“…[30][31][32][33][34][35][36] Among them, the catalytic carboxylation of unsaturated compounds with CO 2 has received more interest. [37][38][39][40] However, compared to the broadly focused hydrocarboxylation of CO 2 with alkenes, [41][42][43][44][45][46] the catalytic functional carboxylation of CO 2 with alkenes is not widely reported since it is not easy to perform. Lately, Martin et al demonstrated the photocatalytic process under visible light between carbon dioxide and alkylcarboxylic acid.…”

“…Summarize, the kinetic equation for the reduction of nitrophenols and dyes can be represented as ln(Ct/C0) = −kt, where t is time for the catalytic reaction and, k is the apparent first-order rate constant (s −1 ) in Table-1. Moreover, the k' = k/M parameter (M: the amount of the catalyst) is introduced for quantitative comparison and the parameter is defined as the ratio of the rate constant k to the weight of the catalyst added [24]. In Table-1, the catalytic activity rate constant parameters were compared for the nanocomposite (M1).…”

The N-(3-((2-hydroxybenzylidene)amino)phenyl)benzamide Schiff base ligand (L) was synthesized and characterized. The ligand was immobilized on the fullerene material with a reduction copper material. The resulting nanocomposite Cu/Ligand@Fullerene (M1) was characterized by FE-SEM EDX, EDX mapping, FT-IR, and XRD techniques and tested as a catalyst for reduction of nitrophenols (2-nitrophenol (2-NP), 4-nitrophenol (4-NP)) and organic dyes (methylene blue (M.B.), Rhodamine B (Rh B)) under ambient temperature in water. The catalytic conversions and the reaction rate constant per total weight of the M1 catalyst were recorded as 89.9% at 300 s for 2-nitrophenol, 97.9% at 300 s for 4-nitrophenol, 90.6% at 360 s for Rhodamine B, and 98.3% at 60 s for methylene blue. For 4-NP, the reusability study was carried out as five cycles between 97.9%-87.3% conversions, respectively. The fabricated Cu/Ligand@Fullerene (M1) nanocomposite has good catalytic efficiency and reusability, low cost, and easy to produce.

“…Next, the obtained Pd-Cu bimetallic composite (BCM) was used as a catalyst to study its catalytic performance for the nitro compound (4-NP, 2-NA) [45][46][47][48][49][50][51][52][53]. As shown in Figure 5, the catalytic performance of Pd-Cu bimetallic composite (BCM) for 2-NA reduction was investigated.…”

Facile Preparation and Highly Efficient Catalytic Performances of Pd-Cu Bimetallic Catalyst Synthesized via Seed-Mediated Method

With the rapid development of industry, the problem of environmental pollution has become increasingly prominent. Exploring and preparing green, efficient, and low cost catalysts has become the key challenge for scientists. However, some conventional preparation methods are limited by conditions, such as cumbersome operation, high energy consumption, and high pollution. Here, a simple and efficient seed-mediated method was designed and proposed to synthesize a highly efficient bimetallic catalyst for catalyzing nitro compounds. A Pd-Cu bimetallic composite (BCM) can be prepared by synthesizing the original seed crystal of precious metal palladium, then growing the mature nanocrystalline palladium and supporting the transition metal copper. Importantly, after eight consecutive catalytic cycles, the conversion of the catalyzed 2-NA was 84%, while the conversion of the catalyzed 4-NP was still 72%. And the catalytic first order rates of 2-NA and 4-NP constants were 0.015 s−1, and 0.069 s−1, respectively. Therefore, current research of nanocomposites catalyst showed great significance for serious environmental pollution problems and the protection of living environment, providing a new idea for the preparation of new bimetallic catalytic materials.
