When designing a device for energy conversion, development of a highly active catalyst for OER (oxygen evolution reaction) reaction in alkaline medium is of utmost importance. For energy conversion, herein, we developed copper cobalt sulfide on carbon cloth (CC) using a simple and facile hydrothermal method. A vertically grown 2D sheet-like structure of coppercobalt sulfide is observed using L-cysteine as a sulfur source. An optimized ratio of copper(II) and cobalt(III) and the best sulfur source are found to boost the electrocatalytic activity of mixed metal thiospinel for OER. Several characterization techniques (XRD, Raman, FESEM, TEM, XPS, and ICP-AES) were used to confirm phase purity, morphology, and composition of copper cobalt sulfides. We have established that 2D nanosheets of CuCo 3 S z /CC exhibited superior electrocatalytic performance over bare RuO 2 in 1.0 M KOH solution. It is observed that CuCo 3 S z /CC need only 105 mV overpotential to generate 5 mA/ cm 2 current density. CuCo 3 S z /CC is very stable and able to produce unaltered current density under an applied potential of 1.615 V vs. RHE for 48 h. Electrochemically active surface area calculation is performed for all catalysts to confirm higher electrocatalytic activity. The catalyst, CuCo 3 S z /CC is used in a broad pH region using 0.5 M KOH, saline water, and 0.5 M Na 2 SO 4 electrolyte solution to widen the applicability of water splitting. This work shows an avenue to develop active and durable electrocatalyst for OER without using any noble metal electrocatalyst.[a] C.

In this paper, we prepared CuCo 2 S 4 /MWCNTs as a heterogeneous iron-free bimetal catalyst for the degradation of methylene blue (MB) dye by uniformly synthesizing CuCo 2 S 4 nanoparticles on the surfaces of multiwalled carbon nanotubes (MWCNTs). The homogeneous nanostructure, tuned by MWCNTs, and the efficient electron transfer from CuCo 2 S 4 to MWCNTs resulted in a quite decent catalytic activity, which was superior to that of pristine CuCo 2 S 4 and monometal sulfides. Moreover, CuCo 2 S 4 /MWCNTs maintained a good catalytic performance over a broad pH range of 3 to 12, and exhibited better MB degradation rates under alkaline conditions. Meanwhile, the catalyst was reusable for up to three cycles due to the strong interaction between the nanoparticles and MWCNTs. The results demonstrate that CuCo 2 S 4 /MWCNTs is an improved Fenton catalyst and a promising candidate to substitute iron-based catalysts for the treatment of wastewater containing dyes.

Mixed metal sulfides (MMSs) have attracted increased attention as promising electrode materials for electrochemical energy storage and conversion systems including lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), hybrid supercapacitors (HSCs), metal–air batteries (MABs), and water splitting. Compared with monometal sulfides, MMSs exhibit greatly enhanced electrochemical performance, which is largely originated from their higher electronic conductivity and richer redox reactions. In this review, recent progresses in the rational design and synthesis of diverse MMS‐based micro/nanostructures with controlled morphologies, sizes, and compositions for LIBs, SIBs, HSCs, MABs, and water splitting are summarized. In particular, nanostructuring, synthesis of nanocomposites with carbonaceous materials and fabrication of 3D MMS‐based electrodes are demonstrated to be three effective approaches for improving the electrochemical performance of MMS‐based electrode materials. Furthermore, some potential challenges as well as prospects are discussed to further advance the development of MMS‐based electrode materials for next‐generation electrochemical energy storage and conversion systems.
