- Deliverable 2.3: research report on society and naturePublication . Alves, Fátima; Vidal, Diogo Guedes; Valentim, Cristina Sá; Guazzini, Andrea; Duradoni, Mirko; Costa, Paulo Manuel; Novelli, Luca; Puttini, SpartacoIn this deliverable “Research Report on Society and Nature” (D2.3) we intend to contribute to three major aspects of the Phoenix project, namely, the understanding of society-nature relations and their construction, the sociocultural influence on the implementation of the European Green Deal, and the methodological approaches to foster green transition in each pilot territory. The deliverable firstly aims to contribute to (1) a broader understanding of how societies and individuals in each pilot territory make sense and produce meanings about their relation with nature and the environment from different socio-cultural backgrounds, as sociocultural constructions; (2) secondly, to understand to what extent different sociocultural constructions of Nature and Environment can condition the implementation of European Green Deal measures and contribute to the ecological transition; and thirdly, (3) based on the social construction of nature and the environment in each pilot territory, provide considerations for the identification of the best methodological approach for deliberative and participatory processes ). This report emphasizes that the successful involvement of people in the ecological transition requires mechanisms of participation that are grounded in fair, inclusive, and plural processes. A transformative policy for ecological transition must deeply understand the biophysical, socio-economic, and cultural characteristics of the territories, requiring transformative processes at both individual and structural levels.
- Sisal-derived acid-char molybdenum catalyst for reductive deoxygenation of sulfoxidesPublication . Duarte, Tiago A. G.; Mestre, Ana S.; Ferreira, Maria J. G.; Rego, Ana M. Botelho do; Ferraria, Ana M.; Kirillova, Marina V.; Carvalho, Ana P.; Calhorda, Maria José; Fernandes, TiagoThe deoxygenation of sulfoxides is a rather important reaction from both synthetic and biological points of view, due to the potential of sulfides as intermediates in a variety of processes. Homogenous Mo-based catalysts successfully perform the reduction of diphenyl sulfoxide to diphenyl sulfide with high yields but present the well-known limitations regarding recovery and recycling. Thus, in the present work, two new supported catalysts were prepared through the immobilization of molybdenum precursor species (dichlorodioxodi(aquo)molybdenum(VI) and sodium molybdate), onto a sisal-derived acid-char (S13.5), obtained from rope industry wastes by acid-mediated carbonization. The heterogeneous Mo-based materials were characterized by IR spectroscopy, elemental analysis, ICP, solid state NMR, XPS, and SEM, and were evaluated as catalysts for the reduction of sulfoxides to sulfides in the presence of phenylsilane as reducing agent under different reaction conditions. The influence of various experimental parameters, including reducing agent type and amount, solvent type, and acid promoter were investigated. Catalytic studies revealed that both catalysts deoxygenate sulfoxides at 120 °C in toluene solution with high yields (up to 97%). The MoO2Cl2 derived catalyst shown to be highly efficient in the reduction of diaryl, alkylaryl, dibenzyl, and dialkyl sulfoxides to the corresponding sulfoxides using phenylsilane as reductant and no need of acid promoter.
