At present, the world is at the peak of production of traditional fossil fuels. Much of the resources that humanity has been consuming (oil, coal, and natural gas) are coming to an end. The human being faces a future that must necessarily go through a paradigm shift, which includes a progressive movement towards increasingly less polluting and energetically viable resources. In this sense, nanotechnology has a transcendental role in this change. For decades, new materials capable of being used in energy processes have been synthesized, which undoubtedly will be the cornerstone of the future development of the planet. In this review, we report on the current progress in the synthesis and use of one-dimensional (1D) nanostructured materials (specifically nanowires, nanofibers, nanotubes, and nanorods), with compositions based on oxides, nitrides, or metals, for applications related to energy. Due to its extraordinary surface–volume relationship, tunable thermal and transport properties, and its high surface area, these 1D nanostructures have become fundamental elements for the development of energy processes. The most relevant 1D nanomaterials, their different synthesis procedures, and useful methods for assembling 1D nanostructures in functional devices will be presented. Applications in relevant topics such as optoelectronic and photochemical devices, hydrogen production, or energy storage, among others, will be discussed. The present review concludes with a forecast on the directions towards which future research could be directed on this class of nanostructured materials.

<ul>Landfill leachate, a highly contaminated percolating effluent can cause a considerable threat to human as well as environmental health. We developed a novel nano composite using the polymer encapsulated magnetic geopolymer for efficient removal of multi contaminants (As, Zn, Fe, Co, Cu, Ni, Pb, F, NO 3 - , and PO 4 3- ) present in the landfill leachate and groundwater of the Pirana solid waste dumping site, Ahmedabad, Gujarat. A series of batch and column sorption experiments were carried out to find the best-operating conditions for optimum removal efficiency. Results revealed that in the range of 50-60% of multi-contaminant removal is possible using the newly developed adsorbent which has high surface area as well as mixed functional groups for the removal of both cationic (Zn, Fe, Co, Cu, Ni, and Pb) and anionic (F, NO 3 - , and PO 4 3- ) contaminants present in the leachate. Batch study shows that both physical and chemical sorption are equally operational and multilayer removal following the Freundlich isotherms predominantly. The batch test mimics the equilibrium condition only. The study recommends column study under different follow conditions using leachate and groundwater, followed by a regeneration study for its reusability and development of the field implementation schemes. The future research is required to address the decontamination of emerging contaminants like pharmaceuticals, pesticides and fertilizers, industrial additives and antibacterial agents.</ul>

There has been an increasing demand for the development of sensor devices with improved characteristics such as sensitivity, low cost, faster response, reliability, rapider recovery, reduced size, in situ analysis, and simple operation. Nanostructured materials have shown great potential in improving these properties for chemical and biological sensors. There are different nanostructured materials which have been used in manufacturing nanosensors which include nanoscale wires (capability of high detection sensitivity), carbon nanotubes (very high surface area and high electron conductivity), thin films, metal and metal oxide nanoparticles, polymer, and biomaterials. This review provides different methods which have been used in the synthesis and fabrication of these nanostructured materials followed by an extensive review of the recent developments of metal, metal oxides, carbon nanotubes, and polymer nanostructured materials in sensor applications.

Abstract To address the growing energy demands of sustainable development, it is crucial to develop new materials that can improve the efficiency of energy storage systems. Hierarchically structured porous materials have shown their great potential for energy storage applications owing to their large accessible space, high surface area, low density, excellent accommodation capability with volume and thermal variation, variable chemical compositions and well controlled and interconnected hierarchical porosity at different length scales. Porous hierarchy benefits electron and ion transport, and mass diffusion and exchange. The electrochemical behavior of hierarchically structured porous materials varies with different pore parameters. Understanding their relationship can lead to the defined and accurate design of highly efficient hierarchically structured porous materials to enhance further their energy storage performance. In this review, we take the characteristic parameters of the hierarchical pores as the survey object to summarize the recent progress on hierarchically structured porous materials for energy storage. This is the first of this kind exclusively to survey the performance of hierarchically structured porous materials from different porous characteristics. For those who are not familiar with hierarchically structured porous materials, a series of very significant synthesis strategies of hierarchically structured porous materials are firstly and briefly reviewed. This will be beneficial for those who want to quickly obtain useful reference information about the synthesis strategies of new hierarchically structured porous materials to improve their performance in energy storage. The effect of different organizational, structural and geometric parameters of porous hierarchy on their electrochemical behavior is then deeply discussed. We outline the existing problems and development challenges of hierarchically structured porous materials that need to be addressed in renewable energy applications. We hope that this review can stimulate strong intuition into the design and application of new hierarchically structured porous materials in energy storage and other fields.
