Summary: The large number of phenolic compounds in coal tar and coal-converted oil increases the cost and difficulty of processing and transportation. Efficient separation methods for phenolic compounds are of great industrial significance. By introducing hydroxyl functional groups into the cations of ionic liquids, eight ionic liquids were synthesized and their separation properties for phenol in model oil were studied. The hydroxyl modified ionic liquids showed good extraction performance for phenol, with choline propionate ionic liquids exhibiting the best separating capacity.

Summary: Researchers have successfully assembled a self-powered energy system that utilizes solar energy to generate hydrogen gas and overcomes the limitations of intermittent sunlight. The system consists of stable output voltage zinc-air batteries, solar cells, and a water splitting electrolyzer. The solar cells charge the zinc-air batteries during light reaction, which can then release electric energy to drive hydrogen production without external input. The solar-to-hydrogen efficiency and solar-to-water splitting device efficiency of the system are 4.6% and 5.9%, respectively.

Summary: We have developed a composite catalyst with an acid and base interface that efficiently converts ethanol to butanol. The catalyst exhibits a significant increase in dehydrogenation and condensation rates per site compared to a physical mixture of acid and base, showing a remarkable acid-base synergistic effect. Through isotope experiments, we have uncovered the chemical origin of the strong activation of the C-H bond under cooperative catalysis, providing valuable insights into catalyst design for C-H activation.

Summary: Selective hydrogenation of phenol to cyclohexanone is studied to understand the catalytic mechanism and selectivity discrepancy on noble metal catalysts. Results show that different reaction pathways converge to the formation of cyclohexanone under mild conditions. The selectivity discrepancy depends on the activity for cyclohexanone sequential hydrogenation, which is influenced by hydrogenation energy barrier and competitive chemisorption between phenol and cyclohexanone.
