摘要:There is provided a photocatalyst for the direct synthesis of methanol from methane and carbon dioxide. The photocatalyst comprises an AuPd alloy nanoparticles dispersed on a support comprising GaN, InN, AlN, BN, TlN, GaP, InP or a combination thereof. The AuPd alloy nanoparticles are uniformly dispersed on the support such that at least 90% of the AuPd alloy nanoparticles are positioned at a distance of from 1 nm to 15 nm from other AuPd alloy nanoparticles. There is also provided a method of synthesizing methanol from methane and carbon dioxide with a photocatalyst comprising a transition metal dispersed on a support comprising GaN, InN, AlN, BN, TlN, GaP, InP or a combination thereof.

标题:Synthesis of polycyclic aromatic hydrocarbons
发明人：JOHNSON RICHARD PETER; THAMATAM RAJESH
权利人:THE UNIV OF NEW HAMPSHIRE
摘要:The present invention relates to the synthesis of polycyclic aromatic compounds. Compounds such as terrylene or quaterrylene may now be prepared in relatively high yield by reaction of naphthalene or perylene via Scholl-type coupling in the presence of a superacid and an oxidant in an inert solvent.

标题:Green hydrogen, synthesis gas with a reduced nitrogen content, and flue gas for the synthesis of ammonia and urea
发明人：GORVAL EVGENI

摘要:The invention relates to the synthesis of urea from ammonia and carbon dioxide, wherein the hydrogen required for ammonia synthesis is obtained both by steam reforming of feed natural gas (grey hydrogen) and by electrolysis of water using electricity from renewable energy sources (green hydrogen). As the proportion of green hydrogen increases, the amount of carbon dioxide formed in the synthesis gas during steam reforming is no longer sufficient for the synthesis of urea. Therefore, flue gas, which is formed during the combustion of a fuel gas composed of fuel natural gas and combustion air and which also contains carbon dioxide, is additionally used. The oxygen formed during the electrolysis of water is introduced into the flue gas, and the modified flue gas is fed to a secondary reformer; and/or the fuel natural gas is combusted together with combustion air and the oxygen formed during electrolysis. Excess nitrogen is preferably separated from the synthesis gas before it is used for the synthesis of ammonia.
