The photocatalytic properties of a material predominantly depend upon the material fabrication. In the last few years, sulfide based nanomaterials were used for their extraordinary efficiency due to their structural and morphological features. Present work is focused on the preparation of bimetallic layered molybdenum‐wurtzite zinc sulfide heterostructure by facile hydrothermal method. The prepared MoS2−ZnS was characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer‐Emmett‐Teller (BET) surface analysis and X‐ray photoelectron spectroscopy (XPS). MoS2−ZnS showed high photocatalytic hydrogen evolution reaction (HER) and dye degradation compared to pure ZnS and MoS2. The synergistic effect of layered MoS2 and wurtzite ZnS would have amplified the photocatalytic HER activity and degradation of crystal violet dye under visible light irradiation; the electron‐hole recombination was significantly reduced due to the heterostructured arrangement of MoS2‐ wurtzite ZnS

Although there are many reports on the synthesis of quinazolinones, the use of high boiling solvents and high temperature restricts their scale-upt ot he industrial level. The current research reveals as imple protocolf or the catalytic synthesis of quinazolines in the presence of a cost-effective and reusable mesoporous ZrO 2 -supported Cu 2 O( Cu 2 ZrO 3 )c atalyst. The catalyst was prepared by simple co-precipitation and characterized using techniques like XRD, TGA, BET,S EM and TEM. The catalyst was reused for five cycles without significant loss in the activity and the catalyst was truly heterogeneous. The present synthesis utilizes environmentally benign H 2 O 2 as an oxidant. The present protocol showed good tolerance for various substituted aldehydes and good yields for quinazolinone derivatives. The methodf ollowed as imple workup procedure and no column chromatography was needed.Scheme1.Quinazolinone synthesis a)Anthranilamide with aromatic ketones. b)Anthranilamide with aromatic halides. c)Anthranilamide with aldehydes under mild conditions.[a] L.

Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.006 Å; disorder in main residue; R factor = 0.104; wR factor = 0.316; data-to-parameter ratio = 12.2.The title compound, C 31 H 27 F 3 O 7 , is a liquid crystal and exhibits enantiotropic SmA and nematic phase transitions. In the crystal, the the 2H-chromene ring system makes dihedral angles of 54.46 (17) and 7.79 (16) , respectively, with the central benzene ring and 4-(heptyloxy)benzene ring. The three F atoms of the -CF 3 group are disordered over two sets of sites, with an occupancy ratio of 0.62 (3):0.38 (3). The crystal structre features two pairs of C-HÁ Á ÁO hydrogen bonds, which form inversion dimers and generate R 2 2 (10) and R 2 2 (30) ring patterns. C-HÁ Á ÁO interactions along [100] and C-HÁ Á Á interactions futher consolidate the packing, leading to a three-dimensional network. Related literature

N-(2-Chloro-5-cyanophenyl)-4,4,4-trifluorobutanamide (3) was synthesized by reacting 4,4,4-trifluorobutanoic acid (1) with 2-amino-4-chlorobenzonitrile (2) in the presence of triethylamine and propylphosphonic anhydride in ethyl acetate. Character­ization of the compound was done by IR, 1H-NMR, 13C-NMR, LC-MS and CHN analysis
