“…Transition-metal-based nanostructured complexes, constituting a bizarrely broad class of compounds, exhibit diverse properties and functionalities due to their rich structure, outstanding stability, and environment-friendliness. For instance, transition-metal-based nanomaterials can exhibit bacterial toxicity through various mechanisms such as producing reactive oxygen species (ROS), including H 2 O 2 , hydroxyl radical (·OH), singlet oxygen ( 1 O 2 ), and ion leaching. , The exceptionally wide variety of performances stem mainly from the unique nature of outer shell d electrons in pristine oxides, leading to implications in various fields such as green energy, magnetism, and gas sensors. − Although transition metal (M) oxides display intriguing responses in various fields, their poor electronic conductivity has posed a major hurdle for a range of applications. One way to circumvent this issue without altering their performance is to engineer metal, tellurium (Te), and oxygen-based compounds, as Te exhibits a much higher electronic conductivity.…”

Materials that lead to devices with tunable responses to the morphology are a potential opportunity. Tellurium, a growing material class possessing higher electronic conductivity, has recently been seen to exhibit the same in transition-metal-based complexes when combined toward wider energy applications. However, it has rarely been engineered and implemented for morphology-dependent low-dimensional (LD) structures for catalytic reactions. Herein, for the first time, we provide a novel approach for designing dimension variable nano nickel tellurate (NTO), such as nanorods (NRs), through pH assisted anisotropic transformation from the zero-dimensional amorphous counterpart. The resulting NRs have an average width of 5–30 nm and lengths in micrometers. Mechanistic studies show that the morphology of the final product is determined by the pH value used. In line with structural phase analysis, average core-level spectroscopic and local spectro-microscopic determinations confirm the formation of Ni2+- and Te4+/Te6+-based NTO NRs via electronic structure investigation and covalency. Our study not only provides a fresh approach to achieve varied NTO NRs but also offers insights into the growth reaction mechanisms of anisotropic transformation. The proposed facile design scheme can be optimized to synthesize any nanotellurates with morphological purity to promote the catalytic reactions through low-dimensional activity. As an example, these samples were tested for the oxygen evolution reaction.
