The electrocatalytic (EC) CO₂ reduction (CO₂R) can be exploited for the energy transition and to store C into valuable products like syngas (H₂/CO mixtures), organic acids (formic acid) and chemicals/fuels (C₁₊ alcohols).¹ A big challenge for the industrialization of this technology is to find low-cost electrocatalyst, efficient reactors and process conditions. Noble metals like Ag and Au are the most used ones for syngas production.² To reduce the catalyst cost, we developed electrodes made of Ag nanoparticles (NPs) on TiO₂ nanotubes (NTs),³ showing a higher electrochemical surface area and electrons transport than a bare Ag. Titania was used as an efficient support, for enhancing the stability of key CO₂^- radical intermediate and decreasing the EC CO₂R overpotential. We are also exploiting the current knowledge of the thermocatalytic CO₂ hydrogenation to develop noble-metal-free CO₂R electrocatalysts.^4–6 For instance, Cu/Zn/Al-based catalysts producing methanol and CO from the CO₂ thermocatalytic (TC) hydrogenation (at H₂ pressure (P) of 30 bar and temperature (T) > 200 ^oC) generates H₂, CO and other C₁ to C₃ liquid products during the electrochemical CO₂R in a gas-diffusion-electrode system; while operating in the liquid phase, the same catalyst produces syngas with a tunable composition (depending on the applied potential) and other liquid C₂₊ products (in both cases at ambient T,P). Our results open a promising path for the prospective implementation of metal-oxides nanostructures for the CO₂ conversion to the chemicals and fuels of the future. From an environmental and technoeconomic analysis applied to the case of study of the scaled-up  methanol production, including downstream purification processes, we determined that optimized EC process conditions could lead to a practical implementation of this technology; that is, recirculation of the not reacted CO₂, achievement of current densities in the range of 100-200 mA/cm² with faradaic efficiencies (> 90%), and use of renewable electricity sources (i.e. 30% of the total energy).⁴  Hence, considering the effective allocation of methanol on a real market scenario, the EC process results to be economically advantageous over the TC one at productivity scales as low as 19.1 kg/h, and could lead to a carbon footprint that is comparable to that of current industrial technologies for methanol production (climate change impact of 2.72 kgCO₂/kgCH₃OH). Moreover, in a scenario with a 100% renewable energy such as photovoltaic, it is possible to reach savings in that carbon footprint of up to 62%.
