Facile and controllable synthesis of sea urchin-like CuCoO on Ni foam for high-performance supercapacitors.

CuCoO is considered to be an attractive electrode material for supercapacitors due to its low toxicity, high theoretical capacity and low cost. However, the low specific capacity, poor cycling performance and low intrinsic conductivity limit the further application of CuCoO. In this research, CuCoO arrays with different morphologies (rods, sea urchin-like and flakes) were synthesized on the surface of nickel foam (NF) a solvothermal method and calcination.

Facile synthesis of ATTM@ZIF-8 modified pullulan hydrogels for enhanced adsorption of Congo red and malachite green.

Efficient capture of dyes from wastewater is of great importance for environmental remediation. Yet constructing adsorbents with satisfactory adsorption efficiency and low cost remains a major challenge. This work reports a simple and scalable method for the fabrication of functionalized porous pullulan hydrogel adsorbent decorated with ATTM@ZIF-8 for the adsorption of congo red (CR) and malachite green (MG).

High-capacity adsorption of organic dyes using separable pullulan gel encapsulated with PDA-modified ZIF-8.

In this investigation, a hydrogel adsorbent featuring remarkable efficiency in dye adsorption was successfully synthesized by the integration of natural polysaccharide (pullulan) and nanoparticles (ZIF-8@PDA). The prepared natural polysaccharide nanocomposite hydrogels not only exhibit superior mechanical strength and biocompatibility, but also demonstrate adeptness in the removal of dye pollutants. The dye removal capacities were 615.
