Abstract White rice husk silica (RHS) was used as a silica source for ZSM-12 (MTW) zeolite synthesis. The ZSM-12 zeolite derived from RHS was prepared by hydrothermal method at 150°C. MOF-74(Zn) metal–organic framework (MOF) as a shell was growth over zeolite ZSM-12 as a core at room temperature. The ZSM-12@MOF-74 core@shell was used as a visible light driven photocatalyst for degradation of methylene blue (MB). The materials were characterized using a range of techniques. The ZSM-12@MOF-74 core@shell indicated the highest photocatalytic activity. Degradation mechanism was attributed to electrons and holes are generated in the organic ligand. The core@shell was extremely stable during five cycle test and did not demonstrate any explicit loss of photocatalytic activity during five cycle tests. The used adsorbent can be reused for adsorptive removal through simply washing.

Aim and Objective: During the investigation of sodium nitrite-catalyzed oxidative coupling reaction of aryls, an unprecedented C(sp2)-H and C(sp3)-H coupling of substituted 2-aryl acetonitrile was found. Materials and Methods: The structure of the coupled product was confirmed by 1H and 13C NMR spectroscopy and high-resolution mass spectrometry (HRMS), and comparison of its derivatives with known compounds. The effects of methoxy group in the benzene ring on the reaction were evaluated. Results: The optimized reaction conditions are summarized as follows: CF3SO3H/substrate = 1.5 equiv., NaNO2/substrate = 0.3 equiv., CH3CN as solvent. 2-(4-Methoxyphenyl)acetonitrile and 2-(3,4,5- trimethoxyphenyl)acetonitrile could also generate C(sp2)-H and C(sp3)-H coupling. The coupling reaction occurred as a typical radial mechanism. Conclusion: An unprecedented cyano-induced, NaNO2-catalyzed oxidative C(sp3)-H and C(sp2)-H coupling was reported. The reaction proceeded under very mild conditions, using O2 in the air as terminal oxidant. The unique oxidative manner might provide more inspiration for the development of intriguing oxidative coupling reactions.
