    Abstract: The present invention provides a class of catalyst compounds that can safely and effectively release hydrogen gas from a chemical substrate without producing either noxious byproducts or byproducts that will deactivate the catalyst. The present invention provides catalysts used to produce hydrogen that has a satisfactory and sufficient lifespan (measured by turnover number (TON)), that has stability in the presence of moisture, air, acid, or impurities, promote a rapid reaction rate, and remain stable under the reaction conditions required for an effective hydrogen production system. Described herein are compounds for use as catalysts, as well as methods for producing hydrogen from formic acid and/or a formate using the disclosed catalysts. The methods include contacting formic acid and/or a formate with a catalyst as described herein, as well as methods of producing formic acid and/or a formate using the disclosed catalyst and methods for generating electricity using the catalysts described herein.

    Abstract: Catalyst compositions comprising catalytic nanoparticles including copper distributed, dispersed on, or mixed with a promoter including magnesium oxide. Pre-catalyst compositions comprising nanoparticles including copper oxides or copper hydroxide distributed, dispersed on, or mixed with a promoter including magnesium oxide. The catalysts are used in a method of producing at least methyl formate and hydrogen by non-oxidative dehydrogenation of methanol, optionally comprising reducing a pre-catalyst in hydrogen at a select temperature to obtain a catalyst comprising catalytic nanoparticles including copper distributed, dispersed on, or mixed with a promoter including magnesium oxide, flowing a fluid composition containing at least methanol over the catalyst to produce methyl formate and hydrogen, and recovering one or more of the methyl formate and hydrogen. A method of preparing catalyst compositions is disclosed. Alternatively or in addition to copper, the catalytic metal can be palladium, nickel or platinum. Alternatively or in addition to magnesium oxide the promoter can comprise zinc oxide, zirconium oxide, silica, calcium oxide, strontium oxide, barium oxide, lanthanum III oxide, gallium oxide, alumina, cerium oxide, vanadium oxide, chromium oxide, titanium oxide, tin oxide, and combinations or mixtures thereof.

    Abstract: A cell for enhancing a lithium (Li) concentration in a stream includes a housing; a dense lithium selective membrane located in the housing and dividing the housing into a first compartment and a second compartment; a cathode electrode located in the first compartment; an anode electrode located in the second compartment; a first piping circuit fluidly connected to the second compartment and configured to supply a feed stream to the second compartment; a second piping circuit fluidly connected to the first compartment and configured to circulate an enrichment stream through the first compartment; and a power source configured to apply a voltage between the cathode electrode and the anode electrode to initiate an oxidative electrochemical reaction on the anode electrode and a reductive electrochemical reaction on the cathode electrode. The dense lithium selective membrane has a thickness less than 400 μm.
