摘要:A process for producing an ester is disclosed comprising contacting a gaseous reactant containing at least one organic hydroxy compound and a mixture of carbon monoxide and hydrogen with an ester synthesis catalyst of the formula MaAbRuCucNzOx wherein M is selected from the group consisting of Ce, Cr, Fe, Mn and mixtures thereof, A is an alkali metal, alkaline earth metal or mixture thereof, a is from 0 to about 1, b is from 0.002 to about 10, c is from 0.2 to about 20, z is from 0 to about 196 by weight, x is the number of oxygens needed to fulfill the valence requirements of the other elements. The organic hydroxy compound can be provided separately or formed by contacting a mixture of carbon monoxide and hydrogen with an alcohol synthesis catalyst at an elevated temperature and pressure. The alcohol synthesis catalyst and ester synthesis catalyst can be in tandem or mixed.

摘要:A method for hydrogen (H2) generation includes reacting sodium borohydride (NaBH4) with water in the presence of a graphite-phase carbon nitride copper oxide and magnesium aluminum oxide (g-C3N4@CuO/MgAl2O4) nanocomposite to hydrolyze the sodium borohydride and generate hydrogen. The g-C3N4@CuO/MgAl2O4 nanocomposite comprises a graphite-phase carbon nitride (g-C3N4) in an amount of 5 to 15 percent by weight (wt. %), copper oxide in an amount of 3 to 7 wt. %, and magnesium aluminum oxide (MgAl2O4) in an amount of 80 to 90 wt. % based on a total weight of the g-C3N4@CuO/MgAl2O4 nanocomposite.
