Polydopamine assisted transformation of ZnO from nanospheres to nanosheets grown in nanoporous BiVO4 films for the improved photocatalytic performance

This work demonstrates the fabrication of nanoporous BiVO4/ZnO nanosheets heterostructures grown on stainless steel mesh. The ZnO nanospheres were used as precursors for ZnO nanosheets, and the number of ZnO...

Photopolymerized superhydrophobic hybrid coating enabled by dual-purpose tetrapodal ZnO for liquid/liquid separation

The development of low-cost and scalable superhydrophobic coating methods demands viable approaches for energy-efficient separation of immiscible liquid/liquid mixtures. A scalable photoinitiated method is developed to functionalize stainless-steel mesh with...

The Electrochemical Performance of δ-MnO2 Cathode Material for Aqueous Zinc-Ion Batteries: The Role of Current Collector

Electrochemical properties of δ-MnO2-based cathode materials were studied in dependence on current collector used for electrode casting (stainless steel mesh, carbon paper and titanium foil) by galvanostatic charge/discharge measurements and cyclic voltammetry. It was shown that δ-MnO2-based electrodes cast on carbon paper demonstrate the most stable electrochemical performance in comparison with two other current collectors. This can be explained by corrosion of steel and passivation of titanium in mild aqueous electrolytes. Detailed study of carbon paper as current collector shows that pressing of electrodes leads to decreasing the porosity and fast capacity fading.
