventional synthesis methods, in this paper a quick, facile, and effective microwave-assisted solution combustion method was applied for fabrication of copper-based nanocatalysts to convert methanol to hydrog...

The catalytic performance of Ni-Al, Mg-Al, and Co-Ni LDHs as novel nanocatalysts was evaluated in the oxidation of toluene. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). The XRD and FTIR approved the structure and functional groups of the LDH, respectively. Also, the presence of cations with dif...

Biodiesel is a fuel that has numerous benefits over traditional petrodiesel. The transesterification process the most popular method for biodiesel production from various sources, categorized as first, second and third generation depending on source. subject to variety of factors can be taken into account improve yield. One catalyst type concentration, which plays significant role in sources. A...
