Polyoxometalate-HKUST-1 composite derived nanostructured Na-Cu-MoC catalyst for efficient reverse water gas shift reaction.

Transforming CO to CO reverse water-gas shift (RWGS) reaction is widely regarded as a promising technique for improving the efficiency and economics of CO utilization processes. Moreover, it is also considered as a pathway towards e-fuels. Cu-oxide catalysts are widely explored for low-temperature RWGS reactions; nevertheless, they tend to deactivate significantly under applied reaction conditions due to the agglomeration of copper particles at elevated temperatures.

High-performance hybrid supercapacitor-immobilized Wells-Dawson polyoxometalates on activated carbon electrodes.

The nanofabrication of electroactive hybrid materials for next-generation energy storage devices is becoming increasingly significant as supercapacitor (SC) technology develops rapidly. The present study utilizes activated carbon (AC) templates reinforced with Wells-Dawson polyoxotungstates (POMs) to produce nanohybrid electrodes for high-performance supercapacitors. This study analyzes Wells-Dawson polyoxotungstates (PW) for the first time integrated with AC, and its structural and electrochemical performances are discussed.

Waste dry cell derived photo-reduced graphene oxide and polyoxometalate composite for solid-state supercapacitor applications.

In the modern era, realizing highly efficient supercapacitors (SCs) derived through green routes is paramount to reducing environmental impact. This study demonstrates ways to recycle and reuse used waste dry cell anodes to synthesize nanohybrid electrodes for SCs. Instead of contributing to landfill and the emission of toxic gas to the environment, dry cells are collected and converted into a resource for improved SC cells.

Assembly of a coordination polymer with sulphate-capped pentamolybdate units and copper: synthesis, structure, magnetic and catalytic studies.

A new coordination polymer based on the sulphate-capped pentamolybdate unit has been synthesized from the reaction of {MoSBr} with copper(II) bromide and pyridine, in DMF. The as-synthesized compound, formulated as [Cu(CHN)][{MoVI5O(SO)}{Cu(CHN)(DMF)(HO)}][MoVI5O(SO)]·2DMF (1), crystallizes in the monoclinic space group of 2/. This compound has a one-dimensional double-chain coordination polymeric structure, composed of the pentameric {MoVI5O(SO)} and the {Cu(CHN)} units, and has been characterized in the solid-state with single-crystal and powder X-ray diffraction, infrared and optical spectroscopy, as well as thermal and magnetic studies.
