“…Then, 30 min after adding a volume of 0.3 mL of hydrazine hydrate (30%) to the mixture, it was transferred into a Teflon-lined autoclave made of stainless steel, which was stored in an oven for 4 h at 140 °C. An external magnet was used to collect the acquired black product, which was then rinsed three times using distilled water and ethanol (3 × 20 mL) …”

In the present research, using ethylenediamine and hydrazine hydrate as the capping and reducing agents in this investigation, respectively, Ag–Cu–Ni NPs were immobilized on the functionalized g–C3N4 surface. This nanocatalyst was studied in terms of its catalytic activities for the A3-coupling reaction to synthesize propargylamine derivatives. According to the results, in the presence of 1 mL of toluene as the solvent and 20 mg of the g–C3N4–TCT–2AEDSEA–Ag–Cu–Ni nanocatalyst, the maximum efficiency of the nanocatalyst occurred at a temperature of 80 °C. Products were purified using thin-layer chromatography plates (silica gel) by employing n-hexane/ethyl acetate with a 90:10 ratio. In addition, the prominent benefits of the synthesized nanocatalyst include its high yields of the product, cost-effectiveness, recyclability, and easy separation. The novelty of the catalyst is due to the presence of Ag–Cu–Ni nanoparticles at the same time in the structure of the functionalized g–C3N4 substrate. So, Ag–Cu–Ni can be strongly connected to the substrate. The structure of the synthesized nanocatalyst was characterized using Fourier transformed infrared spectroscopy, X-ray powder diffraction, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, vibrating-sample magnetometry, and transmission electron microscopy.

During this study, an easy procedure is presented for the preparation of a new nickel ion-containing DABCO based ionic liquid. The prepared reagent was characterized using FT-IR, FESEM, EDX, XRD, ICP-OES, TGA and DRS analyses. In continue the catalytic activity of this reagent which is formulated as [C 4 (DABCO) 2 ].NiCl 4 was investigated in the reduction of a variety of carbonyl compounds to their corresponding alcohols with NaBH 4 . The promoting ability of this catalyst was also confirmed in the acetylation of alcohols with CH 3 COCl. All reactions were carried out in short times with high to excellent yields. The catalyst was also recoverable and reusable in the studied reactions.

“…Since no activation process is involved, most studies show that biochar's structure is monopolized by microporosity (Chu et al, 2018;Wang et al, 2018;Zhang X. et al, 2021). Therefore, biochar is suitable to store gases such as sulfur dioxide, SO 2 (Braghiroli et al, 2019;Zhang et al, 2020), CO 2 (Huang et al, 2019;Yan et al, 2021), hydrogen sulfide, H 2 S (Ma et al, 2021), and methane, CH 4 (La et al, 2019;Alimohammadi et al, 2022;Shahabi Nejad and Sheibani, 2022;Zarei et al, 2022). In terms of definition, biochar is a black carbonaceous material produced from biomass through heat treatment at temperatures higher than 250 °C in the absence of air or limited air (Ben Salem et al, 2021).…”

Textile dyes are organic compounds that can pose an environmental threat if not properly treated. They can cause many problems ranging from human health, ecosystem disturbances, and the reduction of the esthetic value of water bodies. The adsorption process using activated carbon (AC) has been proven to be effective in treating dyes in wastewater. However, the production of AC is limited by the non-renewables and relatively expensive precursor of coal. Date palm residues (DPRs) provide a good alternative for AC’s precursor due to their continuous supply, availability in a large amount, and having good physiochemical properties such as high oxygen element and fixed carbon. This study provides a review of the potential of date palm residues (DPRs) as AC in adsorbing textile dyes and the recent technological advances adopted by researchers in producing DPR-based AC. This review article focuses solely on DPR and not on other biomass waste. This study presents a background review on date palms, textile dyes, biochar, and AC, followed by production methods of AC. In the literature, DPR was carbonized between 250 and 400°C. The conventional heating process employed an activation temperature of 576.85–900°C for physical activation and a maximum of 800°C for physicochemical activation. Chemical agents used in the chemical activation of DPR included NaOH, KOH, ZnCl2, H3PO4, and CaCl2. The maximum surface area obtained for DPR-AC was 1,092.34 and 950 m2/g for physical and chemical activation, respectively. On the other hand, conditions used in microwave heating were between 540 and 700 W, which resulted in a surface area of 1,123 m2/g. Hydrothermal carbonization (HTC) utilized carbonization temperatures between 150 and 250°C with pressure between 1 and 5 MPa, thus resulting in a surface area between 125.50 and 139.50 m2/g. Isotherm and kinetic models employed in the literature are also discussed, together with the explanation of parameters accompanied by these models. The conversion of DPR into AC was noticed to be more efficient with the advancement of activation methods over the years.
