The H2/CO2 gas separation is extremely emerging both for the production of H2 which useful as an energy source/fuel due to high content per unit weight and capturing CO2 emissions that cause global warming climate change. adsorption method has come fore because it requires less process than other technologies a reduced environmental impact. In order determine promising adsorbent, really time-co...

Global warming and environmental degradation have stimulated the drive towards capture of large point source carbon emissions reducing high energy intensity industrial processes. Mixed membranes infused with porosity silica sodalite are potential useful for pre-combustion CO2 capture. However, development quality mixed matrix is a challenge. In this study, (SSOD) polysulfone (PSF) were develope...

Background Sulfur-deprived cultivation of Chlamydomonas reinhardtii, referred as "two-stage culture" transferring the cells from regular algal medium to sulfur-deplete one, has been extensively studied to improve photobio-H2 production in this green microalga. During sulfur-deprivation treatment, the synthesis of a key component of photosystem II complex, D1 protein, was inhibited and improved ...

One alternative for the storage and transport of hydrogen is blending a low amount (up to 15 or 20%) into existing natural gas grids. When demanded, can be then separated, close end users using membranes. In this work, composite alumina carbon molecular sieves membranes (Al-CMSM) supported on tubular porous have been prepared characterized. Single permeation studies showed that H2/CH4 separatio...

The immobilisation of molecular catalysts on semiconductors for solar fuel production is an attractive strategy to exploit electrocatalysts in a heterogeneous photocatalytic environment. Efficient H2 production in such hybrid systems requires effective electronic coupling between the light harvesting unit and the electrocatalyst. Current examples based on non-precious metal complexes include Co...

H2 is an important energy carrier for replacing fossil fuel in the future due to its high density and environmental friendliness. As a sustainable H2-generation method, photocatalytic production by water splitting has attracted much interest. Here, oil-soluble ZnxCd1–xS quantum dot (ZCS QD) with uniform particle size distribution were prepared hot-injection method. However, no H2-production act...
