Various raw materials from natural or synthetic sources are used in electrospinning as a polymer or an additive. Of these raw materials, biomass or organic waste-derived materials have become an area of interest due to their availability, cost-performance level, unique functionalities, and rising demand for sustainable, eco-derived, and friendly materials. Either plant-based or animal-based, a great number of materials can be used in electrospinning such as starch, lignocellulose, alginate, keratin, chitosan, etc. Each material has its typical electrospinning conditions some of which bring considerable challenges for successful nanofiber production. To overcome these challenges and find the optimum material type and process conditions, we introduced a novel Picture Fuzzy Multiple Attribute Decision Making (MCDM)-based sorting tool, namely PiF-ARASsort-lp, to classify material alternatives into three categories based on different attributes. The recommended model not only provides cost efficiency but also offers an opportunity to evaluate different materials for many aspects in a quick manner based on expert opinions. To facilitate the opinion-gathering process, a new data collection scheme is applied.

The electrochemical reduction of CO₂ (CO₂RR) offers a promising strategy to convert CO₂ into valuable products such as ethylene (C₂H₄), methane (CH₄), carbon monoxide (CO), methanol (CH₃OH), and ethanol (C₂H₆O). In this study, we report the integration of Cu-based metal-organic framework (MOF) electrocatalysts into gas diffusion layers (GDLs) to enhance CO₂RR performance. Electrocatalysts, specifically Cu/ZnO-UiO66 and Cu/ZnO-MDC, were deposited onto GDLs using an air-spraying technique, ensuring a homogeneous distribution of active metals across the substrate. Comprehensive characterisation of the modified GDLs was performed using field-emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (FESEM-EDX), X-ray diffraction (XRD), and tensiometer to assess surface morphology, textural properties, and phase composition, respectively. The deposition process resulted in a notable increase in hydrophilicity compared to pristine GDLs, as indicated by reduced contact angles. CO₂RR experiments conducted in a liquid flow system demonstrated that the Cu/ZnO-UiO66-based GDL achieved FEs of 40 % for CO production, 6 % for CH₄, and 3 % for C₂H₄, at a cathodic potential of −1.0 V vs RHE. In contrast, the Cu/ZnO-MDC-based GDL delivered FEs of 17 % for CO and 10 % C₂H₄, as well as 2 % for CH₄, under similar conditions.

A case study is examined in which hydrogen is transported from North Africa to Italy.
