“…Although this multilayer material is seemingly very applicable and recyclable, it suffers from a very complex and expensive preparation method . Beyene et al prepared a triple-layered cylindrical ZnO@SiO 2 @Ag CS nanostructure via a multistep synthesis strategy. This material with a band gap of 3.31 eV was deployed to degrade MB under UV–vis-light irradiation, wherein its enhanced photoactivity, stability, and optical absorbance mainly related to the plasmonic Ag shell .…”

Hybrid nanostructures and nanoarchitectures possess unique physicochemical properties such as high activity/functionality, enhanced physicochemical stability, and improved biocompatibility, which renders them suitable for various biomedical, pharmaceutical, environmental, and catalytic applications. In this context, core–shell nanophotocatalysts have shown superior activity compared to their counterparts, namely, their individual pristine semiconductors and composite materials components. Thus, the development of various innovative core–shell nanostructures as photocatalysts is of practical relevance in view of their unique properties with salient advantageous features applicable to, among others, the degradation of organic pollutants, energy storage, and H2 generation. Assorted techniques are deployed to synthesize core–shell nanostructures, including chemical vapor deposition, sol–gel, hydrothermal, spin-coating deposition, solvothermal, combustion waves, microwave (MW)- and ultrasonic-assisted, electrodeposition, laser ablation, and biological approaches. Because core–shell nanostructures provide an immense opportunity to have the most efficient photocatalysts with high stability and reproducibility; herein, the recent advances in this domain are discussed, comprising the most important fabrication techniques and diverse appliances including important challenges and unrealized opportunities.

Summary Development of high‐authority and rich‐in‐crust bifunctional electrocatalysts for overall water splitting has a great significance of clean energy storage and conversion with both of the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). In this work, cobalt‐iron complex sulfides with the same metal molar ratio firmly grown on the surface of nickel foam modified by reduced graphene oxide (Co0.50Fe0.50S‐rGO@NF) was prepared and acted as a superior electrocatalyst for electrolyzing water. The same mole ratio of bimetallic‐cation doping can induce strong electron‐interaction between the complex sulfides and the surface of nickel foam carrier modified by reduced graphene oxide, which reduces the electronic adsorption energy required for HER and OER, as well as improves the electrocatalytic active area exposure. As a result, the optimal electrocatalyst of Co0.50Fe0.50S‐rGO@NF behaves excellent electrocatalytic performance with the overpotential of 189 mV @ η20 mA·cm−2 in 1.0 M KOH solution for OER and the overpotential of 155 mV @ η10 mA·cm−2 in 0.5 M H2SO4 solution for HER, respectively. A self‐built conventional two‐electrode electrolytic cell by using Co0.50Fe0.50S‐rGO@NF as the anode and cathode presents lower voltages of 1.39 and 1.66 V to deliver the current density of 10 mA·cm−2 in 1.0 M KOH and 1.0 M PBS electrolytes, respectively. This study underlines the synergism of the bimetallic‐cation doping complex sulfides loaded on nickel foam modified by rGO for boosting the electrocatalytic activity of overall water splitting.
