NiCo-carbonate layered double hydroxides of diverse morphologies, such as nanorod, microcube, microplate and urchin-like, are synthesized by a single-step synthesis their electrochemical energy storage performance is evaluated.
Herein, a solution-based route is presented to fabricate Cu(OH)2/Co(OH)2 heterostructures directly on copper foil (CF) as potential electrode material for supercapacitor application. First CF etched form uniform Cu(OH)2 nanobelt-like structures its surface. Using the same substrate, Co(OH)2 nanosheets are electrochemically grown nanobelts heterostructure at room temperature. The electrodeposition duration determines density of substrate. With an 900 s, maximum areal capacitance achieved and...
To overcome the increasing energy demand worldwide, semiconductor-based photocatalytic H2 production by water splitting has gained much recognition as an alternative approach. However, main drawbacks are lower visible light absorption and rapid recombination of photogenerated electrons–hole pairs in photocatalysts. This work reports synthesis CdS/ZnS heterostructures with varied compositions each component via a single-step solvothermal method calcination under vacuum. An optimized...

A microwave-assisted hydrothermal method is demonstrated to synthesize Co<sub>3</sub>O<sub>4</sub> nanostructures as the positive electrode and a graphene hydrogel negative for supercapacitor.
The production of hydrogen via electrocatalytic reduction water using metal-free nanomaterials as the catalyst is a promising and ultimate green approach. Graphitic carbon nitride, covalent organic frameworks, triazine frameworks (CTFs) are some nanostructured materials that investigated for this purpose. Currently, these still lack efficiency to compete with other techniques (electrolysis). This because reaction mechanism active sites are, in many cases, poorly understood. In work, we...
Ammonia is the second-most produced chemical throughout world to maintain global food supply and other stocks.
The morphology of nanomaterials plays an important role in catalysis and other applications. Herein, we demonstrate that not only the but also crystal phase nanomaterial significant roles. A single-step synthesis α- β-Co(OH)2 with a unique is demonstrated, their oxygen evolution reaction (OER) activity presented. Nanocone-like α-Co(OH)2 hexagonal plate-like nanostructures are obtained by facile reflux method using structure-regulating reagent to control morphology. exhibits small...
