In this work, the solution and diffusion properties of n-heptane, thiophene, 2-methylthiophene, 2,5-dimethylthiophene, ethyl sulfide, butyl mercaptan in poly[bis(phenoxy)phosphazene] (PBPP) werestudied by inverse gas chromatography. The infinite dilute activity coefficients and diffusion coefficientswere determined. Effects of temperatures and solvent species on the activity coefficients and diffusioncoefficients were investigated. The results showed that higher temperature was beneficial for bothsolution and diffusion process. Compared with pervaporation desulfurization performance in ourprevious work, the order of infinite dilute diffusion coefficients was in agreement with that of partialflux, which indicated that diffusion decided the permeability within solution–diffusion model.

This work reveals a schematic strategy to massively fabricate a series of OH-riched copper oxides (CuO-OH), which could be used as highly efficient chemo catalysts for water oxidation reaction (WOR). The results indicate that the as-prepared CuO-OH exhibited excellent catalytic activity (2,900 µmol·h−1·g−1) toward water oxidation, far higher than the pure CuO formed through calcination. According to the radical capture results and the DRIFTS, XRD, and Raman spectra data, sulfate radicals were the main active species. Subsequent data of BET, HR-TEM, and FT-IR spectra reveal that the CuO-OH could activate persulfate ions in the dark to produce sulfate radicals efficiently at room temperature and promote the sulfate radicals to carry out immediately to hydroxide-mediated deprotonation steps in WOR. Based on the results above, a mechanism is proposed.
