Incorporating Indium Oxide into Microplasma Reactor for CO Conversion to Methanol.

The clean conversion of CO is a strategic issue for addressing global climate change and advancing energy transformation. While the current clean CO conversion is limited to the H pyrolysis process, using HO as a proton source is more promising and sustainable. A microplasma discharge method is developed, driven by electricity, and utilized for CO conversion with HO.

Ultrasonic-Induced Surface Disordering Promotes Photocatalytic Hydrogen Evolution of TiO.

Surface disordering has been considered an effective strategy for tailoring the charge separation and surface chemistry of semiconductor photocatalysts. A simple but reliable method to create surface disordering is, therefore, urgently needed for the development of high-performance semiconductor photocatalysts and their practical applications. Herein, we report that the ultrasonic processing, which is commonly employed in the dispersion of photocatalysts, can induce the surface disordering of TiO and significantly promote its performance for photocatalytic hydrogen evolution.

Sustainable HO production via solution plasma catalysis.

Clean production of hydrogen peroxide (HO) with water, oxygen, and renewable energy is considered an important green synthesis route, offering a valuable substitute for the traditional anthraquinone method. Currently, renewable energy-driven production of HO mostly relies on soluble additives, such as electrolytes and sacrificial agents, inevitably compromising the purity and sustainability of HO. Herein, we develop a solution plasma catalysis technique that eliminates the need for soluble additives, enabling eco-friendly production of concentrated HO directly from water and O.

Activation of 2D titanate nanosheet photocatalysts by nitrogen doping and solution plasma processing.

Novel two-dimensional (2D) oxides are of great interest for photocatalysis because of their superlative physical features, namely, large surface areas, short charge diffusion pathways, high crystallinity and easy surface modification. However, most 2D oxides suffer from weak visible light absorption and severe photogenerated carrier recombination. Nitrogen doping can successfully narrow the bandgap of 2D oxides but can hardly improve the charge separation.

Double knockout of FFAR4 and FGF21 aggravates metabolic disorders in mice.

Several investigations have examined the involvement of free fatty acid receptor 4 (FFAR4) in metabolic disorders, but its action remains controversial. To investigate whether endogenous fibroblast growth factor 21 (FGF21)-mediated signaling controls the metabolic status in FFAR4-deficient mice, we generated FFAR4/FGF21 double knockout (DKO) mice. We also evaluated the role of FGF21 on glucose and lipid metabolism in FFAR4 KO mice fed a high-fat diet.

Synergy of Adsorption and Photocatalytic Reduction for Efficient Removal of Cr(VI) with Polyvinylidene Fluoride@Polyvinyl Alcohol-FeCO/BiWO.

Although the photocatalytic reduction of Cr(VI) to Cr(III) by traditional powder photocatalysts is a promising method, the difficulty and poor recovery of photocatalysts from water hinder their wide practical applications. Herein, we present that FeCO/BiWO (FeCO/BWO) composites were tightly bonded to modified polyvinylidene fluoride (PVDF) membranes by chemical grafting with the aid of polyvinyl alcohol (PVA) to form photocatalytic composite membranes (PVDF@PVA-FeCO/BWO). The contact angle of PVDF@PVA-FeCO/BWO (0.

Ethanol Solution Plasma Loads Carbon Dots onto 2D HNbO for Enhanced Photocatalysis.

Layered metal oxoacids hold potential as photocatalysts due to their facile exfoliation to two-dimensional (2D) nanosheets with a large surface area and a short migration distance for photoexcited charge carriers. However, the utilization of electrons in photocatalytic processes is restricted by the competitive trapping of electrons by metal ions. In this work, we attempt to improve the utilization of photogenerated electrons over exfoliated HNbO nanosheets by solution plasma activation.

Photocatalytic reduction of Cr(VI) by BiWO complexed with polydopamine: Contribution of the ligand-to-metal charge transfer path.

Photocatalytic reduction of Cr(VI) in water environments attracts more attention; however, the mechanisms involved in this process have not been clearly elucidated yet. In this study, the photocatalytic reduction of Cr(VI) by polydopamine modified BiWO (PDA/BWO) under visible light was conducted. Kinetics results show that PDA apparently accelerates the reduction of Cr(VI).

Influence of the pre-elution of solute in initial mobile phase on retention time and peak compression under linear gradient elution.

Under gradient elution the solute will firstly migrate in initial mobile phase due to dwelling time (t) of the system. The pre-elution of solute in initial mobile phase can be accounted for by a dimensionless value of t/(tk), where t and k denote dead time and retention factor in initial mobile phase, respectively. The influence of t/(tk) on retention time (t) and peak compression factor (G) are discussed under linear gradient elution.
