TL;DR: Molecular compositions of dissolved organic matter (DOM) in leachate concentrate, as well as changes after anaerobic/aerobic biodegradation and coagulation with salts, were characterized using electrospray ionization (ESI) coupled with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS).
Abstract: Landfill leachate concentrate is a type of refractory organic wastewater with high environmental risk. Identification of refractory components and insights into the molecular transformations of the organics are essential for the development of efficient treatment process. In this report, molecular compositions of dissolved organic matter (DOM) in leachate concentrate, as well as changes after anaerobic/aerobic biodegradation and coagulation with salts, were characterized using electrospray ionization (ESI) coupled with Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). DOM in leachate concentrate were more saturated and less oxidized with more nitrogen and sulfur-containing substances (accounting for 50.0%), comparing with natural organic matter in Suwannee River. Selectivity for different classes of organics during biodegradation and coagulation processes was observed. Substances with low oxidation degree (O/C < 0.3) were more reactive during biodegradation process, leading to the f...

TL;DR: Owing to the synergy of the HIFs and the electronic effect of the Pt-Ni alloy, the as-prepared CNC and HOH Pt- Ni alloy NCs exhibited excellent catalytic properties for the electrooxidation of methanol and formic acid, as well as for the oxygen reduction reaction (ORR).
Abstract: The shape-controlled synthesis of multicomponent metal nanocrystals (NCs) bounded by high-index facets (HIFs) is of significant importance in the design and synthesis of high-activity catalysts. We report herein the preparation of Pt-Ni alloy NCs by tuning their shape from concave-nanocubic (CNC) to nanocubic and hexoctahedral (HOH). Owing to the synergy of the HIFs and the electronic effect of the Pt-Ni alloy, the as-prepared CNC and HOH Pt-Ni alloy NCs exhibited excellent catalytic properties for the electrooxidation of methanol and formic acid, as well as for the oxygen reduction reaction (ORR).

TL;DR: In this article, a tentative mechanism for the enhanced photocatalysis of the SnO 2 /ZnO/TiO 2 composite catalyst has been proposed, which could be attributed to the increased separation of the charge carriers, which depress the charge pair recombination and prolonged the electron lifetime in the composite structure.

TL;DR: Z-scheme-type photocatalysts with two photochemical systems of graphic-C3N4 and anatase TiO2 (A-TiO2) nanocrystals combined with Au nanoparticles (NPs) were successfully fabricated in this article.
Abstract: Z-scheme-type photocatalysts with two photochemical systems of graphic-C3N4 (g-C3N4) and anatase TiO2 (A-TiO2) nanocrystals combined with Au nanoparticles (NPs) [(Au/A-TiO2)@g-C3N4] were successfully fabricated. The surface heterojunction between coexposed {001} and {101} facets in A-TiO2 nanocrystals improves separation efficiency of photoelectrons and holes. Supported Au NPs gather and transfer the stimulated electrons originated from A-TiO2 to g-C3N4. Wrapped g-C3N4 nanosheets can not only trap the photoelectrons, but also its surface π bond can improve adsorption capabilities for CO2. (Au/A-TiO2)@g-C3N4 catalysts with enriched surface photoelectrons and CO2 exhibit high photocatalytic activity for visible-light-driven conversion of CO2, i.e., the formation rates of CH4 and CO over (Au/A-TiO2)@C3N4-5 catalyst are 37.4 and 21.7 μmol g−1 h−1, respectively. The selectivity for CO2 reduction is higher than 99%, and the selectivity of CH4 product increases from 1.4% to 63.3%. The innovation of Z-scheme-type photocatalysts is expected to provide new inspiration for artificial simulation photosynthesis.
