标题:Cation Size And Anion Anisotropy In Structural Chemistry Of Metal Borohydrides. The Peculiar Pressure Evolution Of Rbbh4
摘要:The Pressure Evolution Of Rbbh4 Has Been Characterized By Synchrotron Powder X-Ray Diffraction And Raman Spectroscopy Up To 23 Gpa. Diffraction Experiments At Ambient Temperature Reveal Three Phase Transitions,At 3.0,10.4,And 18 Gpa (At 2.6,7.8,And Similar To 20 Gpa From Raman Data),At Which The Space Group Symmetry Changes In The Order Fm-3M(Z=4)-> P4/nmm(2)-> C222(2)-> /-42M(4). Crystal Structures And Equations Of State Are Reported For All Four Phases. The Three High-Pressure Structure Types Are New In The Crystal Chemistry Of Borohydrides. Rbbh4 Polymorphs Reveal High Coordination Numbers (Cns) For Cation And Anion Sites,Increasing With Pressure From 6 To 8,Via An Intermediate 4 + 4 Coordination. Different Arrangements Of The Tetrahedral Bh4 Group In The Rb Environment Define The Crystal Symmetries Of The Rbbh4 Polymorphs. The Structural Evolution In The Mbh4 Series Is Determined By The Cation'S Size,As It Differs Drastically For M = Li (Cns = 4,6),Na (Cn = 6),And Rb. The Only Structure Common To The Whole Mbh4 Family Is The Cubic One. Its Bulk Modulus Linearly Decreases As The Ionic Radius Of M Increases,Indicating That The Compressibility Of The Material Is Mainly Determined By The Repulsive Bh4 Center Dot Center Dot Center Dot Bh4 Interactions.

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.

摘要:A method for producing isolatable and dispersible graphene sheets, wherein the graphene sheets may be tailored to be soluble in aqueous, non-aqueous or semi-aqueous solutions. The water soluble graphene sheets may be used to produce a metal nanoparticle-graphene composite having a specific surface area that is 20 times greater than aggregated graphene sheets. Graphene sheets that are soluble in organic solvents may be used to make graphene-polymer composites.
