ELECTROCHEMICAL CONVERSION OF CARBON DIOXIDE TO FORMIC ACID IN A PRESSURIZZED FILTER PRESS CELL
2018
To limit the negative effect of carbon dioxide as a greenhouse gas, an interesting approach is the utilization of Carbon Capture and Conversion (CCC) methodology, which is focused on the use of CO2 waste as a feedstock to produce added-value product by using the excess electric energy from renewable source [1]. In this framework, an increasing attention has been devoted in the electrochemical conversion of carbon dioxide to formic acid in water [2,3], which is considered one of the more attractive pathway to convert CO2. Since the main hurdle of the CO2 reduction from aqueous solution is the low CO2 solubility in water, in this work, the effect of some operating parameters, including pressu…
From smart to lean : how to design for better cities, happier citizens and save the world
2018
Come è possibile progettare città più “sostenibili”, “resilienti” e “smart” in un’era di scarsità di risorse, profondi conflitti sociali ed epocali emergenze ambientali? Le nuove e complesse sfide urbane stanno profondamente cambiando il ruolo di progettisti e pianificatori, sempre più “designer/manager” di un costante processo di revisione di tutto ciò che concerne l’habitat umano. Indagando in modo cross-disciplinare il complesso sistema di relazioni fra uomo, città e risorse naturali, si presenta un nuovo approccio a progetto e attuazione delle politiche urbane per la sostenibilità ambientale e sociale. Un approccio manageriale mutuato dall’ambito della gestione di imprese e l’innovazion…
CO2 Reduction in Gas-Solis Regime by Using GaP/TiO2 as Photocatalyst

ZrO2 Based materials as photocatalysts for 2-propanol oxidation by using UV and solar light irradiation and tests for CO2 reduction
2018
Abstract Bare ZrO2, Ce doped ZrO2 and Er doped ZrO2 samples have been prepared by a hydrothermal process and have been used as photocatalysts for 2-propanol oxidation reaction in gas solid regime. Moreover, some preliminary tests have been carried out for CO2 reduction. The samples were physico-chemically characterized and both bare and doped ZrO2 based materials resulted active for oxidation and reduction reactions by using UV and solar irradiation. The reactivity results have been correlated with the compositional, structural and morphological features of the photocatalysts.
The Shift toward a Sustainable Urban Mobility through Decision Support Systems
2017
This chapter examines Decision support systems (DSS) are instrumental in the sustainable development of urban mobility, as they are useful to each decision maker to better predict, evaluate, and measure the impact of alternative solutions and to take informed and evidence-based decisions. It presents a number of DSSs explaining how sustainable mobility targets could be reached through these systems. The chapter highlights the transition toward a more sustainable mobility model not only comprises innovation at vehicle or infrastructure level, but also requires interdisciplinary and cross-sectorial expertise together with effective decision making support. When a DSS for sustainable urban mob…
Electrochemical conversion of carbon dioxide in pressurized electrochemical cells
2019
To limit the negative effect of carbon dioxide as a greenhouse gas, an interesting approach is the utilization of Carbon Capture and Conversion (CCC) methodology, which is focused on the use of CO2 waste as a feedstock to produce added-value products by using the excess electric energy from renewable source [1]. In this framework, an increasing attention has been devoted to the electrochemical conversion of carbon dioxide to formic acid in water [2-3] or CO [1]. Since the main hurdle of the CO2 reduction from aqueous solution is the low CO2 solubility in water, in this work, the utilization of pressurized electrochemical cells is evaluated. The effect of various operating parameters, includ…
