In general, each hydrogen production process can be classified into the following colors according to the CO2 emissions, and the description of each process is summarized in Table 2: Gray (high CO2), Blue (low CO2), Turquoise (CO2 free), Green (carbon free). Table 2. Comparisons of ...

It is a challenge to simultaneously retain high performance and green synthesis process of polyurethane (PU). Here, a PU was synthesized completely using ethanol as solvent based on the chain extender, hexanediamine (HMD), with higher reactivity towards isocyanate groups than ethanol. Chemical compon...
Green hydrogen is being produced by electrolysis, which is a process that uses electricity to split water molecules (H2O) into hydrogen (H2) and oxygen (O2). When electrolysis is combined with renewable electricity, the production of fuels and chemicals can be decoupled from fossil resources, pav...
Hydrogen gas production from cellulose was investigated using an integrated hydrogen production process consisting of a dark fermentation reactor and micro... A Wang,D Sun,G Cao,... - 《Bioresource Technology》 被引量: 222发表: 2011年 Green process for hydrogen production from cellulose derivative...
Many fabrics are bleached with hydrogen peroxide or chlorine-containing compounds in order to remove their natural color, and if the fabric is to be sold white and not dyed, optical brightening agents are added [37]. Dyeing is the aqueous application of color to the textile substrates, mainly...
Two sources of endogenous H2O2 in Escherichia coli Mechanisms of hydrogen peroxide generation in Escherichia coli were investigated using a strain lacking scavenging enzymes. Surprisingly, the deletion of m... S Korshunov,JA Imlay - 《Molecular Microbiology》 被引量: 134发表: 2010年 加载更多研究...
Ozonation with hydrogen peroxide (O3/H2O2) Alkaline ozonation (O3/HO−) 3.2.1 Sonochemical Oxidation Methods Advanced oxidation processes generally uses UV light in the presence of H2O2, O3, Fenton reagents, or a catalyst to generate highly reactive oxidizing agents to degrade recalcitrant chemical...
Hydrogen is a type of clean energy which has the potential to replace the fossil energy for transportation, domestic and industrial applications. To expand
process: they consume carbohydrates and other organic materials, using oxygen synthesized by plants to form water, carbon dioxide, and energy. The process that removes hydrogen atoms (containing electrons) from the carbohydrates and passes them to the oxygen is an energy-yielding series of reactions...
