“…The observed adsorptiondesorption isotherm was type IV which indicate the mesoporous behaviour of the catalyst. [54,55] The surface area of ZnOÀ Cu (OH)Cl/MCM-41 nanoparticles with 2.46 wt% zinc and 6.39 wt% copper calculated with the Brunauer-Emmett-Teller (BET) equation was 239.079 m 2 /g, and pore volume is 0.743 cc/g and pore Full Paper diameter 3.055 nm. The surface area for MCM-41 is approximate 1000 m 2 /g and the pore volume 0.98 cc/g and pore diameter 4 nm which decreases after incorporation of metal inside the pore of the MCM-41.…”

MCM-41-supported ZnOÀ Cu(OH)Cl nanoparticles were synthesized via an incipient wetness impregnation technique using zinc chloride and copper chloride salts as well as water at room temperature. The catalyst was characterized by powder X-ray diffraction (PXRD), infrared spectroscopy (IR), and TGA, whereas surface and morphological studies were performed by using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The above studies revealed the incorporation of metal species into the pores of MCM-41, leading to a decrease in surface area of the nanoparticles that was found to be 239.079 m 2 /g. The substituents attached to the ketone determine the rate of the reaction, and the utilization of the green solvent 'water' astonishingly completes the hydrogenation reaction in 45 minutes at 40°C with 100% conversion and 100% selectivity as analyzed by gas chromatography-mass spectrometry. Hence, ZnOÀ Cu(OH)Cl/MCM-41 nanoparticles with 2.46 wt% zinc and 6.39 wt% copper were demonstrated as an active catalyst for the reduction of ketones without using any gaseous hydrogen source making it highly efficient as well as environmentally and economically benign.

Glycine‐functionalized reduced graphene oxide (GRGO) was prepared through the reaction of glycine and chlorine‐functionalized reduced graphene oxide. The product was characterized by SEM, HRTEM, IR, Raman, and XPS. The nitrogen content (8.28%) was high in product, peak at 285.8 eV was assigned to the C–N bond, which implied that the chlorine residues in raw material were substituted by amine group of glycine. The intensity ratio of D and G peak was about 1.5, which also implied that more saturated carbon atoms were present in the product. Results of SEM, IR, and XPS confirmed that glycine molecules were attached to graphene sheets. Compared with reduced graphene oxide (61.5 mg/g) and active carbon (45.2 mg/g), GRGO had a good adsorption capacity (98.9 mg/g) for methylene blue. The adsorption process was fitted to three kinetic models and three adsorption isotherm models. The adsorption process complied with pseudo‐second order kinetic model and Langmuir model.
