Summary: The present study successfully synthesized highly porous TiO2 by incorporating PANI polymer into the sol-gel chemistry of TiO2/TTIP. The TP samples exhibited a porous ginger-like nanostructure with smaller particle size compared to pristine TiO2. XPS analysis confirmed the presence of hydrogen bonds between Ti-OH groups of TiO2 and protonated nitrogen of PANI. UV-visible absorption study showed a small shift in absorption wavelength for TP8 sample and a reduction in Eg value. FTIR results confirmed the interaction between PANI and TiO2. The TP8 sample showed high photocatalytic activity towards Methylene blue dye degradation. The study offers an excellent photocatalyst TP8 with 8 wt% of PANI for the degradation of MB dye. Evaluation: 8 points

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
