“…Characterization of 1 was accomplished with the usual BET, BJH, SEM-EDX, and FTIR techniques. Specific surface area and pore sizes distribution of 1 were evaluated with Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) methods [12]. Analyses in Table 1 confirmed that a change in pore sizes after reactions occurred, especially after the heat treatment at 400 • C. Notably, after the third cycle, catalytic material displays a surface area 10 times larger than the pristine sample, and a doubled pore area.…”

For the first time, secondary steel slag, the material directly coming from ladle treatments, is used as a catalyst for the biodiesel production without undergoing any preliminary chemical or thermal modifications. Catalytic material 1, which has been pre-ground to sizes below 230 mesh, has been characterized for the surface textural properties and used as a catalyst in the transesterification of triglycerides of soybean oil to produce biodiesel. Reaction conditions were optimized by DOE method, revealing no interdependence between reaction parameters and results, and showed a catalytic activity comparable with that of an analogous slag-deriving catalyst reported in the literature.

“…Lanthanide (Ln) elements have been studied extensively in diverse industrial applications of magnets, high-k gate dielectrics, display materials, catalysts, and batteries [1][2][3][4][5][6]. For recycling used Ln materials, various recovery methods for Ln elements have also been demonstrated [7][8][9][10][11][12][13].…”

Electrochemical coating and recovery by electrodeposition have been invaluably employed for facial thin film fabrication and the recycling of used materials. Herein, we have established a full data set of lanthanide (Ln: La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, and Yb) elements electrodeposited on carbon sheets. Cyclic voltammetry was performed for 10 mM Ln(III) ions in a 0.1 M NaClO4 electrolyte over a carbon sheet between +0.5 V and −1.7 V (vs. Ag/AgCl). Amperometry was performed at a given potential to electrodeposit the Ln element on the carbon sheet. Their physicochemical properties were fully investigated by scanning electron microscopy, Fourier-transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and X-ray photoelectron spectroscopy. The newly established full data set for Ln(III) ions over carbon electrodes provides useful fundamental information for the development of coating and recovery methods of Ln elements.

“…Following our ongoing interest in developing green methods obeying circular economy principles [ 20 , 21 ], the aim of this work was the development of a protocol that reached two important advantages: (i) exploits municipal waste never used before (e.g., used pants and diapers, newspaper, and soybean peels) as a source of cellulose, and (ii) makes the hydrothermal treatment of cellulose more sustainable by employing less aggressive acid catalysts that are also non-critical materials such as H 3 PO 4 [ 11 ], CH 3 COOH, and scandium(III) triflate [ 19 ], in order to obtain precious chemicals (HMF, LA, AMF, and furfural) [ 2 , 22 ].…”

Eco-Friendly Catalytic Synthesis of Top Value Chemicals from Valorization of Cellulose Waste

The total amount of cellulose from paper, wood, food, and other human activity waste produced in the EU is in the order of 900 million tons per year. This resource represents a sizable opportunity to produce renewable chemicals and energy. This paper reports, unprecedently in the literature, the usage of four different urban wastes such as cigarette butts, sanitary pant diapers, newspapers, and soybean peels as cellulose fonts to produce valuable industrial intermediates such as levulinic acid (LA), 5-acetoxymethyl-2-furaldehyde (AMF), 5-(hydroxymethyl)furfural (HMF), and furfural. The process is accomplished by the hydrothermal treatment of cellulosic waste using both Brønsted and Lewis acid catalysts such as CH3COOH (2.5–5.7 M), H3PO4 (15%), and Sc(OTf)3 (20% w:w), thus obtaining HMF (22%), AMF (38%), LA (25–46%), and furfural (22%) with good selectivity and under relatively mild conditions (T = 200 °C, time = 2 h). These final products can be employed in several chemical sectors, for example, as solvents, fuels, and for new materials as a monomer precursor. The characterization of matrices was accomplished by FTIR and LCSM analyses, demonstrating the influence of morphology on reactivity. The low e-factor values and the easy scale up render this protocol suitable for industrial applications.
