Engineering the highly efficient heterogeneous catalyst based on PdCu nanoalloy and nitrogen-doped TiCT MXene for ethanol electrooxidation.

Improving the electrocatalytic performance by modulating the surface and interface electronic structure of noble metals is still a research hotspot in electrocatalysis. Herein, we prepared the heterogeneous catalyst based on the well-dispersed PdCu nanoalloy and the N-doped TiCT MXene support (PdCu/N-TiCT) via in situ growth of PdCu nanoparticles on the fantastic N-TiCT sheets. By exploring the electrocatalytic properties of ethanol oxidation reaction (EOR), the composition optimized PdCu/N-TiCT delivers higher mass activity/specific activity/intrinsic activity (2200.

Robust poly(3,4-ethylenedioxythiophene) granules loaded Cu/Ni-doped Pd catalysts for high-efficiency electrooxidation of ethylene glycol.

In our work, poly(3,4-ethylenedioxythiophene) (PEDOT) granules supported Cu/Ni-doped Pd electrocatalysts (PdCu/PEDOT and PdNi/PEDOT) were synthesized for ethylene glycol (EG) oxidation in alkaline medium. The amorphous PEDOT granules as the catalyst supports provide plenty of attachment sites for PdCu and PdNi nanoparticles. The optimized PdCu/PEDOT and PdNi/PEDOT catalysts both perform superior mass-based activity, area-based activity and intrinsic activity for EG oxidation as compared to other control samples.

Bio-Based Coating Materials Derived from Acetoacetylated Soybean Oil and Aromatic Dicarboxaldehydes.

Bio-based coating materials were prepared from epoxidized soybean oil as a renewable source. Acetoacetylated soybean oil was synthesized by the ring-opened and transesterification reaction of epoxidized soybean oil, and its chemical structure was characterized by nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), gel permeation chromatography (GPC), and rheometric viscosity analyses. On the basis of acetoacetylated soybean oil, several bio-based coating materials were prepared using different aromatic dicarboxaldehydes (1,2-benzenedialdehyde, 1,3-benzenedialdehyde, 1,4-phthalaldehyde, 4,4'-biphenyldicarboxaldehyde) and characterized.
