Methods And Materials For The Thermochemical Production Of Hydrogen From Water

View page
US Patent:
20130266504, Oct 10, 2013
Filed:
Apr 2, 2013
Appl. No.:
13/855180
Inventors:
MARK E. DAVIS - PASADENA CA, US
BINGJUN XU - PASADENA CA, US
YASHODHAN BHAWE - PASADENA CA, US
Assignee:
CALIFORNIA INSTITUTE OF TECHNOLOGY - PASADENA CA
International Classification:
C01B 3/06
US Classification:
423579
Abstract:
The present invention is directed to a method of thermochemical forming H, O, or a combination thereof from water, said method comprising the steps of contacting a composition comprising a spinel-type transition metal oxide of formula MOwith an alkali metal carbonate bicarbonate, or mixture thereof in the presence of HO to form H, CO, and an alkali metal ion-transition metal oxide; hydrolytically extracting at least a portion of alkali metal ions from the alkali metal ion-transition metal oxide by the reaction with COand liquid HO; and thermochemically reducing the resulting oxidized-transition metal oxide. The thermochemical reduction of CObased on analogous methods is also disclosed.

Silver-Catalyzed Synthesis Of Amides From Amines And Aldehydes

View page
US Patent:
20130079556, Mar 28, 2013
Filed:
Jan 25, 2011
Appl. No.:
13/575150
Inventors:
Robert J. Madix - Lexington MA, US
Ling Zhou - Cambridge MA, US
Bingjun Xu - Cambridge MA, US
Cynthia M. Friend - Lexington MA, US
Cassandra G. Freyschlag - Colorado Springs CO, US
International Classification:
C07C 231/10
US Classification:
564215, 564123
Abstract:
The invention provides a method for producing amides via the reaction of aldehydes and amines with oxygen adsorbed on a metallic silver or silver alloy catalyst. An exemplary reaction is shown in Scheme 1 : (I), (II), (III)

Poly(Aryl Piperidinium) Polymers Including Those With Stable Cationic Pendant Groups For Use As Anion Exchange Membranes And Ionomers

View page
US Patent:
20210009726, Jan 14, 2021
Filed:
Sep 28, 2018
Appl. No.:
16/651622
Inventors:
- Newark DE, US
Keda Hu - Newark DE, US
Junhua Wang - Newark DE, US
Lan Wang - Newark DE, US
Bingjun Xu - West Chester PA, US
Yun Zhao - Newark DE, US
International Classification:
C08F 26/08
B01J 41/14
H01M 8/10
Abstract:
Poly(aryl piperidinium) polymers with pendant cationic groups are provided which have an alkaline-stable cation, piperidinium, introduced into a rigid aromatic polymer backbone free of ether bonds. Hydroxide exchange membranes or hydroxide exchange ionomers formed from these polymers exhibit superior chemical stability, hydroxide conductivity, decreased water uptake, good solubility in selected solvents, and improved mechanical properties in an ambient dry state as compared to conventional hydroxide exchange membranes or ionomers. Hydroxide exchange membrane fuel cells comprising the poly(aryl piperidinium) polymers with pendant cationic groups exhibit enhanced performance and durability at relatively high temperatures.

US Patent:
20150056129, Feb 26, 2015
Filed:
Nov 5, 2014
Appl. No.:
14/533445
Inventors:
- PASADENA CA, US
BINGJUN XU - PASADENA CA, US
International Classification:
C01B 3/06
C01B 13/02
US Classification:
423579
Abstract:
The present disclosure is directed to methods of catalytically reducing carbon dioxide, each method comprising: contacting a composition comprising a spinel-type transition iron oxide with an alkali metal carbonate, bicarbonate, or mixture thereof at a first temperature to form CO, and an alkali metal ion-transition metal oxide; hydrolytically extracting at least a portion of alkali metal ions from the alkali metal ion-transition metal oxide by the reaction with COand liquid HO at a second temperature; and thermochemically reducing the transition metal composition of the second step at a third temperature, with the associated formation of O.
