Abstract

Potassium ions batteries (PIBs) have been regarded as a promising choice for electrical energy storage technology due to the wide distribution of potassium resources. However, developing low-cost and robust earth-rich anode materials is still a major challenge for the practical and scalable usage of PIBs. Herein, for the first time, we developed nitrogen doped carbon coating CoS2/CuCo2S4 heterostructure (CoS2/CuCo2S4@NCs) hollow spheres and evaluated as anode for PIBs. The CoS2 and CuCo2S4 heterostructure interface could generate a built-in electric field, which can fasten electrons transportation. The nanostructures could shorten the diffusion length of K+ and provide large surface area to contact with electrolytes. Furthermore, the inner hollow sphere morphology along with the carbon layer could accommodate the volume expansion during cycling. What’s more, the N-doped carbon could increase the conductivity of the anodes. Benefitting from the above features, the CoS2/CuCo2S4@NCs displays an outstanding rate capability (309 mAh g−1 at 500 mA g−1 after 250 cycles) and a long-term cycling life (112 mAh g−1 at 1000 mA g−1 after 1000 cycles) in ether-based electrolyte. Conversion reaction mechanism in CoS2/CuCo2S4@NCs anode is also revealed through ex situ XRD characterizations. This work provides a practical direction for investigating metal sulfides as anode for PIBs.

Abstract

The recycling technology of photocatalyst powdery has hardly been mature in the photocatalytic oxidation so far. In this work, the hollow TiO2 microspheres with an appropriate thickness are confined in carbon microspheres (CMSs) to form hollow TiO2@CMSs, which are physically integrated with carbon-fiber textile by van der Waals (vdW) interactions to generate separable and recyclable hollow TiO2@CMSs/carbon-fiber vdW heterostructures. Such separable and recyclable heterostructures show remarkable oxidation of 2,4-dinitrophenol. From our detailed characterization and density functional theory (DFT) calculations, we found that carbon fiber can trap electrons exerted from the excitation of hollow TiO2@CMSs and creates holes in hollow TiO2 microspheres, which endow the carbon fiber with photoelectric activity through coherent charge injection. This study indicates that our general strategy for the fabrication of hollow TiO2@CMSs/carbon-fiber vdW heterostructures can be used as separable and recyclable photocatalyst and photoelectrocatalyst with potential industrial applications in environment-related fields.

Abstract

Spent selective catalytic reduction (SCR) catalysts are defined as hazardous wastes because of the toxicity of V2O5 to the ecological environment. Recycling of V2O5 and TiO2 from the spent SCR catalysts has strikingly social and environmental benefits as well as economic values. In this work, a “NaOH ​+ ​Na2CO3” system was employed to recycle 99.2% of anatase/rutile TiO2 nanospheres with a nanospherical morphology from the spent SCR catalysts by a simple sintering-leaching process. The observed photocatalytic performance of anatase/rutile TiO2 nanospheres was higher than that of the other TiO2 recovered from the spent SCR catalysts, commercial TiO2, and chemosynthetic TiO2, which can be ascribed to the enhanced separation of photo-excited electron/hole in a direct Z-scheme of anatase/rutile TiO2 homostructures. Additionally, high-purity V2O5 microrods with high H2S removal performance were efficiently prepared by a hydrothermal method in the leaching solution, which is superior to the traditional method including NH4VO3 precipitation and solvent extraction as the present method can recycle vanadate from low-grade filtrate with a 99.6% of recovery rate. This study develops an alternative method for controlling pollution of vanadate to soil and water and recycling of valuable metals.

Abstract

Due to its appropriate bandgap (∼2.4 eV) and efficient light absorption, bismuth vanadate (BiVO4) shows promising photocatalysis activity. However, the charge carrier recombination and poor electron transmission often induce poor photocatalytic performance. Herein, we report a new method to in-situ synthesize non-noble metal Bi decorated mulberry-like BiVO4 by a two-step calcination process. Comprehensive characterizations reveal that non-noble metal Bi nanoparticles grown in-situ on BiVO4 result in the red-shift of the absorbance edge, greatly extending the light absorption from the ultraviolet into the near-infrared region. The surface plasmon resonance excitation of Bi nanoparticles and synergetic effects between Bi and BiVO4 effectively improve the photocatalytic efficiency and promote the separation of photoinduced electron-hole pairs in mulberry-like BiVO4. Density functional theory (DFT) calculation results further verify that the electrons are transferred from Bi to BiVO4 and the formation of OH radical in Bi/BiVO4 is attributed to the lower simulated free energy, which supports our experimental outcomes. This work provides a novel strategy to enhance light absorption and promote efficient solar utilization of photocatalysts for practical applications.

Abstract

The van der Waals (vdW) integration enables to create heterostructures with intimate contact and bring new opportunities. However, it is not confined to layered materials but can also be generally extended to 3D materials. Multidimensional Bi2O3/BiVO4@graphene oxide (GO) van der Waals heterostructures are synthesized by one-pot wet chemistry method. Bi2O3/BiVO4 composite nanoparticles are self-assembled with GO framework by vdW interaction to form vdW heterostructures, in which GO framework allows short electron transport distance and rapid charge transfer and provides massive reactive sites. Such self-assembled heterostructures show a superior high photoactivity towards oxygen evolution with an enhanced oxygen generation rate of 1828 µmol h−1 g−1, nearly 3 times than that of pure BiVO4, attributed to the accelerated charge separation and transfer processes of Bi2O3/BiVO4@GO vdW heterostructures. This study indicates that our strategy provides a new avenue towards fabricating multi-dimensional vdW heterostructures and inspiring more innovative insights in oxygen evolution field.
