Abstract:Electrospinning is one of the most successful and efficient techniques for the fabrication of one-dimensional nanofibrous materials as they have widely been utilized in multiple application fields due to their intrinsic properties like high porosity, large surface area, good connectivity, wettability, and ease of fabrication from various materials. Together with current trends on energy conservation and environment remediation, a number of researchers have focused on the applications of nanofibers and their co… Show more
“…Wind Rose (July–September): During the months of July and September, the wind is stronger in the west direction, with an average speed of 26.103 km/h. Wind speeds vary from 3.9 to 5.8 knots, or 6.1 to 9.1 km/h, on around 120 days out of the year, or 33% of the time [ 4 , 14 ]. Fig.…”

“…3). Renewable and abundant biomass-derived polymers, such as cellulose, lignin, alginate, chitosan, and pectin, are considered ideal candidates for the fabrication of green composites with unique properties of biodegradability, low weight, high surface area, tunable morphologies, flexibility, and strength (Ji et al 2020;Baghali et al 2021). Furthermore, such nature biopolymers provide other outstanding features such as excellent transparency, which allows the sunlight to transmit thoroughly and maximizing the performance of the photocatalyst.…”
The last decade has been witnessing overwhelming efforts to achieve social sustainability from mitigating the health and environmental effects to innovative new strategies for sustainable energy production. Those efforts have been devoted to exploiting sustainable materials for handling energy shortage and environmental deterioration to fulfill the Sustainable Development Goals (SDGs). In this article, we engage in those efforts and shed new light on sustainable models applicable to water, air, and solid management from the practical standpoint of SDGs. The first sustainable model is a combination between renewable resources and sustainable materials for the fabrication of biomass/photocatalysts hybrid composites. The green hybrid photocatalysts can be synthesized by electrospinning or 3D techniques. These geometric bio-hybrid photocatalysts are the backbone of the next photocatalytic house model. These houses can significantly participate in the mitigation of climate change via CO 2 capture and conversion to renewable energy and fuels. Furthermore, it anticipates that these photocatalytic houses are capable of participating in the alleviation of acid rain through converting toxic gasses such as nitrogen oxide (NO x ) and sulfur oxide (SO x ) into sustainable products. On the other hand, some suggestions have been raised to face and control microplastic pollution and one of these suggestions is introducing artificial intelligence such as tracer-based sorting as a sustainable strategy solution to enhance the plastic circular economy. The last model relies on optimizing the utilization of Jatropha in the landfill post-closure area toward integrated solid waste management and alternative biofuel production. These models will pave new ways of realizing sustainability.
“…However, the application of aerogels and electrospun materials to the capture of CO 2 or as catalysts for the conversion of CO 2 into added‐value products is a relatively new field of research that can contribute to the development of clean energy technologies with zero CO 2 emissions, [2d,4] e. g. through the power‐to‐gas (P 2 G) technology, which explains the renewed interest in the hydrogenation of CO 2 aiming the production of methane [5] . The P 2 G technology is a concept that converts electrical into chemical energy using CO 2 and H 2 O.…”
Nanostructured Cobalt-Actinide (An=Th, U) bimetallic oxides were for the first time prepared by the epoxide addition method and electrospinning technique aiming the synthesis of aerogels and nanofibers, respectively. Tested as catalysts for the methanation of CO 2 and regardless of the actinide element, the yield and selectivity towards CH 4 are high (> 40 and 95 %, respectively), which was explained by their physicochemical properties such as reducibility and basicity and the existence of a synergic effect between cobalt and actinide species. The aerogels present the best catalytic behavior, namely those with thorium and the catalytic activity increases with the Co/An molar ratio. Both aerogels and nanofibers also present a high resistance to deactivation for at least 75 h in the gaseous stream, which is an advantage for any catalytic application. Moreover, at 300 °C they are 2 to 4 times more active than two reference catalysts (5 wt % Rh/Al 2 O 3 and NiO/Al 2 O 3 ) tested in the same conditions, which to our best knowledge is a significant result.
