The adsorption of furfural on SrTiO3 and SrCoxTi1-xO3 perovskites: A DFT study within the molecular cluster approach

Biomass-derived 2-methyltetrahydrofuran platform: a focus on precious and non-precious metal-based catalysts for the biorefinery

“…The drawbacks of the non-precious metals towards hydrogenation which is vital for MTHF formation have increased the interest in research on intermetallic catalysts, especially bimetallic ones. 257 The drawbacks occur especially with monometallic catalysts, as they lack the tunability of active sites. The performance or activity of bimetallic catalysts is not solely attributable to the presence of active sites.…”

“…Perovskites are easily tunable, thus, the metal constituent can be easily substituted, bringing about new oxidation states and oxygen vacancies, which is appropriate for catalytic activity. 257 A notable application of perovskites in biomass conversion research is the reforming of hydrogen from tar. 329–332 The possibility of hydrogen production from tars using perovskites is due to their alkali and alkaline earth metals content.…”

“…The intermetallic arrangement in perovskites can enhance hydrogenation selectivity compared with single-metal catalysts. 257,339 However, there is not a single publication yet on the direct conversion of any biomass constituent to MTHF as the main product on perovskites. If a comparison can be made based on the intermediates or the main hydrogenation products formed, where there is the possibility of further hydrogenation or hydrodeoxygenation to form MTHF, close similarities can be drawn to selected publications.…”

Prediction of Europium Retention in Perovskite: Potential Candidates for an Engineering Barrier in the Disposal of Radioactive Waste

“…e europium sorption isotherms as a function of time were developed by estimating the concentration of europium nitrate retained in tausonite at different contact times (1,2,3,4,5,7,16,18,20,22,24, and 48 h). Sorption kinetics were modelled using pseudo-order expressions (0.5 ≤ n ≤ 2), based on the reduced Van't Hoff equation (see equation (1)) and compared with empirical pseudo-first-order model (Lagergren and Elovich equation), pseudo-second-order, and intraparticle diffusion.…”

“…Perovskites are crystalline metal oxides with the general formula ABO 3 , in which A can be rare earth (mainly lanthanides) or an alkali or alkaline earth metal and B is a transition metal [1,2]. ese oxides are excellent light absorbers and their properties include tunable band gaps, low exciton binding energy, high carrier mobility, long diffusion length, and so on [3], and, also, they have a narrow band gap (semiconductor), for which they could be considered as good candidates for thermoelectric generators [4,5].…”
