“…The β-1,4-glycosidic bonds of cellulose make it a durable support for the formation of catalytically active nanocomposites with inorganic substances [ 12 ]. Nanocomposites produced from nanopolymers and inorganic nanoparticles offer the advantages of natural abundance and biodegradability, often benefitting from the synergy between their components [ 13 ], as exemplified by the numerous synthetic applications of cellulose-based catalysts (e.g., Pd/cellulose nanocomposites [ 14 ], γ-Fe 2 O 3 /Cu@cellulose [ 15 ], magnetic nanocellulose [ 13 ], cellulose/ZrO 2 [ 16 ] and cellulose@Fe 2 O 3 [ 17 ]…”

The depletion of fossil fuels calls for the development of renewable alternatives such as biodiesel and has inspired much research on catalysts for the production of biodiesel through the esterification of biomass-derived materials. Herein, a green heterogeneous catalyst for highly efficient biodiesel synthesis was fabricated from rice straw–derived cellulose, hematite, and zirconia and was shown to contain porous irregularly shaped α-Fe 2 O 3 –ZrO 2 composites (average particle size = 42.5 nm) evenly distributed on the nanocellulose surface. The optimal catalyst (nanocellulose:α-Fe 2 O 3 –ZrO 2 = 2:1, w/w) afforded biodiesel in a yield of 92.50% and with specifications close to those prescribed by international standards. This catalyst could be reused for up to five cycles without a marked activity loss, with the biodiesel yield in the fifth cycle equaling 80.0%. The developed nanocomposite holds great promise for cutting the costs of biodiesel production, as it is derived from biodegradable raw materials and is renewable, non-corrosive, easy to handle, and green. In addition, the large-scale discharge of this catalyst after use does not pose a hazard to the environment.

“…1e, the four diffraction peaks at 2h = 14.87°, 16.59°, 22.92°and 34.38°w ere observed both for the silver nanoparticles coated and uncoated filter paper. They correspond to (1-10), (110), (200), and (004) planes of cellulose-I structure, respectively [35,36]. This shows that the crystalline structure of cellulose remained intact within those chemical treatments.…”

Nanozymes are nanomaterials that possess intrinsic enzyme mimicking activity. In this study, the application of silver nanoparticles coated filter paper (AgNPs/FP) that exhibits a peroxidase-like catalytic activity as a potential sensor is reported. A simple chemical reduction method was used to produce AgNPs/FP. The formation of the particles on filter paper were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), and surface-enhanced Raman spectroscopy (SERS). In the presence of hydrogen peroxide, AgNPs/FP oxidized the colorless o-phenylenediamine (OPD) and 3,3 0 ,5,5 0 -tetramethylbenzidine (TMB) solutions to a yellow colored 2,3-diaminophenazine (DAP) and deep blue colored oxidized TMB (oxTMB), respectively. In the presence of thiocyanate, however, the peroxidase-like activity was inhibited in a concentration dependent manner. This makes the AgNPs/FP a promising catalyst and employed for colorimetric detection of thiocyanate via inhibition of the peroxidase-like activity. The application can be further extended to other environmentally and biologically important analytes.

“…FTIR spectra of unfunctionalized strips show a peak at 3337 cm −1 resulting from the stretching vibration of the abundant hydroxyl groups, and an intense peak at 1015 cm −1 due to the ethereal linkage (C−O−C) resulting from the skeletal pyranose ring on CP. Furthermore, FTIR spectra of CP have peaks at 2832, 1419, and 1365 cm −1 due to C−H stretching, −CH 2 symmetric bending, and −C−H bending vibration, respectively [41] . New peaks are not observed in the FTIR spectra of Pd/CP ( Supporting information , Figure S1).…”

Hallmark of a successful catalyst is its high efficiency, economic aspects, operational simplicity, extensive reusability, higher environment friendliness, and potential use in multiple industrial applications. Herein, a facile protocol involving a catalyst with Pd nanoparticles supported on cellulose paper (also known as a “dip‐catalyst”) for the hydrogenation of a series of quinolines, nitroarene, and C−C bond formation reactions in most benign solvents such as water is described. The mere insertion/removal of the “dip‐catalyst” strip enables instantaneous start/stop of the reaction, which enhances its reusability and ease of separation of products. Cellulose paper (CP) strips decorated with Pd nanoparticles (Pd/CP) are prepared by the reduction of K2PdCl4 soaked strips using formic acid as reductant. The resulting spherical shaped Pd particles, confirmed by scanning electron microscopy, form stable catalysis centers on the support. XRD signature confirms the crystallinity of the Pd nanoparticles and the TEM images display 15–20 nm size particles uniformly decorating CP. X‐ray photoelectron spectroscopy indicates the formation of metallic Pd. The catalyst is tested for the C−C bond formation reactions. Pd/CP catalyzed Suzuki‐Miyaura coupling reaction demonstrate >99% conversion with optimum selectivity. On the other hand, Mizoroki‐Heck reaction produced 87% conversion with the reaction of 4‐methoxycarbonyl phenylboronic acid and iodobenzene in ethanol:water (1 : 1 v/v) using KOH as base. The developed Pd/CP construct produces >99% of the pyridine‐ring hydrogenated product on quinoline hydrogenation using tetrahydroxydiboron (THDB) as the hydrogen source. Diverse and highly reducible functional groups were also evaluated for transfer hydrogenation, which demonstrates a high efficiency in terms of both reactivity and selectivity. The used catalysts are recyclable for the multiple cycles.
