hydrogen as an ideal energy carrier can play a very important role in future energy systems for hydro-gen production can be used a variety of technologies and sources. one of the most promising methods for large-scale hydrogen production is thermo-chemical water decomposition using heat energy from nuclear, solar and other sources. the water splitting thermo-chemicals cycles are processes where...

the process of ethylene production from ethane dehydrogenation is one of the interesting processes in the field of conversion the petroleum light gases to the valuable products. in this process, the outlet gaseous product is a combination of ethylene, ethane and hydrogen. effective separation techniques are required for separation of ethylene from unreacted ethane. here a new adsorbent approach...

The organic-inorganic composite g-C3N4eSrTiO3:Rh was prepared for the first time as a photocatalyst for hydrogen production and the resulting hydrogen evolution rate under visible light irradiation from aqueous methanol solution was measured. A high hydrogen evolution rate of 223.3 mmol h 1 was achieved by using 0.1 g of as-prepared photocatalyst powder comprised of 20 wt.% g-C3N4 80 wt.% SrTiO...

Ethanol concentration dependence of photoinduced charge separation between zinc tetraphenylporphyrin (ZnTPP) and duroquinone (DQ) in benzonitrile was studied by nanosecond laser flash photolysis. Acceleration of the photoinduced charge separation reaction rate by hydrogen bonding between DQ anion radical and ethanol was observed. A simple analysis in the framework of the Marcus theory indicated...
