Nanosize Nickel ferrite (NiF) was synthesized by the co-precipitation methods, and its effect as a 5% mass additive studied on thermal decomposition of micrometer nanometer size NTO. In presence NiF additive, peak temperature NTO decreased from 276.36 to 260.18 °C that nanoNTO 261.38 258.89 (β = 10 min−1). The kinetics parameters confirm catalytic activity for NTO, nNTO such activation energy (...

Both photogenerated carrier and photothermal effect enhanced electrochemical urea-assisted hydrogen generation on a Ni-NiO/Nickel Foam catalyst.

The present XANES study aims at elucidating the roles of carbon deposits and metal sulfides in the catalyst deactivation in steam reforming reactions with the presence of sulfur. CeO(2)-Al(2)O(3)-supported Ni and Rh-based catalysts were tested in steam reforming of liquid hydrocarbon fuel containing 350 ppm sulfur for H(2) production at 800 degrees C. The Rh catalyst demonstrated much better su...

The solar-driven reduction of carbon dioxide to value-added chemical fuels is a longstanding challenge in the fields of catalysis, energy science, and green chemistry. In order to develop effective CO2 fixation, several key considerations must be balanced, including (1) catalyst selectivity for promoting CO2 reduction over competing hydrogen generation from proton reduction, (2) visible-light h...

a sodium dodecyl sulfate modified carbon paste electrode (sds/cpe) was developed in this work based on the surface modification method. the modified electrode was prepared by immersing sds/cpe in a nickel nitrate solution. this electrode showed a strong accumulation ability toward nickel ions. then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 v (vs. ...

Strong and versatile carbon nanotubes (CNTs) are finding new applications in improving conventional polymer-based fibers. Nanotube-reinforced composites could ultimately provide the foundation for a new class of strong and lightweight fibers with properties such as electrical and thermal conductivity unavailable in current fibers. A recent research has discovered that the best type of nanotube ...
