Solid composite fuel from low-grade raw (technological aspect)

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The urgency of the discussed issue is caused by the need to involve local resources of low-grade raw materials in the fuel and energy balance. The main aim of the study is to summarize the results of heat-technology processing of low-grade raw materials,

Tailoring the Microstructure of B‐Cation Octahedra in Halide Double Perovskites for Efficient Selective CO2‐to‐CO Photoreduction

Advanced Functional Materials, EarlyView.
The thermodynamic obstacle of CO2‐to‐CO conversion over metal halide perovskite photocatalysts is addressed by modulating the local electronic structure. A 13‐fold improvement in selective CO2 photoreduction to CO is achieved, with ≈100% selectivity.

Illuminating the Origins of Ferroelectric‐Induced Photocurrent and Hole Lifetime Enhancement in BaTiO3 Photoanodes

Advanced Functional Materials, EarlyView.
The use of ferroelectric polarization to enhance photocatalytic and photoelectrocatalytic activity is an innovative, and increasingly studied route to improve the spatial separation of charge carriers and therefore enhance catalytic efficiency. These results demonstrate how the intrinsic properties of a ferroelectric film can extend charge carrier ...

Engineering Active CeO2/Fe3C Interfacial Sites to Generate High‐Charge‐Density Fe for Enhanced Oxygen Reduction Reaction Efficiency

Advanced Functional Materials, EarlyView.
A well‐modulated CeO2/Fe3C heterostructure is successfully constructed. The electron redistribution induced by CeO2 not only enhances the formation energy of Fe vacancies and hinders the dissolution of Fe but also reduces the energy barrier of the ORR.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Self‐supportive Three‐Way Photoelectrochemical System Achieving Uranium Recycling, Organic Oxidation, and Electricity Generation in Complex Waters

Advanced Functional Materials, EarlyView.
A self‐sustaining solar photoelectrochemical cell (SS‐PEC) is developed to recover uranium from aqueous UO22+ with concurrent organic oxidation and electricity production. The monolithical photoanode directly captures electrons from organic compounds, leading to the oxidation of organic compounds and the decomposition of uranium‐organic complexes ...

Au@h‐BN Core–Shell Nanostructure as Advanced Shell‐Isolated Nanoparticles for In Situ Electrochemical Raman Spectroscopy in Alkaline Environments

Advanced Functional Materials, EarlyView.
This study demonstrates the stability and Raman signal enhancement effects of Au@h‐BN nanoparticles in an alkaline electrolyte on. A comparison between conventional SiO2 and h‐BN shells reveals that the h‐BN core‐shell structure provides superior stability and enhanced Raman intensity over multiple cyclic voltammetry cycles.
