In this work, we report a facile method for the synthesis of Co3O4–functionalized carbon nanotube (Co3O4–f-CNT) composite via growth Co3O4 nanoparticles on surface functionalized nanotubes (f-CNTs) by thermal decomposition cobalt nitrate hexahydrate in ethanol. The consists 13% and 87% weight, all particles grew compactly along axis with highly uniform dispersion. When used as an anode material rechargeable lithium ion batteries, manifested high capacities excellent cycling performance at...
Urea derivatives are obtained in mild to good yield from the reactions of primary aliphatic amines with CO2 absence any catalysts, organic solvents or other additives. To optimize reaction conditions, experimental variables including temperature, pressure, concentration amine, time etc. were studied. Satisfactory yields at optimized conditions that comparable presence catalyst and solvent. The preliminary investigation mechanism showed alkyl ammonium carbamate was quickly formed as...
SnS2/graphene nanosheets (SnS2/GNS) composites were synthesized by a one-step hydrothermal method. The exhibit remarkably improved Li-storage ability with good cycling life and high capability superior to that of the pure SnS2 counterpart due synergic effect between graphene nanosheets.
A green route to synthesize a self-healing polyurethane-urea Diels–Alder adduct (PUUa-DA) using CO<sub>2</sub> and furfuryl amine as renewable feedstocks is reported.
The selective hydrodeoxygenation of lignin-derived guaiacol to value-added products, especially phenol, under relatively mild reaction conditions remains an important challenge. A Cl-modified Ru/TiO2 catalyst exhibited higher phenol selectivity compared with unmodified one in the conversion 1,4-dioxane at 240 °C and 1 MPa H2. Unlike Ru/TiO2, modified a modest activity demethoxylation producing but inferior ability hydrogenation its aromatic ring, resulting much slower consumption phenol. Cl...
Hydrodeoxygenation of lignin-derived guaiacol to aromatic products under mild conditions was achieved using an interesting Pt/TiO2-D catalyst. The defects in TiO2-D played a pivotal role H2 dissociation and exhibited unique capability for the migration active H species on surface within bulk phase TiO2-D, resulting formation "H reservoir" adjacent Pt sites. Consequently, superb activity cleavage C–O bond extremely low hydrogen concentration (1 atm 10% H2/Ar). Moreover, H−migration into...
Polyureas were synthesized from diamines and carbon dioxide in the absence of any catalyst or solvent, analogous to synthesis urea condensation ammonia with dioxide. The method used as a carbonyl source substitute highly toxic isocyanates for polyureas. FTIR DFT calculations confirmed that strong bidentate hydrogen bonds formed between motifs, XRD patterns showed PUas crystalline network structure through bonds, which served physical cross-links. long chain presented microphase separated...
Highly concentrated microcrystalline cellulose was directly converted to isosorbide with yields of 35–50%, providing a new approach for producing important fine chemicals from biomass.

Activation and transformation of CO2 is one the important issues in field green sustainable chemistry. Herein, as a carbon-oxygen resource was converted to CO2-polyurea with 1,6-hexanediamine through two-step polymerization. The reaction parameters such temperature, pressure time were examined; several kinds catalysts screened absence presence NMP solvent. formed oligomer final polyurea characterized by FT-IR, VT-DRIFTS, NMR, XRD, AFM their thermal properties examined TGA DSC. It confirmed...
The surface of Pd particles is modified by pyridine and this promotes the hydrogenation CO in CAL over Pd/C.

A new concept of steaming multiwalled carbon nanotubes (MWCNTs) via acid vapour was presented for controllable nanoengineering the MWCNTs. This method is more simple, effective, precisely-controllable and environmentally-friendly compared to traditional ones. Moreover, novel porous nanotubes, named nanoflutes, were fabricated based on this strategy.
The salt effect of NaxA (A = SO42−, Cl−, NO3−, etc.) on the hydrothermal carbonization biomass is reported.
