标题:Phase Transitions As A Function Of Temperature In Bimgvox
摘要:Phase Transitions In Bimgvox,Bi2Mgxv1-Xo5.5-3X/2-Delta,Have Been Studied Using A Combination Of A.C. Impedance Spectroscopy,Differential Thermal Analysis And Variable Temperature X-Ray Powder Diffraction. Two Composition Regions Were Examined. In The First,Below X = 0.10,Phase Transitions Associated With The Alpha,Beta And Gamma-Phases Are Observed. In The Second Region Above X = 0.10 The Gamma' <----> Gamma Transition Is Clearly Observable. Trends In The Refined Unit Cell Parameters Were Particularly Indicative Of The Phase Transitions. The Results Are Compared To Those Obtained For Parent Compound Bi4V2O11-Delta.

标 题 :Photo-catalytic Systems for Production of Hydrogen

摘要:A system for splitting water and producing hydrogen for later use as an energy source may include the use of a photoactive material including PCCN and plasmonic nanoparticles. A method for producing the PCCN may include a semiconductor nanocrystal synthesis and an exchange of organic capping agents with inorganic capping agents. The PCCN may be deposited between the plasmonic nanoparticles and may act as photocatalysts for redox reactions. The photoactive material may be used in presence of water and sunlight to split water into hydrogen and oxygen. Production of charge carriers may be triggered by photo-excitation and enhanced by the rapid electron resonance from localized surface plasmon resonance of plasmonic nanoparticles. By combining different semiconductor materials for PCCN and plasmonic nanoparticles and by changing their shapes and sizes, band gaps may be tuned to expand the range of wavelengths of sunlight usable by the photoactive material. The system may include elements for collecting, transferring, and storing hydrogen and oxygen, for subsequent transformation into electrical energy.

摘要:A method comprising mixing a bismuth precursor, a vanadium precursor, and at least one metal dopant precursor together with a salt or salt mixture having a eutectic melting temperature of no greater than 680° C. to form a homogeneous mixture, which is heated to a temperature of from 550° C. to 700° C. to produce a molten state of the salt or salt mixture and to obtain a metal doped bismuth vanadium oxide product that is a derivative of Bi 4 V 2 O 11 , which is then cooled. The thus-produced metal doped bismuth vanadium oxide product is present in loose platelet form, with the platelets capable of being aligned such that their planes are substantially parallel to one another.

摘要:A method and composition for producing a photoactive material including photocatalytic capped colloidal nanocrystals (PCCN) and plasmonic nanoparticles are disclosed. The PCCN may include a semiconductor nanocrystal synthesis and an exchange of organic capping agents with inorganic capping agents. Additionally, the PCCN may be deposited between the plasmonic nanoparticles, and may act as photocatalysts for redox reactions. The photoactive material may be used in a plurality of photocatalytic energy conversion applications, such as water splitting and CO 2 reduction. By combining different semiconductor materials for PCCN and plasmonic nanoparticles, and by changing their shapes and sizes, band gaps may be tuned to expand the range of wavelengths of sunlight usable by the photoactive material. Higher light harvesting and energy conversion efficiency may be achieved.

摘要:A system employing sunlight energy for reducing CO 2 into methane and water is disclosed. The system may include the use of a photoactive material including plasmonic nanoparticles and photocatalytic capped colloidal nanocrystals (PCCN). A method for producing the PCCN may include a semiconductor nanocrystal synthesis and an exchange of organic capping agents with inorganic capping agents. Additionally, the PCCN may be deposited between the plasmonic nanoparticles, and may act as photocatalysts for redox reactions. The CO 2 reduction system may use inorganic capping agents that cap the surface of semiconductor nanocrystals to form PCCN, which may be deposited on a substrate and treated to form a photoactive material. The photoactive material may be employed in the system to harvest sunlight and produce energy necessary for carbon dioxide reduction. The system may also include elements necessary to collect and transfer methane, for subsequent transformation into electrical energy.
