Surface properties vs activity of meso-ZrO2 catalyst in chemoselective Meerwein-Ponndorf-Verley reduction of citral: Effect of calcination temperature

Synthesis and Characterization of Nickel(II) Homogeneous and Supported Complexes for the Hydrogenation of Furfural to Furfuryl Alcohol

“…The pore volume decreased from 0.69 cm 3 /g of SiO 2 to 0.39 cm 3 /g (Si-1) and 0.27 cm 3 /g (Si-2), which might be due to pores collapsing at elevated temperatures during synthesis. The physisorption isotherms (Figure 4a) are typical of type IV based on the literature reported IUPAC classification [24]; this confirms that the synthesized complexes are mesoporous. The pore diameter of complex C3 (4.63 nm) and C6 (4.21 nm), as shown in Figure 4b, falls within the range for mesoporous materials (2 nm < size < 50 nm) 22 , which also confirms that complexes Si-1 and Si-2 are mesoporous.…”

Catalytic Conversion of CO2 to Formate Promoted by a Biochar-Supported Nickel Catalyst Sourced from Nickel Phytoextraction Using Cyanogen-Rich Cassava

“…The N 2 adsorption isotherm observed for Ni@CassCat is typical of a type IV isotherm, suggesting that the catalyst is a mesoporous material (Figure 4a). 33 Figure 4b is also a confirmation of the mesoporosity of the material with Ni@CassCat and the control having pore sizes of 25.85 and 16.34 nm, respectively. There was pore enlargement in Ni@CassCat compared to the control.…”

“…The textural features of both the catalyst and control samples were deduced by the nitrogen physisorption method (Table S3 of the Supporting Information). The N 2 adsorption isotherm observed for Ni@CassCat is typical of a type IV isotherm, suggesting that the catalyst is a mesoporous material (Figure a) Figure b is also a confirmation of the mesoporosity of the material with Ni@CassCat and the control having pore sizes of 25.85 and 16.34 nm, respectively.…”

Metal-doped mesoporous ZrO2catalyzed chemoselective synthesis of allylic alcohols from Meerwein–Ponndorf–Verley reduction of α,β-unsaturated aldehydes

“…5. A similar chair-like CO 2 -TPD profile was reported for ZrO 2 44 and Cu/ZrO 2 /CaO. 45 The base concentrations of the prepared catalysts ranged from 0.3-1.1 mmol CO 2 g À1 .…”
