The interaction of hydrogen molecules with clean and hydrogen-precovered surfaces has been studied using ab initio molecular dynamics simulations based on density functional theory. In particular, the dependence of the dissociative adsorption probability on the hydrogen coverage and the relaxation of hot hydrogen atoms after dissociation have been addressed. The simulations unravel the crucial ...

The increase in energy consumption is closely correlated with the continuous evolution of human society, which implies both depletion fossil fuels and pollution levels. One solution to these problems obtain electricity from renewable sources but also use alternative for car transportation. Within paper, there are presented necessary conditions design hydrogen gas stations accordance legal requi...

Small size molybdenum carbides (2.5 nm for MoC and 5.0 nm for Mo2C) with clean surface on graphene were prepared for efficient and stable hydrogen evolution reaction catalysts.

As a clean energy source and industrial material, hydrogen is very valuable. Electrolysis of water and chemical methods are well-known for producing hydrogen, however, all of these methods need additional energy supply. Besides highly energy cost, the chemical methods will lead to serious environment pollution. Compared with traditional methods, biological production of hydrogen has showed sign...

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...

Glycerol is a by-product of biodiesel obtained from biomass, accounting for 10% of the biodiesel production. In the context of a green economy, aiming for a reduction of the emission of atmospheric greenhouse gases emissions, the demand of biodiesel is expected to increase vastly, in parallel with a side glut supply of glycerol. Given the high cost of biodiesel compared with its fossil congener...
