“…It can assist the loading process of active catalyst species, facilitate good reactant transport, and expand the temperature range in reaction applications. It is known that mesoporous carbon can be impregnated well with various types of metals for multiple applications such as Ag [19][20], Pd [20], Ni [21][22], Co [23], Ru [24], and Cu [25]. In addition, mesoporous carbon is also a potential material to be used as a CO2 adsorbent [26][27].…”

Carbon dioxide (CO2) is a compound that can potentially be used as a carbon source in the synthesis of fine chemicals. However, the utilization of CO2 is still constrained due to its inert and stable nature. Therefore, the presence of a catalyst is needed in CO2 conversion. This study aims to synthesize copper impregnated mesoporous carbon (Cu/MC) as a catalyst for phenylacetylene carboxylation reaction with CO2 to produce phenylpropiolic acid. The synthesis of mesoporous carbon was performed via the soft template method. The as-synthesized Cu/MC material was characterized by FTIR, SAA, XRD, and SEM-EDX. BET surface area analysis of mesoporous carbon showed that the material has a high surface area of 405.8 m2/g with an average pore diameter of 7.2 nm. XRD pattern of Cu/MC indicates that Cu has been successfully impregnated in the form of Cu(0) and Cu(I). Phenylacetylene carboxylation reaction with CO2 was carried out by varying reaction temperatures (25, 50, and 75 °C), amount of catalyst (28.6, 57.2, and 85.8 mg), type of base (Cs2CO3, K2CO3, and Na2CO3), and variation of support. The reaction mixtures were analyzed by HPLC and showed that the highest phenylacetylene conversion of 41% was obtained for the reaction at 75 °C using Cs2CO3 as a base.

“…The sample was outgassed for 10 h under vacuum at 200 °C before measurement. The specific surface area was calculated using the Brunauer-Emmet-Teller (BET) equation, using data in the P/P 0 region between 0.05 and 0.15 [43,44]. The Barret-Joyner-Halenda (BJH) method was applied to analyze the pore size distributions using the adsorption branch.…”

Porous MnCo2O4 hollow nanocages have been fabricated via a simple template method using carbon spheres as a template. The hydrophilic surface of carbon spheres can adsorb Mn(2+) and Co(2+) ions simultaneously to form Mn,Co-adsorbed carbon spheres. The calcination of Mn,Co-adsorbed carbon spheres can result in porous hollow nanocages of MnCo2O4. The MnCo2O4 hollow nanocages are built by nanoscale MnCo2O4 crystals. Because of the unique porous hollow nanostructures, the resulting MnCo2O4/KB cathode shows an efficient electrocatalytic performance in LiTFSI/TEGDME electrolyte-based Li-O2 batteries. The MnCo2O4 hollow nanocages as the cathode catalysts can deliver better performance during the discharge/charge processes and good cycle stability compared with that of the pure KB carbon. The preliminary results manifest that porous MnCo2O4 hollow nanocages are promising high-performance cathode catalysts for Li-O2 batteries. This template technique is a simple, general, low-cost and controllable method and can be extended to prepare other transition metal oxide hollow nanostructures.

“…An electrode modified with metal NPs, such as Pt NPs [11][12][13][14], Au NPs [15][16][17], Pd NPs [18] and Ag NPs [3], has been widely used to prepare H 2 O 2 sensors due to their large specific surface area, excellent conductivity and extraordinary electrocatalytic activities. As typical nanomaterials, the controllable Ag NPs attached to a surface have been prepared for its good activity in SERS [19][20][21] and catalysis [22,23]. Recent studies have shown that the nanosized Ag NPs exhibited good catalytic activity for H 2 O 2 [24].…”

Silver nanoparticles (Ag NPs) attached to type I collagen-modified glassy carbon (GC) electrodes were successfully synthesized by the electrodepositing method. Atomic force microscopy images showed that many Ag NPs with homogeneous size were formed and uniformly distributed on the type I collagen/GC electrode. The amount, size and distribution of Ag NPs could be controlled by the collagen. The results of electrochemical experiments showed that Ag NPs had an excellent catalytic ability for the reduction of hydrogen peroxide (H(2)O(2)), suggesting that they could be used as a sensor to determine H(2)O(2). The good catalytic activity of the Ag NPs was ascribed to the type I collagen that resulted in the homogeneous distribution of Ag NPs with small size. The effects of type I collagen concentration and electrodeposition time on Ag NPs were investigated. When the Ag NPs were used as a sensor to determine H(2)O(2), the sensor could achieve 95% of the steady-state current in less than 2 s and had a linear range of 5.0 microM to 40.6 mM and a 0.7 microM detection limit of H(2)O(2) at a signal-to-noise ratio of 3.
