“…The presence of AgNPs was captured in the form of white spherical particles deposited on the thread-like f-MWCNT. The SEM images also show the conformity with other carbon nanotubes SEM characterization references [33,[42][43][44]. The existence of oxygen functional group and AgNPs were confirmed by the EDS spectrum result presented in Figure 2c and d and the component analysis in Tables 1 and 2.…”

Dopamine (DA) is an important neurotransmitter in the kidney, cardiovascular system, and central nervous system, which abnormality is associated with many diseases. In this work, we synthesized a functionalized multi-walled carbon nanotube/silver nanoparticle (f-MWCNT/ AgNP) nanocomposites as the biosensing material to detect DA. The SEM, EDS, and TEM characterizations indicated the success of the functionalization process with MWCNT as the base material. The values of the linear range, the limit of detection (LOD), and the selectivity of the nanocomposite were all obtained from the Differential Pulse Voltammetry (DPV) measurements. The obtained LOD value was 0.2778 mM in the linear range of 0-8 mM, which is lower than the required concentration value for detecting DA in human urine (0.3-3 mM). The biosensor's high selectivity on DA with the presence of other human-related biofluids was also reported. These results show that f-MWCNT/AgNP nanocomposites are a promising biosensor material for the detection of DA.

“…The characteristic peaks in the FTIR spectra at 731, 756, 780, and 1088 cm −1 in CoPc/FePc HS indicate the presence of β-phase, which is consistent with the conclusion obtained via XRD. The characteristic peak at 911 cm −1 in CoPc/FePc HS belongs to the metal-ligand vibration band, indicating the existence of the M-N 4 macrocycle structure [48][49][50]. The stable M-N 4 macrocycle structure in CoPc/FePc HS is expected to facilitate rapid electron transfer during catalysis [51][52][53].…”

Bimetallic phthalocyanine heterostructure used for highly selective electrocatalytic CO2 reduction

Heterogeneous molecular catalysts, such as metal phthalocyanines, are efficient electrocatalysts for CO 2 reduction reaction (CO 2 RR). However, the rational design and synthesis of a molecular catalyst-based heterostructure for CO 2 RR remains challenging. Herein, we developed a crystalline bimetallic phthalocyanine heterostructure electrocatalyst (CoPc/FePc HS), which achieved an excellent CO 2 -to-CO conversion efficiency (99%) and outstanding long-term stability after 10 h of electrocatalysis. Density functional theory calculations revealed that the enhancement of CO 2 RR performance could be attributed to the distinct electron transfer pattern between FePc and CoPc. The heterostructural engineering in molecular catalysts would inspire a unique approach for improving CO 2 RR performance.
