Pre-ELM-11 was obtained from Tokyo Chemical Industry Co. The Pre-ELM-11 was transformed into ELM-11 by heating at 373 K for 10 h under vacuum (< 0.1 mPa), and the CO₂ adsorption isotherms on ELM-11 were measured at 268, 283, and 298 K using the BELSORP-max instrument (MicrotracBel Co.) and a cryostat equipped with a two-stage Gifford–McMahon refrigerator. The cell temperature was kept within ±0.01 K during the adsorption measurements.
MIL-53(Al) was obtained from SyncMOF Inc. The CO₂ adsorption isotherms on MIL-53(Al) were measured at 195, 223, and 273 K using the BELSORP-max instrument (MicrotracBel Co.) and a cryostat equipped with a two-stage Gifford–McMahon refrigerator. The cell temperature was kept within ±0.01 K during the adsorption measurements. Prior to each measurement, MIL-53(Al) was activated by heating it at 473 K for 12 h under a vacuum.

Check if the same lab product or an alternative is used in the 5 most similar protocols

RHA obtained from a rice husk power plant
in Myanmar was used as
the starting material. The chemical composition of the raw RHA was
91.7% SiO₂, 0.8% Al₂O₃, 0.1% Na₂O, 1.8% K₂O, 0.4% CaO, 0.5% Fe₂O₃, 0.5% MgO, and 1.2% P₂O₅. The ignition
loss was 2.9%. Figure 11 shows the preparation process of the RHA adsorbent. The raw RHA
was subjected to mechanochemical treatment using a planetary ball
mill (Fritsch P7), a tungsten carbide container, and a tungsten carbide
grinding medium. The raw RHA samples (2.5 g) were placed in a ball
milling container and subjected to mechanochemical treatment at a
rotation speed of 500 rpm for 15, 30, and 60 min.
The powder XRD patterns of the samples were obtained using Cu Kα
radiation with a diffractometer (Rigaku, RINT 2000). FTIR spectra
were recorded on an FTIR-4100 spectrometer (JASCO, Japan). The particle
morphologies of the samples were examined using FE-SEM (Hitachi, S-4700).
The N₂ adsorption–desorption isotherms of the samples
were measured at 77 K using a BELSORP-max instrument (MicrotracBEL,
Japan).

Comprehensive Characterization of NG/CB-x Catalyst

Check if the same lab product or an alternative is used in the 5 most similar protocols

The morphology of NG/CB-x was determined by scanning electronic microscopy (SEM; JSM-7800F, JEOL, Tokyo, Japan) and transmission electronic microscopy (TEM; Zeiss LIBRA 200 FE, Oberkochen, Germany). The crystal of the catalyst was characterized by X-ray diffraction (XRD) using Cu Kα radiation (40 kV and 40 mA) implemented with a D8 advance diffractometer (1.54056 Å, Bruker, Bruker Beijing Office, China). The 2θ ranged from 10° to 90° at a scan rate of 0.02° and a fixed acquisition time of 0.1 s. The defection degree of carbon was acquired using an inVia Raman microspectrometer (Renishaw, Wharton-Ander Edge, UK) at 532 nm. X-ray photoelectron spectra (XPS) were carried out on ESCALAB 250Xi (Thermo Fisher Scientific, Waltham, MA, USA) X-ray photoelectron spectroscope using monochromatic Al Kα radiation at 1486.6 eV. The data for each atom and band deconvolution were fitted with the ‘XPS peak’ software, and the C1s peak at 284.8 eV was used as an internal standard. The Brunauer-Emmett-Teller (BET) surface area was obtained from 77 K N₂ sorption isotherms using a Belsorp-max instrument (MicrotracBEL, Osaka, Japan). Pore size distribution was calculated according to Barett–Joyner–Halenda (BJH) model, and the t-plot method was used to extract the microporous surface area and volume.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
