Nanomaterials have been developed utilizing organosulphur compounds, and the applications of such nanomaterials have been explored in catalysis and electrocatalysis.

For the first time, palladium telluride nanoparticles have been explored for Oxygen evolution reaction (OER). Pd ₉ Te ₄ nanospheres have been synthesized by using a simple, hassle‐free, and one‐pot method, that is single source precursor route. Palladium(II) complex of a bidentate Schiff base having (Te,N) donor sites was thermolyzed at 220 °C under inert atmosphere to obtain Pd ₉ Te ₄ which showed excellent potential for OER. It needs an overpotential of only 310 mV to drive the anodic current density of 10 mAcm ⁻² and it has shown stability for more than 17 h.

During the last two decades, organosulfur compounds have been used in the field of transition metal catalysis. Some of such compounds are known for their ability to withstand their exposure to air and moisture. These compounds are very important ligands. They may be obtained using simple and smooth modular synthetic protocols which include nucleophilic substitution reactions. The development of click chemistry represents a new era of innovation. It is a lighthouse of reliable and efficient reactions. In recent past, click chemistry has also been applied for the synthesis of such organosulfur ligands specifically suited for the dynamic field of transition metal catalysis. In order to synthesize novel compounds containing sulfur and triazole ring, click chemistry is an advantageous methodology over other approaches. This article covers the general features and uses of this methodology for the development of catalytically active organosulfur compounds. The significant advances in the design of transition metal catalytic systems utilizing such ligands, their use in the catalysis of many chemical transformations are also covered in this article. Effort has also been made to present a comparative overview of the performances of such catalysts vis‐à‐vis the catalysts designed commonly used ligands. Catalytic performances have been discussed thoroughly in order to identify the impact of ligand architecture on efficacy of the catalyst. Effect of reaction conditions (such as time, temperature etc.) and mechanistic aspects have also been rationalized.
