Unique hierarchical SiO2@ZnIn2S4 marigold flower like nanoheterostructure for solar hydrogen production

Hydrogen Production Using Solar Energy

The objective of this project is to create clean fuel for transportation using hydrogen powered by solar energy. Hydrogen has been generated by solar photovoltaic (PV) array and then collected for data analysis to demonstrate efficiency of the hydrogen production in all the steps of the experiment. The hydrogen produced from the electrolysis process was either stored in a metal hydride canister...

Hydrogen Production By Solar Beam

Various methods of water-splitting with use of solar energy are reviewed and compared to each other. Direct thermal method has the highest efficiency, but the difficulty is the heat-resisting materials. Thermochemical method is pro­ mising if the corrosion-resisting materi­ als are found. Electrolytic method is tra­ ditional, but the hybrid system combined with thermochemical and/or photochemic...

Investigation of Sour Natural Gas Decomposition in a Nozzle-type Solar Reactor for Hydrogen Production

One-Dimensional Electrolyzer Modeling and System Sizing for Solar Hydrogen Production: an Economic Approach

In this paper, a solar based hydrogen production in the city of Tehran, the capital of Iran is simulated and the cost of produced hydrogen is evaluated. Local solar power profile is obtained using TRNSYS software for a typical parking station in Tehran. The generated electricity is used to supply power to a Proton Exchange Membrane (PEM) electrolyzer for hydrogen production. Dynamic nature of s...

Highly Efficient Photocatalytic Hydrogen Production of Flower-like Cadmium Sulfide Decorated by Histidine

Morphology-controlled synthesis of CdS can significantly enhance the efficiency of its photocatalytic hydrogen production. In this study, a novel three-dimensional (3D) flower-like CdS is synthesized via a facile template-free hydrothermal process using Cd(NO3)2•4H2O and thiourea as precursors and L-Histidine as a chelating agent. The morphology, crystal phase, and photoelectrochemical performa...
